ArcelorMittal Europe delivered 60 000 tonnes of rails and 1000 tonnes of sections and flat bars for the 450-km Haramain High Speed Rail project also known as the “Mecca-Medina high speed railway" inaugurated on 25 September 2018.

A 300 km/h alternative

Located in Saudi Arabia, this new rail line connects the cities of Medina and Mecca. It was planned to provide safe and comfortable transport at speeds of 300 km/h, and it will help to relieve traffic congestion on the roads.

ArcelorMittal, a worldwide reference in high speed rail supply

To build the electrified double-track line, ArcelorMittal España supplied 60 000 tonnes of 25-metre-long 60E1 – R260 rails.

ArcelorMittal steel was chosen as we are a worldwide reference in high speed rail supply. We also have five facilities around the world for rail supply, of which four are located in Europe: Rodange (Luxembourg), Dąbrowa Górnicza, Chorzów (Poland), and Gijón (Spain).

A further contribution from Distribution Solutions Iberia

The rails are not the only contribution of ArcelorMittal Europe. Downstream Solutions Iberia provided (via its long-term customer, Dicome) 1000 tonnes of sections and flat bars produced in Olaberria and Bergara to realise the overhead power cable posts between January 2014 and April 2015.

Ho Chi Minh City is the fastest economic growing urban area in Vietnam. Landmark 81 will be a particularly impressive addition to the city’s skyline once complete in early 2019 overtaking Keangnam Hanoi Landmark Tower as the country’s tallest. This 81-storey residential structure will offer luxurious living combining extraordinary views with maximum floor space thanks to 3600 tonnes of HISTAR® 460 sections produced by ArcelorMittal Europe. The tower will be a notable achievement for ArcelorMittal too. For the first time, we will be the sole steel supplier of all the sections in a high-rise.

A new addition to the city’s skyline

Measuring 462 metres, Landmark 81 will be one of the tallest residential buildings on earth. Commissioned by property developer Vingroup, designed by architectural firm Atkins, structural design consulted by Arup, and built by construction companies Mace and Coteccons, it will make a statement in one of Ho Chi Minh City’s most prime locations facing the Saigon River. This 81-storey skyscraper will comprise a hotel, serviced apartments, and a high-end shopping centre.

Perfect for heavy loads and free fire protection

The 3600 tonnes of sections were produced by ArcelorMittal Europe – Long Products’ Differdange mill. The composite design of concrete and HISTAR® steels is ideal to carry heavy loads. The concrete walls contain multiple jumbo sections acting as vertical columns to carry the weight of the building. The concrete surrounding the steel columns also acts as free fire protection.

More floor area thanks to HISTAR®

A key advantage of HISTAR® steels will be an increase in saleable floor area. Vietnam is one of the few countries in the world where developers have to sell the net area of apartments or offices instead of the gross area. Inserting HISTAR® sections into the walls will enable builders to reduce their width freeing up additional saleable area at prime cost. By selecting HISTAR® 460 columns in composite walls, the structural engineer, Arup, succeeded in maximising the so-called “carpet area” for the benefit of the investor, Vingroup, as well as the future tenants.

In total, three lots of HISTAR® sections will be delivered to the steel fabricator QH Plus.  The first lot arrived in Ho Chi Minh City in early September 2016. Completion for Landmark 81 is expected in early 2019.

Steel Bridges Prague 2018

This two-day international event is organised by the Czech Constructional Steelwork Association (CAOK) with the European Convention for Constructional Steelwork (ECCS) and in conjunction with the ECCS Steel Bridge Awards Ceremony.

The symposium will showcase new products and the hottest technology solutions for steel bridges alongside a wide range of presentations and discussions relating to design, research, and projects in the steel bridges sector.

Link to website: www.steelbridges2018.com

You are invited

We warmly invite you to visit ArcelorMittal Europe – Long Products in the exhibition space and to take in the keynote speech from ArcelorMittal’s Head of Development and Technical Advisory – Bridges, Dennis Rademacher. Dennis will discuss maintenance free corrosion protection for composite bridges with hot-rolled sections.

A wide variety of other presentations will cover topics such as bridge architecture, construction, maintenance, case studies, high strength steel, sustainability, and much more.

Prague

Prague is home to one of the most beautiful bridges in the world. While not a steel bridge, Charles Bridge (Karlův most) sandstone block bridge flanked by fortified towers at each end is worth a look while you’re there!

Flying over Germany's highest mountain

At 2962 metres, Zugspitze is Germany's highest mountain and highest ski resort. There, you can enjoy powdery ski slopes in the winter and hiking trails in the summer. To transport visitors to the summit, a new cable car was installed. Its construction involved HD profiles supplied by ArcelorMittal Europe – Long Products and ArcelorMittal Downstream Solutions in Neckarsulm.

The world's highest structural support for aerial tramways

After three years of planning and construction, Zugspitze’s new cable car started its ascent last winter. For this unique project, our colleagues at ArcelorMittal Europe – Long Products, together with ArcelorMittal Downstream Solutions, delivered HD profiles in steel grade S355 J2, which were used to build the structure of the cable car. The beams were produced in ArcelorMittal’s Differdange mill in Luxembourg, where they were cut to length, and the team at ArcelorMittal Downstream Solutions in Neckarsulm sold the final products to the customer.

Zugspitze's cable car holds three world records:

1. First, the particularity of this cable car is that instead of using two supports, it only has one support measuring 127 metres high making it the tallest tramway support in the world.
2. Then, the distance between the support and the mountain summit station is 3213 metres.
3. Finally, another unique feature is the height difference of 1945 metres between the valley station and the mountain summit station.

A new era

The modern cable car is a strong investment marking the beginning of a new era for the Zugspitze mountain.The 50-million-euro project has been providing visitors with maximum comfort and giving tourism a boost throughout the region.

So far, around half a million visitors are transported annually, but the historic Eibsee cable car from 1963 reached the limits of its transport capacity on peak days. The new cable car should attract about 10 percent more passengers, which means an increase for the entire, predominantly touristy, region.

The two new cabins with a sparkling new and elegant design can carry up to 120 passengers each with the floor-to-ceiling glazed open-plan cabins offering grandiose panoramic views of Germany's highest peak. They now guides alpinists, summer hikers, winter sports enthusiasts, and tourists from all over the world to the mountain top.

These best practice design manuals consist of a series of technical guides for engineering offices, steel fabricators, and architects that aim at facilitating the application of the Eurocodes in the design of single-storey and multi-storey steel buildings.

The presented design manuals consist of a series of technical guides facilitating the application of the Eurocodes in the design of single-storey and multi-storey steel buildings.

These design manuals are helpful for steel fabricators and engineering offices, but the presentation of the advantages and possibilities of the use of steel also applies to architects. They provide a useful source of knowledge for designers in accordance with the Eurocodes and include topics such as numerous design details, fire engineering issues, member and connection resistance calculators, etc.

The design guides 'Single-Storey Steel Buildings' and 'Multi-Storey Steel Buildings' were produced in the framework of the European project 'Facilitating the market development for sections in industrial halls and low rise buildings (SECHALO) RFS2-CT-2008-0030', which was carried out with a financial grant from the European Union's Research Fund for Coal and Steel.

The design guides were prepared under the direction of ArcelorMittal, Peiner Träger, and Corus. The technical content was prepared by CTICM and SCI, collaborating as the Steel Alliance.

Leading engineering consultancy WSP have released a paper as part of their Future Ready research based on consultation with organisations across sectors that could decrease time and costs in the construction industry by cutting resource use by 23%.

Circular thinking for increased efficiency and sustainability

The paper offers ten practical recommendations on circular design from WSP and supporting organisations, including ArcelorMittal, for ‘the implementation of resource-efficient, circular thinking in the built environment and infrastructure sectors at scale’.

Resources used in construction usually function in a linear form. At the end of their life cycle, resources are destroyed or removed and while some are recycled, most are wasted. This is far from cost-efficient or sustainable.

According to David Symons, UK Director of Sustainability at WSP, “The construction industry is the largest user of resources in the UK economy today, so it needs to take rapid action. We have to do something different and these 10 actions from WSP and supporting organisations show how the industry is stepping up and taking a leadership position itself.”

Call for action

The paper proposes changes in four key areas: skills, standards & policy, finance & procurement, and records & evidence. In addition, it calls on a wide range of sectors to take part such as government, education & training, EPDs, industry standards, waste strategy, and storing & sharing knowledge of resource-efficient designs.

Practicalities for the future

Circular design thinking with ‘adaptable, modular design for building and infrastructure and new business models, such as leasing materials’, are necessary if countries like the UK want to meet government targets and double their resource productivity by 2050.

Author of the paper and WSP consultant George Baker adds that “It makes complete sense to embed these recommendations into government policy now. They focus on the delivery of a key objective of the Industrial Strategy, the 25 Year Environment Plan and the Clean Growth Strategy.”

ArcelorMittal continues to leap forward in steel solutions with the release of Steligence®. Ushering in a new wave of high-performance building and construction techniques, this fresh and innovative concept ensures that each steel component interacts in a complementary way.

"Taking a holistic approach to sustainable construction." (Prof. Olivier Vassart)

Steligence® was developed after a number of years of scientific and industry reviewed research that has resulted in a profound new approach to construction built on a strong foundation of sustainability.

Addressing current issues in the building industry, Steligence® is a philosophy that incorporates all elements of design and encourages more communication among the architectural and engineering experts involved in a building project.

Keeping only the strongest elements of traditional construction methods, Steligence® incorporates the best available technology in steelmaking and a new and fresh approach to sustainability in terms of the overall design process and the future life of a building.

The Steligence® approach includes a broad range of steel products for construction which individually add value, but together represent a compelling portfolio with a range of defined benefits.

A win-win solution

During a speech at the London launch event, Greg Ludkovsky, ArcelorMittal’s global head of research and development, explained that “as climate, energy and resource scarcity intensifies, win-win solutions like Steligence® become imperative for business and society at large. Buildings play a huge part in all our lives, so creating a construction concept that improves their social, economic and environmental impact while dramatically enhancing their functionality and aesthetics has been a huge but important challenge.”

ArcelorMittal Europe – Long Products Rails and Special Sections provided 6,500 tonnes of rails for the forthcoming Sydney Metro project. It is Australia’s largest public transport infrastructure project as it will transform Sydney, delivering more trains and faster services for customers across the network.

Sole supplier for the first phase

ArcelorMittal is the sole steel supplier for the first phase of this project and provided 6,500 tonnes of rails produced by ArcelorMittal España, in Gijón. 20-metre long rails were delivered at the Port of Newcastle in March.

ArcelorMittal was chosen for the Sydney Metro project as it is a worldwide reference, able to offer rails that combine excellent reliability and the highest quality, without forgetting other requirements such as safety, durability, cost efficiency, service, and environmental-friendliness.

The first fully-automated metro rail system in Australia

This first phase consists of a new 23-kilometre rail route that calls for six new stations and the possibility of two more in the future. It is on track to open to customers in the first half of 2019 and deliver fast, safe, and frequent service.

The City & Southwest will be the second stage with a new 30-kilometre metro line, scheduled to open in 2024 with the capacity to run a metro train every two minutes each way under the centre of Sydney. It will also be the first fully-automated metro rail system in the country.

ArcelorMittal Projects, ArcelorMittal Europe – Long Products Sheet Piling, and Global R&D participated in a project financed by the Dutch government to improve the design of dikes and keep the Netherlands safe from flooding.

Exploring economical and innovative solutions for safety

The Netherlands is a low-lying country protected from the sea by dikes and dunes. For decades, dike reinforcements have been installed to keep the country dry and prevent floods from happening. Due to continuously increasing safety demands and loads, one third of Dutch dikes do not meet safety requirements.

Macro-instability is one of the most common causes. It can occur when a high water level pushes against the embankment. This causes saturation of the soil and loss of stability resulting in large parts of the dike body sliding away.

When there is a lack of space due to cultivation around the dike, reinforcements to prevent macro-instability are utilised. Dikes with steel sheet pile walls are very strong and do not have to be widened thus reducing objections from residents and time-consuming judicial procedures.

Given the Dutch safety challenge, the need for cost saving has risen over the last couple of years. The government is making a tremendous effort to search for innovations that will allow for the necessary cost saving.

Taking part in the governmental study team

To investigate how the sheet pile design standards can be optimised, the government decided to finance dike tests in Eemdijk in the province of Utrecht.

The tests focussed on gaining a better understanding of the interaction between the soil and the steel sheet piles. A team consisting of ArcelorMittal Projects, ArcelorMittal Sheet Piling, and the R&D department contributed to the design process. ArcelorMittal also provided GU8N and AZ26-700 sheet piles for the tests. They were produced by ArcelorMittal's sheet piling mills in Dabrowa, Poland and Belval, Luxembourg.

The choice of the sheet pile profile in combination with the steel quality was crucial for a successful test. All dimensions of the sheet piles were extensively tested to ensure an accurate mapping of the profile characteristics. Additional tensile tests were performed to determine the exact mechanical features.

This testing program was part of the Project Transcending Exploration Macro stability (POV-M)*, which is under the Flood Protection Program (HWBP)*. The tests even gained attention at the international level from the US Army Corps of Engineers to delegates from South Korea and China.

*The sheet pile tests were executed in cooperation with Waterboard Vallei and Veluwe, Deltares, Witteveen+Bos, Fugro, and ArcelorMittal.
**A cooperation between Rijkswaterstaat (The Ministry of Infrastructure and the Environment) and the water boards.

Test setup and process

At the Eemdijk test site, an oval shaped dike of 5m high, 60m long, and 40m wide was constructed in six months’ time. The dike was fitted with measuring equipment and was only used for this experiment which helped to increase knowledge of soil-structure interaction. After the tests, the dike will be completely removed. A total of three tests have been performed at the site with our sheet piles produced in Dabrowa and Belval.

Full Scale Test Green Dike: This part of the dike was constructed with a sand core and an outer cover layer of clay. The groundwater level inside the core of the levee was slowly raised to +2.80 metres, at which moment a sliding plane occurred and the dike collapsed. This test acted as a baseline measurement which was used as reference for the final test.

Pull Over Tests: Four different sheet pile configurations were installed 14 metres into the ground after which they were pulled over with a hydraulic cylinder. The objective was to see at which force level (with a maximum of 100 tonnes for AZ26-700) and which deformation the sheet pile wall would collapse. Additionally, the four configurations gave insight into the differences in the behaviour of a continuous wall and loose panels and between the elastic and plastic behaviour of the steel sheet piles.

Full Scale Test Blue Dike: This part of the dike was built similarly to the green dike apart from the reinforcement, which was over 60 metres with GU8N sheet piles. These piles were placed as triplets and staggered with lengths of 18 and 9 metres. This test was a combination of the above-mentioned tests and was the main test of the research.

A 2-metre-deep ditch was dug at the bottom of the blue dike. The groundwater level in the dike body was slowly raised and the filling of the water basin behind the levee was carried out over time. This led to a water level at the crest of the dike located at +5 metres. In addition, seven containers filled with water were placed on top of the dike, creating an extra load of 40 tonnes per container. Despite the combination of the huge loads, the steel sheet pile reinforced dike refused to give way.

By infiltrating the landward slope of the levee and lowering the water level in the ditch, the dike finally collapsed. Two million litres of water flowed out of the basin into the hinterland highlighting the success of the tests.

Saving 20-30% of steel

The dike, reinforced with steel sheet piles, finally collapsed but only after putting an extreme load on it; not collapsing the dike would have resulted in a less successful test.

Results of the different tests were in line with realistic predictions which are even more favourable than current calculation rules. This concludes that steel sheet pile walls are an extremely strong and practical solution for dike reinforcements.

Existing dike reinforcement projects cost an average of 15 million Euro per kilometre of dike. It is estimated that with these updated design rules, 20-30% of steel can be saved in new projects. With this cost savings, it is anticipated that the market share of the “innovative” steel sheet piles will increase in future dike reinforcement.

Giving structure to Romanian stadiums

Sport has a very important place in Romania, especially football. ArcelorMittal Tubular Products Europe recently contributed to the construction of two stadiums in the country: the Craiova stadium, inaugurated in November 2017, and the Targu-Jiu stadium which will open this year. Steel produced in Romania was used for both projects with Hollow Structural Sections (HSS) produced in Iasi and made from coils produced by ArcelorMittal.

About the stadiums

Craiova stadium:

Architect: Dico and Tiganas architecture and engineering
Contractors: CON-A S.R.L., ACI CLUJ S.A., and NISAL S.R.L.

Targu-Jiu stadium:

Architect: Dico and Tiganas architecture and engineering
Contractors: ACI CLUJ S.A. and CON-A S.R.L.

100% Romanian steel from ArcelorMittal

Two football stadiums were recently built with ArcelorMittal steel, in Craiova and in Targu-Jiu. For both projects, ArcelorMittal Tubular Products Europe supplied HSS (in EN 10219 standard) to KonigFrankstahl, which were used to build the tribunes and the structure of each stadium.

The HSS were produced by ArcelorMittal Tubular Products Iasi, part of ArcelorMittal Tubular Products Europe. The sections were produced through the Electric Resistance Welding process, which consists of forming a tube with a steel strip by heating the edges and forming them together. The name of the process comes from the heat necessary for welding that is generated by electric currents passed through the steel strip prior to the weld being forged.

Quality, communication and just-in-time delivery

KonigFrankstahl is one of ArcelorMittal Tubular Products Europe’s most important distributors for the Romanian market. KonigFrankstahl has a long-term and strong partnership with one of Romania’s largest
construction companies CON-A (general contractor of these two projects) which demands punctual deliveries to be able to meet project deadlines. KonigFrankstahl received the HSS based on CON-A’s specifications in full bundles from ArcelorMittal Tubular Products Iasi to its warehouses in Bucharest and Sibiu and was able to deliver the material in the exact quantities, even cut pieces, to the different requested locations.

Three main factors convinced KonigFrankstahl to opt for ArcelorMittal products:

• the quality of the products, supported by certificates

• ArcelorMittal’s ability to ensure just-in-time delivery

• excellent communication with ArcelorMittal

Moreover, the collaboration with ArcelorMittal Tubular Products Iasi was very good due to the high support provided from production to logistics despite the high pressure regarding deliveries.

The Craiova stadium, inspired by modern art

The Craiova stadium located in the city of Craiova has a capacity of 30,000 seats and replaces the former Ion Oblemenco Stadium built in 1967. The new stadium was designed by the architects Dico and Tiganas architecture and engineering who took inspiration from the work of art “Mademoiselle Pogany,” carved by Romanian sculptor Constantin Brancusi. The iconic building offers a modern touch that will boost the development of the local area.

The building envelope has an elliptical shape, which protects the spectator seating area against adverse weather conditions while ensuring that the natural light hits the pitch and closes the secondary spaces under the stands. The volume of the bowl is enhanced thanks to the semi-open roof and the structural "ribs" wrapped with transparent and translucent materials.

The Targu-Jiu stadium comes into line with UEFA standards

Work at the new stadium in Targu-Jiu (in the south of Romania) is nearing completion; the tribune roofs are partially mounted, as well as the two scoreboards. The project involves the reconstruction of the Targu-Jiu Stadium to make it more modern and in line with the UEFA standards. Once completed, the stadium – which should be officially named Pandurii Arena - will have 12,500 seats and will also include an underground car park and a 40-room hotel. In the near future, the area around the stadium will enter into a modernisation process.

On 10 February, the ČEZ City Cross Sprint skiing competition took place in Ostrava. Skiers competed under the blast furnaces and other facilities at Dolní Vítkovice, a former industrial area protected by UNESCO, which also hosts the Bolt Tower, a helix of 78 metres built with steel from ArcelorMittal Ostrava. This tower, which now includes an observation point, multifunctional spaces and a café, was named after Olympic champion Usain Bolt, who inaugurated the tower in 2015.

A former industrial complex turned into an educational, social, and cultural centre

Dolní Vítkovice is a former industrial area located near Ostrava. After its last blast furnace was shutdown in 1998, the government declared the area a national site. In 2009, it was decided it was time to breathe new life into Dolní Vítkovice, making the site accessible to the public and using it for educational, cultural, and social activities.

ArcelorMittal steel in the 2015 Building of the Year

As the largest steel producer in the Czech Republic, ArcelorMittal Ostrava proudly contributed to the construction of the Bolt Tower. Our mill supplied nearly 500 tonnes of steel for the construction of the tower, split between flat bars, angles, seamless tubes, and sheets.

Architect Josef Pleskot is behind the design of the Bolt Tower, which is reminiscent of the fire that constantly burned at the time when the metallurgical plants were functioning. The result is a steel and glass construction of 14.1 metres mounted on top of the 63.6-metre former blast furnace.

The construction of the tower began in February 2014 and the first visitors were welcomed in May 2015. The same year, the project was awarded the Building of the Year award in the Czech Republic.

Named after the fastest man in history

The Bolt Tower is geographically the highest point in Ostrava, making it a unique observation tower. It got its name from bolt (a metal bar) and from athlete Usain Bolt, world champion and Olympic winner, who officially lent his name to the Tower during the official inauguration in May 2015.

A unique education, social, and cultural centre

Apart from an amazing view of the Beskid Mountains and of the surrounding area, the Bolt Tower also offers a café and a club where students head for technical education. Guided tours are organised to present how hot metal was produced in the blast furnace at the time of its operation. The industrial complex has now been transformed into a unique educational, social, and cultural centre. On the premises you can find a Science and Technology Centre presenting science and technology as an entertaining game and a cultural area Hlubina, attracting not only musicians and bands but also sculptors, designers, visual artists, and music concert lovers to a variety of cultural events.

Managing the negative temperatures is a real challenge in the construction industry in Scandinavia. ArcelorMittal Europe – Long Products' mill in Hamburg has been working with Swedish customer Hjulsbro Steel for five years, providing them with wire rod used to reinforce concrete in low temperatures. Two major bridge projects emerged from our collaboration: the Lysefjord Bridge in Norway and the Öresund Bridge linking Denmark and Sweden.

Concrete modules: the solution to build at -40°C

Scandinavian cold temperatures can be harmful for construction companies. The lowest temperatures in Finland can go from -20°C to -40°C in the north. Unfortunately, it is difficult to process concrete under 5°C without thermal insulation. To tackle this issue, construction companies use concrete elements. The idea is simple: while in Central and Southern Europe concrete work is carried out directly on the construction site, Scandinavia produces finished concrete parts in special factories all year round, irrespective of adverse external temperatures. These elements are then placed on the construction sites and can be assembled there in any weather.

In order to reinforce these concrete parts, steel strands are used. These stressed and twisted steel strands are made from three to seven high-strength steel wires to reinforce the concrete elements to the desired strength. "In Scandinavia, shopping centres, supermarkets, and office buildings are now mainly built using concrete elements," explains Arto Mustonen, Managing Director of Hjulsbro Steel.

From Hamburg to the Baltic states

Since 2012, Hjulsbro Steel has bought from ArcelorMittal a substantial part of the 30,000 tonnes of steel wire rod that is processed in its plant every year. ArcelorMittal operates its own warehouse in Sweden, in Norrköping, which is directly supplied from Hamburg and can deliver Hjulsbro Steel.

ArcelorMittal Hamburg produces wire rod with a high carbon content and a diameter of 8.5 to 12 millimetres. Hjulsbro Steel processes these wires and draws them to 3 to 5 millimetres in diameter to create steel cables of 6.5 to 15.7 millimetres in diameter, which are mainly used for the reinforcement of concrete elements. This technique has many advantages; the steel strands which are stretched during the production of the module and then recombined in the finished concrete part help to increase its strength. This means larger spans, ceilings, and walls built significantly thinner with the same strength and no concrete work on the construction site.

"Building with reinforced concrete elements is a growing market," says Arto Mustonen. "The construction industry is very conservative, and it takes a long time to develop new processes that could be expanded to other European countries."

Flexibility and quality ensuring a strong partnership

Mustonen appreciates the great flexibility that is given to him in the delivery of steel, and of course, the high quality of our steel. "Our products are subject to strict controls by the national authorities in each country, which precisely dictate the characteristics of our steel," he says. "The rules are very strict and we must always adhere to the standards to keep our approvals."

With the development of this construction technique, steel concrete modules with ArcelorMittal wire rod might soon be used not only in Scandinavia, but also in winter construction sites in Central Europe.

Our wire rod in major bridges in Scandinavia

Our partnership with Hjulsbro Steel led to the construction of two major bridges:

• The Lysefjord Bridge in Norway, measuring 639 m, was built using prestressed concrete. The railroad ties were produced with prestressed concrete and prefabricated concrete elements with prestressed concrete.
• The Öresund Bridge, measuring 7 km, links Sweden and Denmark; Hjulsbro Steel delivered prestressed concrete steel strands for the tunnel.

Located in Chorzów, the Silesian stadium (or Stadion Śląski) is one of the most recognisable stadiums in Poland. Inaugurated in 1956, the stadium was recently completely renovated and reopened in October 2017. ArcelorMittal Europe – Long Products contributed to the project and provided sheet piles, used to secure the foundations.

A popular place for sports and music

First opened on 22 July 1956 and described as a symbol of Polish football, the Silesian stadium served for many years as a national stadium. Until 2009, It hosted 55 football matches involving Poland’s national football team, and welcomed many international football stars such as Pele, David Beckham and Cristiano Ronaldo. The Silesian stadium was also a popular place to organise concerts and many rock bands performed there such as U2, the Rolling Stones, Red Hot Chili Peppers and Linkin Park.

325 tonnes of sheet piles from Dabrowa to secure the foundations

Recently a major overhaul of the stadium was completed to bring it up to modern standards. For this renovation, ArcelorMittal Poland supplied to customer, PPI Chrobok SA, 325 tonnes of GU16-400 sheet piles in grade S355GP and measuring between 8 and 12 metres. 

The sheet piles, produced by ArcelorMittal Europe – Long Products in Dąbrowa, were used to secure the foundation trench in the area of the pitch plate. The long-term relationship between Dąbrowa and the customer, as well as the proximity of the mill and the availability of the stock were determining factors in winning this contract. Our sheet piles solution is quick to install, even in hard soil conditions.

After modernisation, the Silesian stadium can now welcome 54,378 spectators during games and 85,000 people during concerts.

It is currently the biggest athletics stadium in Poland.

Facts and figures about the Silesian stadium

•  54,378 places
•  85,000 places during concerts

ArcelorMittal Construction is another entity of our company who participated in this project. While our sheet piles were used for the construction of the stadium, ArcelorMittal Construction Polska also supplied curved steel profiles for the roof of three cable car stations located next to the stadium. The curved steel profiles in green 1018 were supplied to customer Mostostal Zabrze, who built the stations.

Steel is a familiar material for Belgian sculptor William Roobrouck. But when he decided to realise his latest artwork, Roobrouck turned to Indaten® weathering steel for the first time. Called ‘Désir Perceptible’ (Perceptible Desire), the monumental sculpture celebrates the longing couples can feel for a child. Thanks to Indaten® from ArcelorMittal Europe – Flat Products, Désir Perceptible will stand the test of time, and the rigours of the Belgian coast.

“I have a passion for steel which started when I was about six,” says William Roobrouck. “Around then I began to take my summer holidays with my grandparents on the Belgian coast. My grandmother was an artist, so I learnt painting from her, while my grandfather was an engineer in the aviation industry. He taught me a lot about working with metal.”

“When I was about eight, I started to study at the Academy of Art in Ghent. Over the next four years I went there every Saturday to develop my drawing and painting skills, and I also learned to make sculptures in clay. It was a good base for the art and sculptures that I make today.”

“After finishing school, I put my art on standby. But by the time I reached 30, I realised that I still had a passion for art and that it was something I wanted to pursue in my life. Although I did have my early experiences to fall back on, I’m largely self-taught. I’m curious about how things are made, how they work.”

Warm colours of Indaten® reflect desire for family

“I've used steel a lot in my sculptures, but Désir Perceptible is my first artwork in Indaten®. This sculpture represents a couple who desire a child. As it ages, Indaten® develops an orange, amber colour. It is a warm colour and it relates to the warm feeling you get when you think about bringing a child into the world.”

“Désir Perceptible began with very simple lines. Once I realised that I had a very strong artwork, I decided to make it in steel. I took a plate of Indaten® and drew the outline with chalk. When I was happy with the image I took a manual plasma cutter and cut the front and back out of Indaten®. It then took me some time to clean it up. Many people will wonder why I didn’t use a laser cutter as that is much cleaner. But it lacks the human touch – something that I think was very important with this subject.”

“I then cut strips to create the parts that join the front and back of the sculpture. While that was relatively easy for some parts, the head and inside of the child were difficult to form. I relied on a friend who had some rolling equipment to help me with that. With my friend’s advice – and some trial and error – I managed to achieve the result I wanted.”

Seawater gets the ageing process started

“Inside, the front and back are held together with steel tubes. Although they were not needed once the side strips were added, I left them in. They can be connected to tubes which go into the ground. This secures the sculpture and stops it falling over in the wind, or being stolen. Though at around 250 kilograms it probably weighs too much to be stolen!”

“In total it took three months to realise Désir Perceptible as I was working outside and at the mercy of the elements. I have a studio, but it was not big enough for this sculpture.”

“Désir Perceptible was finished in August 2017 and I immediately wanted to show it in an art exhibition that was held in the village where I live. To get the Indaten® ageing process started quickly, I soaked the sculpture in seawater. Almost overnight the warm orange tones of the steel started to show.”

Indaten® ensures the sculpture will endure

“Even though it appears to be corroding in front of your very eyes, Indaten® is actually much more resistant to corrosion than untreated carbon steel. Where untreated steel might last for 20 years, Indaten® will endure for up to 120 years, even in marine environments.”

“I’ve been invited to display Désir Perceptible at Tentuinstelling 2018. The name is a play on the Flemish words for exhibition (tentoonstelling) and garden (tuin), as the exhibition is held in gardens along the coast.”

“I’m also using Indaten® to create another sculpture for Tentuinstelling 2018. The second one will be about ten-metres high. Again, I’ve chosen Indaten® because of its ability to withstand the harsh environment of the Belgian coast.”

About Indaten®

Indaten® is a structural steel with excellent resistance to atmospheric corrosion, thanks to its protective and adhesive patina which evolves with time and the effects of the environment. Over time, the steel surface develops a beautiful purplish brown patina which acts as a protective armour for the steel.

As from 2020, Kuwait will have a new liquefied natural gas (LNG) terminal, located near Kuwait City which will produce approximately 22 million tonnes of natural gas every year. For the construction of this impressive facility, ArcelorMittal Special Rebars & Thread Bars and ArcelorMittal Projects work jointly to supply Krybar®, a special concrete reinforcing steel bar providing safety for cryogenic applications.

A liquefaction capacity of 30 billion m3 per day

The Al-Zour LNG terminal is located in the Al-Zour region, about 90 km south of Kuwait City, close to the border with Saudi Arabia. This project includes the construction of a re-gasification facility, eight storage tanks and marine facilities.

Once completed and fully operational, the Al-Zour LNG terminal will have:

•     a production capacity of 22 million tonnes of natural gas every year
•     a storage capacity of 1.8 million m³ of natural gas
•     and a liquefaction capacity of 30 billion m3 per day

The owner of the project is Kuwait National Petroleum Company (KNPC), a subsidiary of Kuwait Petroleum Corporation, which awarded Hyundai Engineering & Construction Co., Ltd. (HDEC) – a consortium including Hyundai E&C and state-owned Korea Gas Corporation (KOGAS) – for the construction of the terminal.

The biggest supply contract ever booked for Krybar®

ArcelorMittal Special Rebars & Thread Bars teamed up with ArcelorMittal Energy Projects (Oil&Gas) in Singapore to provide Krybar®, a durable reinforcing steel capable to resist low temperatures up to -170°C.

During the early bidding stage in 2015, ArcelorMittal Projects Oil & Gas in both Singapore and Korea followed the project closely. They promoted Krybar® and supported various EPCs, with, amongst others, Hyundai Consortium. In February 2016, Hyundai Consortium was awarded the EPC contract, and their Korean partner, KOGAS, was then entrusted to the design of this major ‘Design & Build’ contract.

After a successful visit of KOGAS’ technical delegation to ArcelorMittal Warszawa (Poland) in 2016, Krybar® was finally approved for the project.

In total 5,520 tonnes of Krybar® 620 (in 20mm, 25mm and 28mm diameters) produced by ArcelorMittal Warszawa will be supplied for the construction of the eight storage tanks, each with a capacity of 225,000 m³. This project represents thebiggest supply contract ever booked by ArcelorMittal Europe – Long Products and ArcelorMittal Projects for Krybar®.

Krybar® in more than 300 tanks worldwide

Krybar® is a special concrete reinforcing steel designed on demand of the LNG industry in order to provide safety for cryogenic applications. Its special composition and rolling process give Krybar® a high ductility even at very low temperature, down to -170°C, making it ideal for the construction of gas tanks (LNG and LPG) and ethylene tanks.

ArcelorMittal offers a wide range of Krybar® grades depending on the design temperature of the tank:

•     Krybar® 50 for LPG tanks with temperature down to -50°C
•     Krybar® 105 for Ethyl tanks with temperature down to -105°C
•     Krybar® 620 & Krybar® 165 for LNG tanks with temperature down to -170°C

ArcelorMittal has been producing Krybar® since 1980. Since July 2014, its production takes place in the new rolling mill of ArcelorMittal Warszawa.

ArcelorMittal Méditerranée recently inaugurated a photovoltaic farm on its site of Fos-sur-Mer, realised in partnership with EDF Energies Nouvelles. This solar farm of 15 hectares has a capacity of 12 MWc, equal to the annual electricity consumption of 7,400 citizens, half of the town of Fos-sur-Mer. Profil du Futur, a division of ArcelorMittal Construction, was in charge of the structure’s construction and used Magnelis®,a lead product of ArcelorMittal Europe – Flat Products for solar projects.

45,000 solar panels installed in 10 months

La Fossette solar farm is composed of 45,000 solar panels and its full construction required 10 months of work and up to 40 people. The solar panels structure was designed and produced by Profil du Futur in Horbourg-Wihr (near to Colmar, in France) and with steel produced by ArcelorMittal Bremen and coated with Magnelis®.

Based on DMSE’s specifications (the consulting firm mandated by EDF Energies Nouvelles), Profil du Futur proposed a structure designed in accordance with the Eurocodes standards that could meet all the needs (soil condition (determined by the G2AVP study), climatic loads, handling in the ground, modules fixing method, etc.).

The poles are the first steps in the installation of a solar structure. For La Fossette project, micropiles were the selected method, due to the nature of the ground (rocky with large blocks). This solution involves drilling the soil to a certain depth and to a certain diameter to install the pole and pour concrete into the hole around the pole. Before installing the micropiles, pulling tests are made to check how the poles will hold in the ground.

The photovoltaic modules of La Fossette were manufactured by the company TRINA and to realise the mounting parts which hold the modules on the structure, Profil du Futur partnered with Araymond who designed and manufactured the clamps.

Magnelis®, the reference material for solar projects

The structure of La Fossette solar farm was entirely made with Magnelis®, an ideal material for solar applications. Its remarkable corrosion resistance comes from its unique composition; developed by ArcelorMittal Europe – Flat Products, the coating includes zinc, 3.5% aluminium, and 3% magnesium. Magnelis® has a self-healing effect on cut edges and scratches which ensures excellent edge protection, even in the most hostile environments. When exposed to the environment, Magnelis® forms a very dense, zinc-based protective film. This film also forms on edges, welds, perforations, and scratches. It is almost impossible for the environment to penetrate this film.

La Fossette is the first project that EDF Energies Nouvelles realises with Magnelis®. Since 2012, Profil du Futur has made continuous efforts to make Magnelis® known as a suitable product for solar applications. This prescription as well as the 25-year guarantee were key factors which convinced EDF Energies Nouvelles to work with us.

Magnelis® wasn’t the only ArcelorMittal product used for this project. ArcelorMittal Fos-sur-Mer provided slag to consolidate the paths on the solar farm. Steel-making slag is a by-product of the steel production and often used in civil engineering to consolidate embankments.

A fruitful collaboration for Fos-sur-Mer

The completion of this project is part of the EDF Group's CAP 2030 strategy, which aims to double its renewable capacity by 2030. For ArcelorMittal Méditerranée, the aim is to facilitate the production of renewable energy by making parts of its industrial lands available. The last 5 years, the company invested €60 million for sustainability and remains attentive to the residents’ remarks.

Last year, German magazine Der Spiegel published an article about the collapse of old bridges in Germany - mostly due to heavy vehicles traffic - and the efforts made to reconstruct and modernise them. The reconstruction of the bridge "Demminer Strasse" in Neubrandenburg with ArcelorMittal beams shows that steel is an ideal bridge solution, providing a sustainable, quick and economic construction.

Composite solution for more resistant structures

To rebuild the bridge "Demminer Strasse" in Neubrandenburg, general contractor Matthäi Bauunternehmen Leezen opted for a filler beam deck solution. This kind of steel-concrete composite bridge is used for short and medium span superstructures with severe construction depth restrictions. The new two-span bridge has two separated decks for each traffic direction. It is built over railway tracks and provides further connections via the B96 road.

As ArcelorMittal Downstream Solutions successfully collaborated with Matthäi Bauunternehmen Leezen for a precedent bridge project in Schwerin, we won the contract in May 2016 and delivered H-profile wide flange beams in grade S355M with a profile depth of 900 mm each. Due to the closely spaced beams and prefabricated fibre-cement elements, which are placed on the lower flanges, no additional formwork or falsework for the concrete between the beams was needed. Thus, traffic interference below the new bridge was strongly reduced and expensive closure times for the railway line could be limited to only few nights.

Sustainable beams from Luxembourg

The 19 and 31-metre-long beams were produced by ArcelorMittal Europe – Long Products' mill in Differdange (Luxembourg). Afterwards, they were cut and welded with transversals (IPE 400 S235JR) by Downstream Solutions in Bad Oldesloe (Germany). The thermomechanical rolling process of the high quality S355M grade associated with the anti-corrosion coating applied on the beams will ensure the longevity of the structure.

The beams, like most of our steel beams used in bridge construction, were made of scrap. This once again demonstrates the sustainability of steel, which can be recycled infinitely many times while retaining its properties.

Downstream Solutions and ArcelorMittal Europe – Long Products coordinated their deliveries with the customer and Deutsche Bahn, ensuring that assembling of the beams could take place at night in July without any problems. The construction of the bridge will be completed in the first or second quarter of 2018.

On September 17 2015, the steel at U.S. Bank Stadium topped off, marking a major milestone in the construction of this new stadium, which has been constructed with 3,080 tonnes of our HISTAR® beams. Now, almost 2 and a half years later, it hosted the most important American Football event - with the Philadelphia Eagles as the big winners!

A roof 30% lighter

The trusses supporting the roof of the U.S. Bank Stadium were built using 3,080 tonnes of HISTAR® beams in grade 65 ksi. Produced in Differdange (Luxembourg), HISTAR® was the best solution for this project, as it enabled reduction of the weight of the roof by more than 30%. Finishing the steel erection marked more than 70% completion for the entire stadium project.

Exceptional design

U.S. Bank Stadium, home to the Minnesota Vikings NFL team, has an estimated construction cost of $ 1 billion and will have a capacity of 65,000 people. The stadium features a translucent fixed roof and five 29-meter-tall pivoting glass doors, which serve as a grand entrance to the facility and let in ample amounts of natural light. As 60% of the roof structure is transparent, stadium users will view the sun and sky throughout the year while staying in a climate-controlled environment.

The stadium was officially inaugurated in July 2016.

Located in the vibrant cultural and heritage district of Bugis in Singapore, DUO is a new real-estate development which opened its doors on 15 January 2018. This high rise has 2,082 tonnes of HISTAR® steel sections in its foundations, with the steel produced by ArcelorMittal Europe – Long Products. The use of our steel sections allowed the contractor to save both time and weight.

DUO comprises residences, offices, a hotel and retail space. It is designed by German-born Ole Scheeren, the architect behind the design of landmark projects such as the CCTV headquarters in Beijing, the MahaNakhon, Bangkok’s tallest skyscraper, as well as The Interlace, iconic residential development in Singapore and World Building of the Year in 2015.

Weight saving of 20% thanks to HISTAR®

ArcelorMittal contributed to the construction of the DUO Residences tower, which is still under construction. We supplied 2,082 tonnes of HISTAR® 460 steel sections produced in Differdange, Luxembourg, which were used to build the foundations of the tower using the top-down method.

What is the top-down method?

The top-down method is a composite method to build foundations. King post piles are put in the ground and while digging around them, slabs of concrete are put on top of them. At the same time, construction of the top structure starts. When arriving at the bottom, concrete is put around the king post piles for fire resistance. When the foundations of the building are completed, the building is already partially built, resulting in reduced construction time for the contractor.

The top-down method using our steel sections offers many advantages:

•     Weight saving of 20% compared to grade S355M (instead of using 2 sections in grade S355M, only one section in grade S460M/HISTAR® 460 was necessary)
•     Smallest hole to drill in the soil
•     Less fabrication work
•     No splicing needed
•     Fast to install

An impressive panorama of Singapore

Located in the centre of Singapore, in a neighbourhood that is home to historical sites and national monuments, the DUO project is composed of two towers, DUO tower (39 floors) and DUO Residences (49 floors). DUO is developed by M+S Pte Ltd, owned by Malaysia’s strategic investment fund, Khazanah Nasional Berhad and Singapore’s state-owned investment company, Temasek Holdings.

CapitaLand is the project manager of DUO.

Magnelis® brings a touch of nature to your facades

Vegetal exterior walls, or “green walls,” are a great way to bring nature to the facade of buildings and give them a unique look. Green walls are designed either as aesthetic elements for interior or exterior décor - sometimes as works of art using plants or as elements of urban ecology. For instance, a green wall is one of the elements that makes the facade of the Musée du quai Branly in Paris so unique.

French company Tracer, a pioneer of vertical walls and vertical gardens in France, is a regular customer of ArcelorMittal Downstream Solutions’ agency in Chalon-sur-Saône. For their creations, Tracer orders ArcelorMittal construction products such as rolled steel sheets or aluminium, and especially Magnelis®, a flagship product of ArcelorMittal Europe – Flat Products.

Magnelis®

Magnelis® is an ideal product for building the metal frame of green walls:

•    Its properties and particularly its high resistance to corrosion makes it perfect for environments with permanent humidity (the presence of plants implying biological and microbial activity and micro-organisms)
•    It meets the standards requested by Tracer, which contributes to their CSTB* approval

*CSTB: Centre Scientifique et Technique du Bâtiment (Scientific and Technical Center for Building)

Downstream Solutions delivers the Magnelis® steel sheets to Tracer, who then cut them to the right dimensions for their customers’ projects. Tracer also takes care of installing the sprinkling systems and the plants, selected with the project manager to meet the desired aesthetics thanks to a database of more than 300 plants.

About Tracer

Created in 1989, Tracer is a pioneer of vertical walls and vertical gardens in France. The company has a strong know-how in vegetal solutions with more than 17 000 m² of vegetal walls and facades created with their patented products (VertiFlore®, VertiBruit®). The company has a factory located in Dijon where all materials are manufactured.

They have realised green walls for many businesses such as shopping centres, office buildings, residential buildings, schools, supermarkets, and hotels.

Since the early 2000s, Grand Line has been working with organic coated steels from ArcelorMittal Europe – Flat Products for its range of roofing tiles and accessories. The products are used by Grand Line’s customers for the roofs of cottages and low-rise constructions. Today Grand Line is utilising ArcelorMittal’s Granite® HDX for its Quarzit range because it offers excellent performance in the harsh Russian climate.

Grand Line began buying Granite® HDX when its customers started demanding a high-performance roofing solution with a polyurethane coating. “At the time, another steelmaker was offering this solution so our customers were naturally interested,” explains Sergey Namestnikov, head of marketing. “We searched for a product that would offer the same outstanding colour and gloss retention and found Granite® HDX from ArcelorMittal for our Quarzit range.”

Colour selection suits local aesthetics

Granite® HDX is available in a wide range of colours and metallic shades, however, Grand Line uses a limited selection, notes Sergey Namestnikov: “From the Granite® HDX colour palette we mainly choose dark colours such as moss green, copper brown and chocolate brown, which ArcelorMittal colour-matches for us to ensure consistency. On top of this standard offer, we ask for special colours including copper which suit the aesthetics of our local market.”

In addition to roofing solutions, Grand Line creates metallic siding and corrugated profiles. “Many of these products are created with Access Standard and other steels from ArcelorMittal’s Granite® range including Standard, HD, Storm, and Deep Mat,” says Sergey Namestnikov. “And we make gutters out of Granite® Rain HDS.

Innovation days facilitate knowledge exchange

Grand Line has a stand where ArcelorMittal materials are tested in natural conditions to ensure their suitability for the Russian climate, notes Sergey Namestnikov: “This allows us to have a continuous exchange with ArcelorMittal about the corrosion tests, and to provide them with feedback from the end users of our products. Since 2014, we have held innovation days at least once a year to facilitate the feedback process. We are in contact with ArcelorMittal’s technical support teams on a regular basis for any immediate questions or issues.”

Grand Line

Founded in 1965, Grand Line has grown to become one of the largest producers of building materials for cottages and low-rise construction in Russia. The company employs more than 3,000 people at its seven plants in Russia. Grand Line’s Vorsino plant is one of the most advanced in Russia and utilises a range of technologies not found elsewhere in the country. Grand Line exports to every region of the country as well as to Belorussia, Kazakhstan, and Latvia.

The world’s most prestigious award programme for the circular economy, The Circulars, has highly commended ArcelorMittal for demonstrating leadership and innovation by applying circular economy principles to its business models.

By collaborating with internal experts, those from academia and its customers, ArcelorMittal is finding ways to make transformational changes to the way it does business, as it seeks to achieve its ambition of becoming a zero-waste company. Some of the ways it is doing this, acknowledged by the commendation, include:

• Partnering with technical and industry leaders to develop and scale up ground-breaking carbon capture and utilisation technology, resulting in products like Steelanol, a bio-fuel made from waste carbon monoxide, with the help of microbes. This high-grade ethanol will then be used for transportation and to make plastics. The company anticipates Steelanol could create 2000 direct and indirect jobs and generate an income of 300 million euro a year by 2025, while significantly reducing greenhouse gas emissions – 5 million tonnes worth a year by 2025.
• Manufacturing ECOCEM, a low carbon cement, from its slag and selling it directly to customers. In France alone, this practice has already reduced the cement industry’s CO2 emissions by nearly two million tonnes, and from 2018 onwards it is projected to further reduce those emissions by a further one million tonnes a year. Selling this by-product generates over 100 million euro in revenue each year.
• Paving more than 650 km of country roads across 20 Brazilian municipalities with over 1.5 million tonnes of Revsol and Revsol Plus.  These products, made from slag, a by-product of the steelmaking process, replace natural non-renewable resources such as gravel.
• Allocating additional resources to detailed life cycle assessment of its products and developing a new sustainability assessment tool.
• Designing innovative processes and products to maximise efficiency and minimise waste in its own production and those of its customers.
• Stretching product lifecycles by leasing sheet piles for short term projects, rather than selling them – and then leasing them again. The company’s comparative studies show reusing sheet piles has 86% less global warming potential than permanent steel sheet piles and 90% less global warming potential than a concrete retaining wall.
  Similarly, through the circular building, exhibited at the London Design Festival 2016, the company demonstrated the concept of steel reuse for entire steel structures, given they are designed, dismantled and reused with the circular economy in mind.
• Torrefing waste wood and using it to replace coal in its blast furnaces, harnessing and using energy that would otherwise have been lost. In doing so, the company expects to recycle two to four million tonnes of waste wood each year by 2025, saving it approximately 100 million euro a year.
• The Circulars 2018, an initiative of The World Economic Forum and The Forum of Young Global Leaders, run in collaboration with Accenture Strategy and given at the World Economic Forum’s Annual Meeting in Davos. The award recognises individuals and organisations from around the world who are making notable contributions to the circular economy.

Alan Knight, General manager, head of corporate responsibility and sustainable development said, “Being highly commended by the Circulars 2018, is a fantastic achievement and highlights how far we have come as a steel company to change not only the way we do things, but also the way we are perceived as a corporate citizen. We have long talked about the value steel brings to people’s lives and its unparalleled recyclability, but now we are finding ways to take those ideas further and become a zero-waste company by integrating circular economy principles into everything we do.”

Interest in the use of high strength steels (HSS) is growing rapidly in the global construction sector. That’s because high strength steels offer promising weight reductions, increased spans, and improved load-bearing capacity compared to alternative materials.

Benefits of using ArcelorMittal’s high strength steels for structural profiles

Cold-formed profiles made from HSS are used for many applications including roofs and facade structures, light steel framing, prefabricated modules, storage and racking systems, and silos. With new construction steel grades up to S550GD+Z, HSS offer profilers, installers and end users great potential for structural improvements. If the same thickness of steel is used, design stresses can be increased or longer spans can be achieved. Alternatively, the thickness of profiles can be reduced, resulting in significant weight savings which also reduce production and transportation costs.

European building codes and standards are being developed to include these new HSS grades. The following standards have already been revised:

• Eurocode 3, Parts 1-12 have been updated to allow the use of steel grades up to S700.
• EN 10346:2015 for continuously coated steel flat products for cold forming has been updated to include several new grades such as S390GD+Z, S420GD+Z, and S450GD+Z. New zinc-magnesium coatings such as Magnelis® have also been added.

A fruitful partnership between Hilti and ArcelorMittal: New self-drilling screws from Hilti increase performance

Early in 2017, Hilti and ArcelorMittal initiated a technical collaboration to improve the performance of self-drilling screws for HSS. The screws are typically used to fasten sandwich panels to the cold-formed profiles of building structures.

The collaboration between Hilti and ArcelorMittal has resulted in the development of the first worldwide portfolio of fastening elements to connect sandwich panels and HSS profiles (up to S450GD). The new screws are backed by a European Technical Approval (ETA-13/0179).

The technology combines a hardened carbon-steel drill tip and stainless steel shaft. The result is improved installation speed and long-term endurance in corrosive environments.

Other applications for the screws are being tested including long-span decking and racking. Once approved, they will enlarge the applications for these screws and enable one-step fastening of HSS profiles.

About Hilti

Founded in 1941 as a family company, Hilti now designs and manufactures leading-edge technology, software, and services to power the professional construction industry.

Hilti is a global organisation employing more than 25,000 people across 120 countries. The company offers a complete service package for your projects including design software, products and tools for onsite work, repairs, testing, and consultancy. Hilti is a one-stop shop for building, worldwide.

IBU (Institut Bauen und Umwelt e.V.) has published an Environmental Product Declaration (EPD) for single-sided road barriers made with high strength low alloy and structural steels coated in Magnelis®. The EPD covers barriers which are made from steel grades HX340LAD, HX420LAD, S250GD, or S350GD, with ArcelorMittal’s Magnelis® ZM310 metallic coating.

The EPD applies to one running metre of a single-sided barrier including the support post. The thickness of the steel ranges from 2.8 to 8.0 mm depending on the design.

The barriers covered by the EPD meet the H1W3A level of the EN 1317-2:2010 European standard for road restraint systems. H1 barriers are designed to contain a 10,000-kilogram vehicle travelling at 70 kilometres per hour. The EPD is based on data collected from ArcelorMittal’s mills in Bremen (Germany) and Ostrava (Czech Republic).

An EPD is an independent and transparent way of communicating about the environmental performance of a product or system. The content is derived from a life cycle assessment (LCA) and typically evaluates all phases of the product’s life including supply of the raw materials, production, and end-of-life recycling. The EPD also contains information about the energy use, efficiency, emissions, and waste generation during the product’s manufacture, service life, and recycling.

Bacacier is one of France’s leading manufacturers of steel roofing and cladding solutions for the building and construction sector. With an eye on constant innovation, Bacacier is always looking for new aesthetic steel solutions to enhance its range of products. Thanks to a close relationship with ArcelorMittal Europe – Flat Products, Bacacier was a key partner in the development of Granite® Quartz in France and is now incorporating it into their latest products.

Bacacier is constantly innovating its product range to bring the best steel solutions to its customers. Unlike many of its competitors, Bacacier creates products for both professionals and the fast-growing do-it-yourself (DIY) market.

A durable and attractive solution

Bacacier has recently created a new range of construction materials using Granite® Quartz from ArcelorMittal. “We are always looking for new finishes and Granite® Quartz was a good solution thanks to its look and feel, and scratch resistance,” explains Luc De Deygere, purchasing director of Bacacier. “Scratch resistance is very important – particularly for our roofing solutions.”

Bacacier was closely involved in industrial-scale trials of Granite® Quartz notes Luc De Deygere: “ArcelorMittal does not just sell us coils. We sit with their technical people and explain our needs. Together we can co-engineer products for the future. When ArcelorMittal first proposed the idea of Granite® Quartz, we immediately saw the potential of this durable and attractive solution.”

Although Bacacier has only recently introduced Granite® Quartz to its professional clients, sales are steady says Luc De Deygere: “It’s only been on the French market for a few months, so customers are still becoming aware of Granite® Quartz. But their initial reactions have been overwhelmingly positive. We see a bright future for Granite® Quartz as part of our portfolio.”

Bacacier’s Tuile R PRO system simplifies the construction process and comes with a 20-year guarantee.

Granite® Quartz comes in a range of colours which mimic traditional building materials including slate (Grey – QGY01) and terracotta (Medium Brown – QBR02).

ArcelorMittal Europe - Long Products Sections and Merchant bars has launched a new brochure about the optimal use of hot-rolled steel shapes in tall buildings.

This ArcelorMittal publication, focusing on high-rise buildings, was produced with the assistance and guidance of the Council on Tall Buildings and Urban Habitat (CTBUH), the world’s leading resource for professionals focused on the inception, design, construction and operation of tall buildings and future cities.

This publication highlights how structural steel can be used in tall buildings and directly references the Outrigger Design for High-Rise Buildings and Recommendations for Seismic Design Technical Guides developed by CTBUH Working Groups. The Life Cycle Assessment of Tall Building Structural Systems and Composite Megacolumns Research Reports, which were made possible through research grants provided by ArcelorMittal, are also discussed in this publication.

ArcelorMittal is launching the extended version of its Orange book, an essential aid for engineers in the design of steel buildings and structures.

Already including data about ArcelorMittal Europe – Long Products’ structural sections, the ArcelorMittal Orange book is now completed with information about ArcelorMittal Europe – Flat Products’ offer of cold formed and welded sections.

What is the Orange book?

The Orange book is a valuable profile calculation tool for engineers and metal structure designers. It allows them to find the best product according to the construction variables (type of sections, geometrical parameters, steel grade) and the building’s loads.
Thanks to the Orange book, it is possible to make calculations to:
-    Increase the range of a building
-    Make lighter structures thanks to high resistance steels
-    Increase the load bearing capacity

The Orange book is part of ArcelorMittal’s digitalisation strategy which involves the creation of specific internet tools for customers, developers and designers.
