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.”

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.

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.
