ArcelorMittal would like to invite you to a webinar - Addressing the Climate Emergency: ArcelorMittal's low embodied carbon steel making strategy for low embodied carbon buildings. It will be hosted by Walter Swann, Steligence® construction engineer in the UK. The webinar will be in English and will take place on the 9 July at 12.30 (UK time).

The climate emergency and low carbon building solutions in steel as an answer

The climate emergency has brought into sharp focus the impacts of the built environment, and it is incumbent on designers to make design choices that are right for the planet. After making the choice to build, material selection inevitably follows and close collaboration with the supply chain is critical to making informed choices.

In response to the climate emergency, design guidance in the UK is emerging that introduces embodied carbon targets that progressively reduce in line with the Paris Agreement. As designers embrace the challenge of low carbon design, ArcelorMittal has taken on the challenge of low carbon steelmaking and low carbon building solutions in steel.

Due to the coronavirus pandemic, World Expo, like other world events, has been postponed. The event will now take place from 1 October 2021 to 31 March 2022 in Dubai, UAE. Called Expo 2020 Dubai, it will be the first World Expo ever hosted in the Middle East, Africa, and South Asia (MEASA) region. Expo 2020 Dubai is expected to attract 25 million visitors, and 190 nations have already confirmed their participation including Luxembourg with a 2100 m2 pavilion built with ArcelorMittal Europe – Long Products’ steel.

Steel from Belval and Differdange

ArcelorMittal was selected to supply the steel products for the construction of the building’s structure. The 170 tonnes of hot rolled structural steel shapes from the IPE and HE European size series were made in the Luxembourg mills of Belval and Differdange - in electric arc furnaces fed with recycled scrap as raw material. This is today’s most energy and resource preserving production route. As a natural key advantage of steel, the structural components were designed with mechanically fastened connections. At no extra cost, this solution allows for the economical disassembling, transportation, and reassembling of the pavilion for its next-use life.

A breathtaking design inspired by its nation

The pavilion is inspired by its nation: small and ambitious, intriguing and reassuring, and above all generous and open. The overall theme is ‘Opportunity,’ reflecting the country’s history, its present, and its future. The overall shape of the pavilion resembles a Möbius loop, where the twisting of a ribbon yields one single surface with no beginning and no end expressing infinity and, in particular, symbolising the circular economy. The face of the ribbon transiently serves as floor, wall, and ceiling thereby allowing a multifaceted scenography from the starting point to the top floor.

The visitors’ experience begins in the entrance area. As a kind of red carpet, a wide ramp between the inside and the outside skin of the building invites you on a journey of discovery via a gently sloped path to the next floor. It enthrals the visitors as they merge with the pavilion’s exhibition, which in a natural an interactive way displays a series of visuals featuring the country and its people.

The ground floor mainly accommodates the gift shop, restaurant, and the visitor’s ramp to the first floor. The first level hosts a multi-functional area for receptions and conferences, as well as the ramp guiding visitors without interruption towards the top. The second floor, the highest point, is dedicated to an exhibition of Luxembourg’s space economy.

To reach the earth again, a visitor has three options: taking the stairs or the lift are the conventional options, but a slide winding through the picturesque green patio is the fun one.

ArcelorMittal Rodange has sent out the first shipment of curved rails from our new rail transformation centre. A product of the new in-house downstream facility, this marks the start of a win-win operation for ArcelorMittal Europe – Long Products.

A one-stop shop for customers

ArcelorMittal Rodange produces grooved rails, light rails, and crane rails. In the past, many of these were processed by external sub-contractors.  Now, with the creation of our in-house downstream facilities, the service centre will enable the Rodange plant to act as a one-stop shop for customers, offering full solutions performance and reliability advantages.

The service centre, located in mill hall C (formerly the rebar mill), will deal mainly with grooved rails and to a lesser extent with light rails and crane rails. In addition, this will develop the access to the tram rail market and lead to further opportunities for downstream operations.

What services are on offer with the new service centre at ArcelorMittal Rodange?

In the first phase, the service centre will offer the following finishing services:

•    drilling (fish plating is done directly by the mill; the service centre will provide tie bar drilling)
•    bending (only for grooved rails)
•    straightening
•    cutting

More services are planned for a later phase.

What are the benefits for the customer of ArcelorMittal Rodange?

•    one single contact
•    ArcelorMittal warranty provided
•    packaging options
•    the possibility to group standard rails with complex finished rails - ‘transformed rails’ versus ‘rolled’ rails
•    increased flexibility and reduced lead time which leads to better service

Since the beginning of operations in March 2020, more than 1000 tonnes of products with special finishing have been collected.

The French company Matière first introduced its Unibridge® concept in 2004. Today these patented structures are shipped around the world where they are used as permanent or temporary crossings for vehicles and pedestrians. Thanks to their modular nature and ease of construction, the Unibridge® is particularly popular in remote regions where materials and skilled workers are hard to find. The solution uses ArcelorMittal’s S355K2+N and S460M high strength steel plates which are known for their durability, giving the Unibridge® a 100-year design life.

Close cooperation with ArcelorMittal

“The close cooperation between ArcelorMittal Europe – Flat Products and ArcelorMittal Projects, together with the quality of the plates produced in ArcelorMittal’s mill in Gijón, Spain guarantees the best level of service for Matière,” says Michaël Regal, Account Manager for Matière at ArcelorMittal Projects.

Since 2018, heavy plates from our Gijón mill have been successfully delivered to Matière and its subcontractors in France, Belgium, and Portugal. “When a very short lead time is required, we are in the position to offer a delivery in less than a week at any Matière yard thanks to our own stock of plates, beams, and tubes,” says Michaël Regal.

Designed for remote and developing regions

The Unibridge® was initially developed as a solution for the military but was never adopted. Matière immediately saw the potential of the solution in developing countries and remote locations as Hervé Blanc, Deputy General Manager of Matière, explains: “These areas typically require many bridges, but there is a lack of resources and skills to produce them.”

Ease of transport and construction in remote areas was a key consideration in the early design phase notes Hervé Blanc: “We developed a structure that does not require welding on site, and which can be assembled without heavy lifting devices. In some cases, the girders can be offloaded and pushed into place with an excavator, or sometimes by the truck that delivered them. It takes around five days to install a typical two-lane (nine-metre wide) bridge that is 40 metres in length.”

The only preparatory work that needs to be done is preparing the bridge’s abutments. That can be done by an onsite partner who can complete the work while the bridge is being manufactured and shipped.

Simple design makes transport simple and efficient

Matière adapted the design to ensure two of the box girders which form the basis of the Unibridge® could fit into a standard shipping container. “Our box girders are 11.4 metres in length, ensuring two can fit into each container,” says Hervé Blanc. “The girders can be pinned on site to create a maximum length of 60 metres. But if you include piles, you can extend the length of the bridge significantly. We’re currently constructing a Unibridge® in the Philippines which will be four kilometres long. There is no limit on the width of the Unibridge® as the box girders can be simply linked with spacers.”

Weight saving with S460M

Another consideration was keeping the weight of the container below 25 tonnes. “Thanks to the use of ArcelorMittal grades such as S460M, weight is not an issue,” says Hervé Blanc. “In the beginning we constructed the entire bridge from S355, and a typical box girder weighed 12 tonnes. Today we are using more S460M, and the average weight is 10 tonnes, a saving of almost 20 percent. Now we are looking at replacing the S355 with S460M from ArcelorMittal to achieve even greater weight savings. That will reduce the cost of transporting and installing the bridges.”

Low maintenance steels extend bridge life

One of the key advantages of ArcelorMittal’s steels is that they don’t need a lot of maintenance as Hervé Blanc explains: “ArcelorMittal’s steels are very tough! The bridge simply needs a fresh coat of paint every 15 to 20 years to protect it. In some areas we recommend a C5 paint system due to the marine environment.”

A sustainable solution thanks to steel

As the Unibridge® is prefabricated, there is no waste produced on site. All scrap steel produced in Matière’s factories is recycled or reused. The sustainability of the solution is further enhanced as it can be transported by ship from Matière’s plants in Europe.

The bridges themselves can be fully recycled at the end of their life or disassembled and reconstructed in another location. “The company which is building a traffic deviation around Strasbourg, France is renting two of our Unibridge® solutions to divert traffic around the roadworks,” says Hervé Blanc. “They will be in place for two years before they are dismantled and reassembled in another location.”

To date, Matière has installed over a thousand Unibridge® solutions in more than 35 countries around the world. “The introduction of the Unibridge® in 2004 was the beginning of Matière’s success story,” says Hervé Blanc. “But every Unibridge® is also a human success story. They can cut a journey that normally takes a day, to just an hour. This dramatically changes the way people in remote areas live and interact.”

About Matière

Matière was founded in 1932 and is still a family-run company. The business operates three plants in France and one in Belgium. All the plants produce components for Matière’s bridge business. In addition to the Unibridge®, Matière produce reinforced and prestressed concrete bridges, metal bridges, and composite structures which use both metal and concrete. The company is also involved in the repair of concrete and metallic bridges. Around 65 percent of its bridges are exported outside Europe.
