Bridges

Heavy plate made from high-strength structural steel is the preferred material for bridge designers. The main applications for ArcelorMittal’s heavy steel plate are:

• Composite and box girders made of built-up welded sections and used in road, railway, and pedestrian bridges
• Bridge bearings including composite panels
• Bridge decks.

Case study – Unibridge^® links communities around the globe

French company Matière introduced their Unibridge^® concept in 2004. These patented structures can be shipped around the world and used as permanent or temporary crossings for vehicles and pedestrians. The solution uses ArcelorMittal’s S355K2+N and S460M high-strength steel plate which is known for its durability. This gives the Unibridge^® a 100-year design life. Read more

Wind energy

Heavy plate is extensively used in the tower of onshore and offshore wind turbines and related infrastructure such as offshore substations. Our heavy plate for the wind energy sector offers improved strength, workability, and weldability. It can withstand environmental loads, no matter how strong. The plate is supplied thermomechanically rolled or normalised, and shot-blasted and/or cut and bevelled on demand.

Case study – Substations transport offshore wind energy to the shore

Chantiers de l’Atlantique is known for building some of the world’s largest cruise ships. But did you know the company also builds substations for offshore wind farms? The company is using our heavy plate to create the vast structures which can withstand the harsh environment of the open ocean while transmitting clean electricity back to shore. Read more

Construction

Heavy plate is increasingly used in construction applications such as foundations and decking. High-strength heavy plate reduces the need for concrete as it can withstand severe case loads on its own ArcelorMittal’s ability to supply heavy plate in long lengths can also reduce construction time significantly.

Case study – New ArcelorMittal HQ takes shape in Luxembourg

ArcelorMittal’s new headquarters is taking shape in Luxembourg’s Kirchberg district. ArcelorMittal is making extensive use of heavy plate in the foundations of the building. The heavy plate is produced using the XCarb^® recycled and renewably produced (RRP) route. Made with almost 100% scrap steel and 100-percent renewable electricity, the carbon emissions of this product are over 60-percent lower than steel made via the conventional blast furnace route.

Shipbuilding

ArcelorMittal’s heavy plate has been successfully used as the base material to build dozens of ships: from small vessels to the world’s largest cruise ship ever built. Our shipbuilding grades are approved by all major certification bodies. They can withstand all conditions including very low temperatures – making them suitable for arctic and deep-sea vessels.

Case study – Service vessels from GONDAN Shipbuilders keep the energy flowing

When Gondan began building steel hulled vessels in the 1960s, they turned to a local mill for supplies. Over half a century later the link between that mill – now ArcelorMittal Gijon – and Gondan is as strong as the heavy plate the shipbuilder uses to create its offshore service vessels. These tough little ships are also at the forefront of the energy transition – with many equipped to run on hydrogen. Read more

The reliability and superior quality of our quarto plate offer improved strength, workability, and weldability. It is certified by all major certification bodies and can withstand even low temperatures which makes it suitable for many arctic and deep-sea vessels.
