Heavy plate


ArcelorMittal Europe – Flat Products offers heavy plate in weights up to 18-19 tonnes*, lengths up to 25-metres, and thicknesses ranging from 6 to 150 mm.

XCarb® recycled and renewably produced offers low carbon footprint

Our heavy plate can also be supplied via our XCarb® recycled and renewably produced route. The steel is produced from slabs made in an electric arc furnace (EAF) using almost 100-percent scrap and 100-percent renewable electricity. The result is heavy plate with a 65-percent lower carbon footprint than the same product made via the conventional steelmaking route. Read more

XCarb® green steel certificates reduce Scope 3 emissions

Alternatively, our heavy plate can be supplied with XCarb® green steel certificates. Like XCarb® recycled and renewably produced steels, the certificates enable customers to reduce their Scope 3 (supply chain) emissions. The CO2 savings, and corresponding volume of XCarb® green steel certificates, are assured by DNV, an independent expert in verification and assurance. The certificates comply with the Greenhouse Gas Reporting protocol and can be redeemed by ArcelorMittal’s direct customer, or the end customer for the product.

EPD available

An Environmental Product Declaration (EPD) for our heavy plate produced via the conventional blast furnace route is available. The EPD meets the EN 15804 European standard and can be downloaded here.

ArcelorMittal also released an EPD for our XCarb® recycled and renewably produced heavy plate. It can be dowloaded here.

Case studies


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.


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.


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.


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.
