Made of steel

Our steel is used in buildings around the world, from tall towers to petrol refineries, from airports to railway stations and from shopping malls to residential houses. ArcelorMittal also supports car manufacturers through the different stages of a vehicle’s lifecycle. We are a technology leader in advanced high-strength, galvanised and coated steels – products that are used in the manufacturing of cars, vans and trucks. About one fifth of the global car production is made from ArcelorMittal steel, and we have an industrial presence in 22 countries spanning four continents.

ArcelorMittal’s steel has been used in famous landmarks around the world, including the new 1WTC in New York City, the Grand National Theatre of China in Beijing, the new Reichstag in Berlin, Germany, and the world’s first-ever zero emission polar research station, Princess Elisabeth Antarctica. Sporting venues around the world have been built with ArcelorMittal steel, from Johannesburg’s Soccer City to the Cape Town Stadium, both used for the 2010 World Cup in South Africa, to the Wembley Stadium in London

We produce a wide range of construction solutions including rebar, beams, bridge girders, flooring, steel fibres, roofing, cladding and walling, as well as our creative façades Arguin, Coques MD, Caiman, Ecaille and Gascogne. We also supply complete construction solutions, such as GlobalFloor® flooring, Styltech® residential Light Steel Frames and Angelina™ cellular beams.

We are part of the international team contributing to the Mose (Modulo Sperimentale Elettromeccanico) project to protect Venice from flooding at periods of high water. ArcelorMittal steel is being used to build the gates that will close the three inlets to the lagoon during times of high water, preventing the Adriatic Sea from entering the historic city.

High-strength steel for low-carbon construction

Steel is also playing an important role in building a sustainable future. ArcelorMittal’s high-strength steel grades (Histar®) for the construction industry combine reduced product thickness, very high-yield strength, superior toughness at low temperatures and outstanding weldability. These characteristics satisfy the needs of the construction industry for light and economical structures that meet both safety and sustainability criteria.

Histar® steels also reduce carbon dioxide (CO2) emissions. Substituting Histar® for regular steel achieves a CO2 reduction of around 30% in steel columns and around 20% in steel beams. The 50,000 tonnes of Histar® we produce each year represent a saving of 14,000 tonnes of CO2, which is the same as the annual emissions of around 4,000 cars.

Looking to the future, ArcelorMittal’s research and development team is developing even stronger steel. Histar® Grade 70 aims to exceed the current 460 model in every aspect. This means more weight savings – and more CO2 savings – for steel structures.


In 2011 ArcelorMittal’s automotive division generated $14.2bn in revenues and delivered 13.4 million tonnes of flat steel. We have a global reach, with a presence in South Africa, Europe, North America and Latin America. We are also present in India, Turkey and China via joint ventures, and in Japan via an alliance with NSC.

With a global presence in steel production and a network of 11 research centres, we aim to support our clients through different production stages, from a vehicle’s design phase through to mass production and after-sales service. More than half of our investment in product research and development (R&D) is allocated to the automotive industry, and we have five laboratories that are dedicated fully or partly to R&D for the automotive market, in East Chicago in the US, Hamilton in Canada, and Maizières, Montataire and Gandrange in France. Our R&D engineers work with carmakers throughout the lifecycle of their products to develop automotive steels that are stronger yet lighter than existing materials. We also develop new, cost-effective coatings to improve corrosion resistance, paint appearance and application processes.

Our presence in different regions also gives us valuable insight into new market trends. For example, ArcelorMittal provides steel solutions for low-cost cars and engine powertrains to meet changing customer and market needs.

We anticipate that regulatory and customer expectations for lightweight cars will rise in the future. Working closely with our automotive partners, we have developed S-in motion, a set of automotive steel solutions to make cars lighter – without compromising safety – and, in turn, reduce their carbon emissions.

With our current catalogue of automotive products, we support carmakers in optimising weight and cost, while reducing carbon emissions and, crucially, ensuring that stringent safety standards are met.
