STEEL SPECIFICATION Product selector Choose the perfect solution for your project
A range of coated and uncoated steel for construction Steel Envelope offers the designer and specifier a unique range of steels to meet the most demanding of aesthetic, performance and environmental building requirements. Aesthetic: a wide range of colours available in satin, matt and deep matt; finishes ranging from spangled silver and reflective, to deeply textured, to gorgeous weathered patinas; unique patterns; tactile smooth interior finishes; bespoke designs to match the unique identity of your buildings. Performance: steels that deal with the extremes of temperature and weather; that deal with marine and other corrosive environments; that offer scratch resistance and self-healing properties; that can easily be formed in sub-zero temperatures; that perform well in high UV conditions with colours that last and retain their visual appeal with minimal maintenance. Environmental: steel is 100% recyclable, indefinitely, without quality loss; it is a major contributor to thermal efficiency and energy savings; it can be coated by paints with no heavy metal content, which minimise environmental impact.

The performance of organic coated steels Organic coated steel is produced by applying a paint coating to steel strips in a continuous manufacturing process compliant with EN 10169. This process is called coil coating. Coil coating is an industrial and highly efficient means of coating steel strip metals before fabrication of finished components, providing a highquality, uniform and reproducible surface finish. Coil coating represents the most efficient, the most reliable and the most environmentally-friendly way of applying a high-quality paint finish to metal surfaces and delivers products that are beautiful, versatile, durable and sustainable. The high quality of our coil coated ranges allows us to give excellent guarantee levels, many of which are automatic (applied once the product has been delivered). The properties of organic coated steel In our steel, ArcelorMittal is committed to perfecting the key features that play an essential role in the durability and aesthetics of the building: Corrosion resistance The optimum choice of metallic steel substrate plays an important role in the corrosion resistance of the final product (see 1 and 2, right). Based on more than 50 years of experience in the building sector across the entire range of European climates, we offer an extensive range of hot dip galvanised steel or equivalent metallic substrates which comply with EN standards and/or the regulations of national construction sectors. The UV resistance of the paint The right choice of the paint system and the minimum painting thickness depending on the environment contribute to the system integrity (see 3, right). The paint top layer (topcoat) gives the aesthetic effect. It filters UV radiation and protects the primer layer from photo-ageing by using the right pigments and plays an important role as a barrier to water and corrosive agents. As the topcoat is very often in contact with tools and subject to forces like friction and deformation, we ensure that our paints have sufficient mechanical properties and surface robustness to permit transport and forming operations. Flexibility and paint adhesion Flexibility and adhesion of the paint to the steel metallic substrate are vital during processing and forming operations. Respect for the environment Our Nature collection of organic coated paints are free of hexavalent chromium (Substances of Very High Concern included in the REACH European regulation Candidate List) compounds. Our products are heavy metal-free (no lead) in the steel metallic substrate, and in the paint and surface treatment layers. ArcelorMittal coils storage area Photography: Jeroen Op de Beeck 1.

Thanks to our know-how and expertise we can offer long-term guarantees on our steels for exterior applications - often up to 30 years. Reliable products Our steel products for construction are fully tested by our global R&D experts under extreme corrosion and weathering conditions, both in the laboratory and at outdoor exposure sites across the world. Independent testing Once tested internally, we commission further extensive testing by independent assessors and laboratories to achieve third party certification such as CSTB in France, BBA in the UK and many others, so that the products can be specified in complete confidence. Why invest in ArcelorMittal guaranteed products? Strong expertise in coil coating for more than 50 years Quality products, tested both in our laboratories and in the real environment Traceability Responsible sourcing Quality processes and expertise from manufacture to logistics and delivery Third party certification from national accreditation bodies Guarantees are granted automatically Please contact us if you want us to analyse your specific project and its guarantee potential. Transparency Our full legal text for the Granite guarantee is accessible to the public and visible on our website industry.arcelormittal.com/buildingguarantees ArcelorMittal s guarantees vary depending on the product family as well as the environment and application in which the product will be used. AUTOMATIC UP TO 30 YEARS GUARANTEE Clear and easy to understand, the exact conditions of our guarantees covering exterior applications, namely the Granite range, can be read in full on our website. Automatic guarantee For these guarantees, the administrative steps have been reduced to a minimum. No paper guarantee is issued but the guarantee applies automatically from the moment the product is delivered to the client. Long duration on a large geographical scope Long periods of guarantee are granted with top products like Granite HDX - up to 30 years against corrosion and non-peeling of the paint - depending on the area. Marine environments - example 1 In marine environments as little as 300 m from the sea, ArcelorMittal provides guarantees of 15 years against non-perforation of the base metal sheet and non-peeling of the paint film with Granite HDX on a metallic substrate of minimum Z275 or equivalent. environments - example 2 In strong UV environments we offer 15 years guarantee against non-perforation of the metal sheet and non-peeling of the paint film with Granite HDX on a metallic substrate of minimum Z225 or equivalent.
