The grades of the steel substrates available, combined with the properties of the Granite® coating, make these products attractive alternatives that meet all the requirements of the construction sector.
The Granite® range combines all the requirements of the building sector in terms of solutions, aesthetic quality and properties such as flexibility, surface hardness, coating adhesion, corrosion and UV resistance etc.
Various types of paints, in a wide range of colours and surface finishes, can be used to coat the substrate.
ArcelorMittal offers these products in a wide range of standard colours.
The pre-painting process is environmentally friendly, economical and guarantees consistent product quality. The Granite® range is REACH compliant; it does not contain any of the substances like chromates and heavy metals.

Granite® products are in compliance with standard EN 10169.
The choice of the paint system depends on the end use and the environment. Several products are suitable for highly aggressive environments, such as urban and coastal environments, hot and humid overseas climates, sand storms etc.
The substrates used for these applications are galvanised steel or Optigal® (Zn-Al-Mg). For more information on the available metallic substrates and the technical properties of the different products, please consult the technical data sheets.
Please contact us for advice on the choice of the most suitable grade.
A temporary removable protective film can be applied on the top side, depending on the type of coating. Please contact us for further information.
Granite® products are available with a wide range of mechanical properties, depending on the substrate used and the intended application. See properties of the different substrates.
A1 in accordance with standard EN 13501-1, except for Granite® HDXtreme which is classified A2 - s1, d0.
Granite® products can be processed by cold forming and deep drawing without damaging the top surface. They can be joined using techniques such as clinching, riveting and adhesive bonding.
