Granite®

Prepainted steel for buildings in corrosive environment


With its wide range of colors and shades along with the different textures, Granite® makes your project come true.

The aesthetics of this product makes it popular for roofing and cladding. As for its technical performance, Granite® is convincing with its robustness, durability and color stability. That is why its name is a reference to one of the most resistant minerals found in our natural environment – withstanding any type of corrosion.

Granite® is part of ArcelorMittal Flat Carbon Europe’s Nspired by Nature range and it is certified as a product not containing hexavalent chromium or heavy metals.

Apart from their appearance, the Granite® coatings offer exceptional technical advantages and respond to present and future environmental regulations. Within the Granite® collection various aesthetic and functional products were developed - find the coating that is best suited for your requirements!

Granite® product range by application

 

Granite® guarantee

By selecting Granite®, you make the choice of quality & sustainability for building  systems placed in outdoor conditions.

All our specifications are based on the requirements of the construction habits and regulations. The corrosion is ensured by a zinc substrate of minimum 200 grams per square meter. The surface performance is obtained by a performing paint layer of minimum 25 microns.

But as performance is more than only defining a specification, our products have been subjected to a battery of tests in the laboratory and at outdoor exposure sites. Only after a minimum of two years exposure with positive results we start placing news products on the market.

Furthermore, ArcelorMittal is involved in “on site quality inspections”. Our development team is inspecting continuously buildings erected several years ago to check how our products behave in real conditions.

By selecting Granite®, you make the choice of a certified quality.

All our products have been labeled with ECCA Premium® (quality and sustainability for prepainted metal) and are REACh compliant (Registration, Evaluation, Authorisation and Restriction of Chemicals), meaning free of Hexavalent chromium
(recognized as a human carcinogen) or heavy metals.
