Granite® products are in compliance with standard EN 10169.
The substrates used for these applications are galvanised steel or galfan. Substrates with Zn-Al-Mg metallic coatings are also available for Granite® Standard and Granite® HD. 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 technical properties are summarised in the table below. 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.
Recommendations for use
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.
