Corrosion resistance
All solid and metallic colours surpass requirements of RC5 as per EN 10169:2009 proving outstanding corrosion resistance for external building cladding systems.
Natural weathering
Natural weathering testing is an essential part of testing the corrosion resistance of a pre-finished steel product. Colorcoat Prisma® has undergone a comprehensive programme of testing in key weathering climates around the world.
Exposure sites were chosen in order to provide the full spectrum of weathering zones from equatorial and tropical climates to urban, rural, industrial and coastal locations.
