Is it not clay roof? Not concrete? Metal!? No way!

Carefully selected stonegranules provide an excellent surface coverage and attractive natural looking and lasting colours for corrosion-resistant metal GERARD roofing tiles. Coloured granules are produced from the crushing of an opaque silico-aluminous metamorphic rock.

The coloration layer on the base particle is a hard coating based on mineral binder and mineral pigments cured at app. 500 0 C. It provides long lasting performance for the ageing on the roof. Carefully selected heat resistant and UV stable pigments possess attractive colours and offer colourfast coating system.
