Material Introduction
GALVALUME STEEL
All San-gobuild® roof products are manufactured from alu-zinc steel which have shown in tests to last 6-9 times longer than ordinary galvanised steel roofing products.
STONE CHIPS
All San-gobuild® roof tiles are coated with natural stone chips, volcanically formed and taken from quarries in French. These coatings add natural beauty to the roof and a hard layer of protection from the weather. Being of natural stone, the vibrant colour is protected against the extreme UV of the African sun and will never change.
Stone Granule --- Sintering VS Dyeing
