Bare Galvalume
Galvalume in bare, finds wide application not only where corrosion resistance is required, but also where high temperature resistance, heat reflectivity, flexibility, formability and paintability
are required. The coating consists of Aluminium (55% in weight ratio, Zinc 43.5% in weight ratio and Silicon 1.5% in weight ratio.
These coating combines the barrier corrosion protection of aluminium with the sacrificial protection of zinc, giving the advantages of both metals.
