Galvalume Metal Roof Board coating is composed of 55% aluminum, 43.4% zinc, and 1.6% silicon (by weight), which forms a multi-layer anti-corrosion barrier through a hot-dip process. Aluminum provides weather resistance, zinc sacrificial anode protects the steel base, and silicon enhances bonding strength, making its corrosion resistance 6-9 times higher than that of ordinary galvanized steel, and its service life can reach more than 50 years.

Zinc layer protection mechanism: Zinc sacrificial anode protects the steel base, aluminum provides a weather resistance barrier, and silicon enhances the bonding between the coating and the steel base.

Galvalume Metal Roof Board has become the material of choice for residential, commercial, industrial and renovation projects due to its light weight, weather resistance and design flexibility.
