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 […]
