Substrate Type
Galvalume SteelComposition: Based on hot-dip galvanized steel sheet, the coating contains 55% aluminum, 43.5% zinc, and 1.5% silicon, forming a dense alloy layer.
Advantages: Corrosion Resistance: Aluminum forms an aluminum oxide protective film on the surface. The corrosion resistance is 3 - 6 times that of ordinary galvanized steel sheets, especially suitable for coastal areas with high salt spray and industrial areas with high pollution.
Strength and Toughness: Yield strength = 270MPa, elongation = 30%. It can withstand bending and impact without cracking, meeting the requirements of seismic design.
