Product Description
Galvalume steel strip is composed of 55% aluminum, 43.4% zinc and 1.6% silicon, cured at 600°C. The corrosion resistance of galvanized steel is 2-6 times better than that of hot-dip galvanized steel, which is achieved by the combination of the sacrificial protection of zinc and the barrier protection of aluminum.
