The hot-dip alloy coating of aluminum-zinc steel sheet contains 55% aluminum, 43.5% zinc, and 1.5% silicon, effectively combining the strength of steel, the corrosion resistance of aluminum, and the sacrificial protection capability of zinc for edges and gaps. Under similar conditions, the lifespan of an aluminum-zinc steel sheet with the same coating thickness is approximately four times that of a galvanized steel sheet. Aluminum-zinc steel sheet is a cost-effective product, with a price significantly lower than stainless steel or aluminum sheets, while boasting an aesthetically pleasing, bright silver-gray appearance.
