The surface of aluminum zinc coated steel plate has a unique smooth, flat, and gorgeous zinc flower, with a silver white base color. The coating composition is composed of 55% aluminum, 43.4% zinc, and 1.6% silicon by weight. 

The production process of aluminum zinc coated steel plate is similar to that of galvanized steel plate and aluminum plate, both of which are continuous melt coating processes. The weight ratios of the coating composition combination are aluminum accounting for 55% (surface capacity ratio of 80%), zinc accounting for 43.4%, and silicon accounting for 1.6%. Therefore, this product can best utilize the long-term corrosion resistance and heat resistance of aluminum and the galvanic corrosion effect of zinc.
