A. Heat reflectivity： 

The heat reflectivity of aluminum-zinc plated steel sheet is very high, twice that of galvanized steel sheet, and people often use it as a thermal insulation material.　　

B. Heat resistance ：

Aluminum-zinc alloy steel plate has good heat resistance, can withstand a high temperature of more than 300 degrees Celsius, and the high temperature oxidation resistance of aluminized steel plate is very similar, often used in chimney tubes, ovens, illuminators and fluorescent lampshades. Corrosion resistance: The corrosion resistance of aluminum-zinc plated steel coils is mainly because of the protective function of aluminum, aluminum. When zinc is worn, the aluminum forms a dense layer of alumina, preventing corrosion-resistant substances from further corroding the inside.　　

C. Economy: 

Because the density of 55% AL-Zn is smaller than that of Zn, the area of aluminum-zinc plated steel sheet is more than 3% larger than that of the plated steel plate under the same weight and the same thickness of the gold plating layer.　　

D. Easy to paint：

There is excellent adhesion between the aluminum-zinc plated sheet and the paint, and it can be painted without pretreatment and weathering.
