The coating composition of the aluminum-zinc plate is 55% aluminum, 43.4% zinc, 1.6% silicon by weight.
Aluminum zinc plating steel plate has many excellent characteristics: strong corrosion resistance, 3 times of pure galvanized sheet; beautiful zinc flower on the surface, which can be used as building exterior board.

Aluminum zinc alloy steel plate has good heat resistance, can withstand high temperature of more than 300 degrees Celsius, similar to the high temperature oxidation resistance of aluminum plated steel plate, it is often used in chimney tube, oven, illuminator and fluorescent lamp shade.
