1. Heat reflectivity: The heat reflectivity of aluminum-galvanized steel plate is very high, which is twice that of galvanized steel plate, and people often use it as a heat insulation material.

2. Heat resistance: Aluminum-zinc alloy steel plate has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius, which is very similar to the high temperature oxidation resistance of aluminized steel plate, and is often used in chimney pipes, ovens, illuminators and fluorescent lamp shades. Corrosion resistance: The corrosion resistance of aluminum-galvanized steel coil is mainly because of aluminum, aluminum's protective function. When zinc is subjected to abrasion, aluminium forms a dense layer of alumina that prevents corrosion-resistant substances from corrosively corroding the interior.

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

4. The easy-to-paint aluminum-zinc sheet has excellent adhesion between the paint and the paint, and can be painted without pretreatment and weathering. The coating adhesion of the gold plating layer of aluminum-galvanized steel sheet has excellent adhesion, so it can be directly applied to advertising boards and general plates without pre-treatment such as weathering.

5. Aluminum-galvanized steel sheet has a gorgeous silver-white surface.

6. Aluminum-galvanized steel sheet has similar processing performance and spraying performance to galvanized steel sheet.
