The production technology of aluminized zinc plate is similar to that of galvani

The surface of aluminized zinc is characterized by smooth and rich star flowers, and the basic color is silver white. The coating consists of 55% aluminum, 43.4% zinc and 1.6% silicon. The production technology of aluminized zinc is similar to that of galvanized steel plate and aluminized plate. It is a continuous melting coating technology. When both sides of the coating are exposed in the same environment, the corrosion resistance of 55% Al Zn alloy coating is better than that of the same thickness galvanized steel plate. The coating of 55% Al Zn alloy has not only excellent corrosion resistance, but also excellent adhesion and flexibility.
The long-term corrosion resistance of metal coating products mainly depends on the dissolution rate of the coating and the thickness of the coating. The dissolution rate of zinc coating of galvanized steel is higher than that of 55% aluminum zinc alloy coating. Therefore, the service life of 55% Al Zn alloy coating is longer than that of galvanized steel plate.
Aluminum zinc plating has a silver white beautiful appearance similar to galvanized steel plate and excellent appearance and processability, especially in the steel plate, there are few cracks in the processing part, and its durability in the processing part is superior. In addition, the heat resistance is much better than that of galvanized steel plate, and the heat reflection is more than two times higher than that of galvanized steel plate. Uncoated products can be used in roof and partition board to save energy.
The coating of aluminum zinc gold plating layer has excellent adhesion, so it can be directly coated on advertising board and commonly used board without pretreatment such as weathering.
