The difference between Galvalume Steel Sheet&Galvanized Steel Sheet

The difference between Galvalume Steel Sheet&Galvanized Steel Sheet mainly lies in the difference of coating. The surface of galvanized plate is evenly distributed with a layer of zinc material, which plays the role of anode protection for the base material, that is to say, the alternative corrosion of zinc material protects the use of the base material, and only when the zinc is completely corroded can it hurt the base material inside.
 
The surface coating of the aluminized zinc plate is composed of 55% aluminum, 43.5% zinc and a small amount of other elements. The surface of the aluminized zinc coating has a honeycomb structure at the microscopic level, and the honeycomb composed of aluminum contains zinc. In this case, although the aluminized zinc coating also plays the role of anode protection, But on the one hand due to the reduction of zinc content on the one hand due to the zinc material by aluminum packaging is not easy to electrolyze so the role of anode protection is greatly reduced, so once the aluminum zinc plate is cut, cut off the edge of the basic loss of protection will soon rust, so the aluminum zinc plate should be cut as little as possible, once cut after the application of anti-rust paint or zinc rich paint to protect the edge, Can make the service life of the plate long.

Application

Galvalume Steel Coil is a kind of high - value anti - corrosion composite sheet formed by physical reaction of cold rolled sheet. It consists of 55% aluminum, 43.5% zinc, and 1.5% silicon. Spray on the surface of cold rolled plate, the substrate has a good protection. Most of them are used for the maintenance of the building roof and wall of steel structure. Now it also involves the frame of the electrical surface. Such as refrigerator, TV, microwave oven, washing machine and so on.
