Galvalume steel coils/aluzinc/zincalum has smooth, flat and gorgeous star flower surface, and the base color is silver-white. The special coating structure makes it have excellent corrosion resistance. The normal service life of the aluminum-zinc plate can reach 25a, and it has good heat resistance and can be used in a high temperature environment of 315°C; the adhesion of the coating and the paint film is good, and it has good processing properties, and can be punched, cut, welded, etc.; The surface conductivity is very good.
The surface coating of thegalvalume/ aluminized zinc coils is composed of 55% aluminum, 43.5% zinc and a small amount of other elements. The surface of the aluminized zinc coating is a honeycomb structure under the microscopic view, and the "honeycomb" made of aluminum contains zinc. In this case, although the aluminum-zinc coating also plays the role of anode protection, on the one hand, due to the reduction of zinc content, on the other hand, the zinc material is wrapped in aluminum and is not easy to electrolyze, so the role of anode protection is greatly reduced. Therefore, once aluminum is plated The zinc plate is cut, and it will rust soon when the cut edge is basically lost and protected. Therefore, the aluminum-zinc plate should be cut as little as possible. Once cut, the edge can be protected by applying anti-rust paint or zinc-rich paint. Longer service life of plates.
Galvalume steel coils and steel sheets applications:
Construction: roofs, walls, garages, soundproof walls, pipes and modular houses, etc.
Automobile: muffler, exhaust pipe, wiper attachment, fuel tank, truck box, etc.
Home appliances: refrigerator back panels, gas stoves, air conditioners, electronic microwave ovens, LCD frames, CRT explosion-proof belts, LED backlights, electrical cabinets, etc. Agricultural: pig houses, chicken houses, granaries, greenhouse pipes, etc.
Others: Thermal insulation cover, heat exchanger, dryer, water heater, etc.
