Hot-dip Aluzinc Gavalume Steel Coil，thickness:0.14-1.5mm,width:600-1250mm,coating mass:40-275g/m2.Surface treatment methods: anti-finger print, oiled, oiled and chromated, passivated.Scopes of application: household appliance, building materials, automobi
The surface of the galvalume steel coil has a unique smooth, flat and gorgeous star flower, and the base color is silvery white. The special coating structure makes it have excellent corrosion resistance. The galvalume steel coil has good heat resistance and can be used in a high temperature environment of 315°C; the coating of the cold rolled steel coil has good adhesion to the paint film, and has good processing performance, and can be stamped, cut, welded, etc.; The surface of coil rolled galvalume steel coil is very conductive.
The coating composition of cold rolled steel coil consists of 55% aluminum, 43.4% zinc and 1.6% silicon by weight. The production process of galvalume steel coils is similar to that of galvanized steel coils and aluminum-coated coils, both of which are continuous melting plating processes. Compared with galvanized steel coils of the same thickness, 55% galvalume-coated galvalume steel coils have superior corrosion resistance when both sides are exposed to the same environment. The 55% aluminum-zinc alloy coated galvalume steel coil not only has good corrosion resistance, but also color-coated products have excellent adhesion and flexibility.
According to the processing method, we divide galvanized steel into the following categories:
1.Hot-dip Galvanized Steel Coil
As the name implies, hot-dip galvanizing is immersing the cleaned iron sheet into the molten zinc bath at about 500 degrees to form a zinc layer. It is the most commonly used method. It has some advantageous features:
1) The entire steel surface is uniformly covered with a zinc layer, even the corners, hollows, etc. so that the steel sheet is fully protected.
2) The cost of hot-dip galvanizing is cheap.
2. Electro-galvanized Steel Coil
Electro-galvanizing is a process of applying a layer of zinc to steel through electroplating, with a saline anode and steel conductor. It is able to enhance the corrosion and heat resistance of steel. Also, it makes steel sheets more good-looking.
Galvalume steel coil's unique protective characteristics and economical price point make it ideal for:
Construction: roofs, walls, garages, sound insulation walls, pipes and prefabricated houses, etc.;
Automobile: mufflers, exhaust pipes, wiper accessories, fuel tanks, truck boxes, etc.;
Home appliances: refrigerator back panel, gas stove, air conditioner, electronic microwave oven, LCD frame, CRT explosion-proof belt, LED backlight, electrical cabinet, etc.;
Agricultural use: Pig houses, chicken houses, granaries, greenhouse pipes, etc.;
Others: heat insulation cover, heat exchanger, dryer, water heater, etc.
