Good corrosion resistance, 3 times that of pure galvanized sheet; with beautiful spangles on the surface, it can be used as building exterior panels.
The corrosion resistance of "aluminized zinc steel coil" is mainly due to the protective function of aluminum and aluminum. When zinc is worn, aluminum forms a dense layer of aluminum oxide, preventing corrosion-resistant substances from further corroding the interior.
Aluminum-zinc alloy steel plate has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius. It is similar to the high-temperature oxidation resistance of aluminum-plated steel plate. It is often used in chimney pipes, ovens, illuminators and fluorescent lampshades.
The heat reflectivity of galvanized steel sheet is very high, which is twice that of galvanized steel sheet. People often use it as a material for heat insulation.
Because the density of 55%AL-Zn is lower than that of Zn, the area of galvanized steel sheet is more than 3% larger than that of coated steel sheet with the same weight and the same thickness of gold plating.
The main purpose
Construction: roofs, walls, garages, soundproof walls, pipes and modular houses, etc.
Car: muffler, exhaust pipe, wiper attachment, fuel tank, truck box, 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 house, chicken house, granary, greenhouse pipe, etc.
Others: thermal insulation cover, heat exchanger, dryer, water heater, etc.
Precautions for use
Storage: It should be kept indoors in warehouses, etc., kept dry and ventilated, and do not store in acidic climate for a long time. When storing outdoors, it is necessary to prevent rain to avoid condensation and oxidation stains.
Transportation: To avoid external impact, SKID must be used to support steel coils on transportation tools to reduce stacking and take rain-proof measures.
Processing: When cutting, use the same lubricating oil as the aluminum plate. When drilling or cutting aluminized zinc steel sheet, the scattered iron filings must be removed in time.
