Galvalume-coated steel sheets have many excellent properties: strong corrosion resistance, 3 times that of pure galvanized sheets; beautiful zinc flowers on the surface, and can be used as building exterior panels.
Corrosion resistance The corrosion resistance of "galvanized steel coil" is mainly due to the protective function of aluminum. When zinc is worn, aluminum forms a dense layer of aluminum oxide, preventing corrosion-resistant substances from further corroding the interior.
Heat-resistant aluminum-zinc alloy steel plate has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius. It is very similar to the high-temperature oxidation resistance of aluminized steel plates. It is often used in chimney pipes, ovens, luminaires and fluorescent lampshades.
Thermal reflective galvanized steel sheet has a very high heat reflectivity, twice that of galvanized steel sheet. People often use it as heat insulation material.
Economical efficiency: Because the density of 55% AL-Zn is smaller than that of Zn, when the weight is the same and the thickness of the gold plating layer is the same, the area of the galvanized steel plate is more than 3% larger than that of the plated steel plate.
Usage Construction: roofs, walls, garages, soundproof walls, pipes and modular houses, etc. Automobiles: mufflers, exhaust pipes, wiper accessories, fuel tanks, truck boxes, 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 uses: pig houses, chicken houses, granaries, greenhouse pipes, etc. Others: thermal insulation covers, Heat exchanger, dryer, water heater, etc.
Precautions for use and storage: It should be stored indoors such as a warehouse, keep it dry and ventilated, and do not leave it in an acidic climate for a long time. When storing it outdoors, it must be protected from rain to avoid oxidation stains caused by condensation. Transportation: To avoid external impact, SKID should be used to support steel coils on transportation vehicles to reduce stacking and take rainproof measures. Processing: When GNEE is sheared, the same lubricant as the aluminum plate must be used. When drilling or cutting galvanized steel sheets, scattered iron filings must be removed promptly.
