Galvalume steel is an important alloy material often used in daily life. The galvanized steel sheet is composed of aluminum-zinc alloy structure, which is composed of 55% aluminum, 43.5% zinc and 1.5% silicon solidified at a high temperature of 600℃. Its entire structure is composed of aluminum-iron-silicon-zinc, forming a dense quaternary crystal. Of an alloy.
Characteristics of Galvalume
Hot-dipped Galvalume Steel Coil has many excellent characteristics: strong corrosion resistance, 3 times that of pure galvanized sheet; beautiful spangles on the surface, which can be used as building exterior panels.
Corrosion resistance:
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, which prevents corrosion-resistant substances from further corroding the interior.
Heat resistance:
Hot-dipped Galvalume Steel Coil has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius. It is very similar to the high temperature resistance of aluminized steel plate. It is often used in chimney pipes, ovens, luminaires and fluorescent lampshades.
Heat reflectivity:
The heat reflectivity of Hot-dipped Galvalume Steel Coil is very high, twice that of galvanized steel sheet, and people often use it as a material for heat insulation.
Economical:
Because the density of 55% AL-Zn is lower than that of Zn, the area of the galvanized steel sheet is more than 3% larger than that of the coated steel sheet when the weight is the same and the thickness of the gold plating layer is the same.
Application of Hot-dipped Galvalume Steel Coil
use
The main uses of galvanized products are in two aspects. One is the shell and box of other electrical equipment used in electrical switch cabinets; the other is galvanized steel roofing for steel structure buildings, because of its good anti-corrosion and anti-corrosion properties. In many areas with heavy industrial pollution, aluminum-zinc color panels or aluminum-zinc fingerprint-resistant light panels are directly used on walls or roofs.
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.
