Galvalume steel coil is an important alloy material often used in daily life. Galvalume steel coil is composed of aluminum-zinc alloy structure, which is composed of 55% aluminum, 43% zinc and 2% silicon solidified at a high temperature of 600℃. Its entire structure is composed of aluminum-iron-silicon-zinc, forming a dense quaternary structure. A crystalline alloy.
Characteristic:
Galvalume-coated steel coils have many excellent properties: strong corrosion resistance, 3 times that of pure galvanized coils; beautiful zinc flowers on the surface, which can be used as building exterior panels.
Corrosion resistance:
The corrosion resistance of "galvalume 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 resistance:
Aluminum-zinc alloy 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 oxidation resistance of aluminized steel sheets. It is often used in chimney pipes, ovens, luminaires and fluorescent lampshades.
Heat Reflectivity:
The heat reflectivity of galvanized steel coils is very high, twice that of galvanized steel sheets. People often use it as heat insulation material.
Economical:
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 coil is more than 3% larger than that of the plated steel coil.
use:
Construction: roofs, walls, garages, soundproof walls, pipes, modular houses, etc.
Cars: 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 use: pipes for pig houses, chicken houses, granaries, greenhouses, etc.
Others: Precautions for use of thermal insulation covers, heat exchangers, dryers, water heaters, etc.
