- PRODUCT DESCRIPTION
-
Galvalume is an important alloy material that is often used in daily life. The aluminum-zinc-coated 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 ° C. The entire structure is composed of aluminum-iron-silicon-zinc, forming a dense quaternary An alloy of crystals.
Galvalume-galvanized steel coils have many excellent characteristics: strong corrosion resistance, which is three times that of pure galvanized coils; the surface has beautiful spangles, which can be used as building exterior panels.
The corrosion resistance of "galvalume steel coil" is mainly due to the protective function of aluminum. When the zinc is worn away, the aluminum forms a dense layer of aluminum oxide, which prevents the corrosion-resistant substances from further corroding the interior.
Aluminum-zinc alloy steel coils have good heat resistance and can withstand high temperatures of more than 300 degrees Celsius, which is similar to the high-temperature oxidation resistance of aluminized steel sheets. They are often used in chimney pipes, ovens, illuminators and fluorescent lamp shades.
The heat reflectivity of galvanized steel coil is very high, which is twice that of galvanized steel sheet, and people often use it as a heat insulation material.
Construction: roofs, walls, garages, soundproof walls, pipes, and modular houses, etc. Automobiles: mufflers, exhaust pipes, wiper attachments, fuel tanks, truck boxes, etc. Home appliances: refrigerator back panels, gas stoves, air conditioners, electronic microwave ovens, LCDs Frames, CRT explosion-proof belts, LED backlights, electrical cabinets, etc. Agricultural: pig houses, chicken houses, granaries, greenhouse pipes, etc. Others: thermal insulation covers, heat exchangers, dryers, water heaters, etc.Common surface treatment of galvanized steel coil:
