Galvalume Steel Coil is composed of 55% aluminum and 43.4% zinc and 1.6% silicon by weight. The surface is characteristic of smooth, flat spangles. Special coating structure makes it has excellent corrosion resistance.
And,There are two kinds of GL(Galvalume Steel Coil):Anti-finger Print GL and Without anti-finger print GL.
Galvalume Steel Coil Specifications:
The Technical Requirements of Galvalume Steel Coil:
The corrosion resistance of " Galvalumed steel coil" is mainly due to the protection function of aluminum. When zinc is worn, aluminum forms a dense layer of alumina, preventing further corrosion of the corrosion-resistant material inside.
Galvalumed steel has good heat resistance and can withstand temperatures of more than 300 degrees.
Galvalumed steel, which is often used as an insulating material, has a high thermal reflectance, twice that of galvanized steel.
Since the density of 55% al-zn is smaller than that of Zn, the area of aluminum and zinc plated steel is more than 3% larger than that of plated steel with the same weight and the same thickness.
Galvalume Steel Coil Application:
1.Construction industry is mainly used to manufacture anti-corrosion industrial and civil building roof panels, roof grills, etc.;
2.Light industry uses it to manufacture home appliance casings, civil chimneys, kitchen utensils, etc.,
3.Automotive industry is mainly used to manufacture corrosion-resistant parts for cars, etc.
4.Agriculture, animal husbandry and fishery are mainly used for food storage and transportation, frozen processing tools for meat and aquatic products, etc.;
5.Commercial industries use is mainly used as storage, transportation and packaging equipment for materials.
6.Household appliances: refrigerators, washing machines, switch cabinet, air conditioning, microwave oven, bread machine, copier, vending machines, electric fans, vacuum cleaners, etc.
7.Transportation industry: car ceilings, car shells, car panels, tractors, trams, containers, highway walls, ship bays, etc. Other aspects: The color coated steel plate such as musical instrument casing, garbage bin, billboard, clock, photographic equipment, meter, etc. is made of hot-dip galvanized sheet, hot-dip aluminum-zinc plate, electro-galvanized plate, etc.
