Fingerprint resistant GL steel sheet is an alloy coated steel sheet widely used in many fields such as building materials, home appliances, automobiles, environment, machinery, and ships. The galvanized steel sheet is covered with aluminum-zinc alloy on the surface of the steel sheet. Gl Coils Galvalume Steel Coils SGCC is composed of 55% aluminum, 43.5% zinc and 1.5% silicon solidified at a high temperature of 600°C. The entire structure is composed of aluminum-iron-silicon-zinc, forming a dense An alloy-coated steel plate of quaternary crystal.

Fingerprint resistant GL steel sheet 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 aluminum-plated steel plate. It is often used in chimney tube, oven, luminaire and fluorescent lampshade.The heat reflectivity of galvalume steel sheet is very high, which is twice that of galvanized steel sheet. People often use it as a material for heat insulation.Ordinary hot-dip galvanized products usually use temperature not exceeding 230 degrees, 250 degrees will change color, and aluminum-zinc plate can be used in an environment of 315 degrees without changing color for a long time. In an environment of 300 degrees for 120 hours, the color change of Baosteel's heat-resistant passivated galvanized steel sheet is much lower than that of aluminum and aluminized sheets.
