PRODUCT DESCRIPTION
The surface of the GL Steel Coil Galvalume Steel coils have a unique smooth, flat and gorgeous star flower, and the base color is silvery white. The special coating structure makes aluzinc Steel Coils have excellent corrosion resistance. The normal service life of the galvalume coils can reach 25a, and the heat resistance is very good, which can be used in a high temperature environment of 315°C; the adhesion between the coating and the paint film is good, and it has good processing performance, and can be stamped, cut, welded, etc.; The surface conducts electricity very well.
The coating composition is composed of 55% aluminum, 43.4% zinc and 1.6% silicon respectively by weight. The production process of galvalume Steel Sheets in coil is similar to that of Galvanized Steel coils and aluminum-coated coils, which is a continuous fusion coating process. Galvalume-coated Steel Coils with 55% Al-Zn alloy coating have superior corrosion resistance when exposed to the same environment on both sides compared with galvanized steel coil of the same thickness. The 55% aluminum-zinc alloy coated Galvanized Steel Coil not only has good corrosion resistance, but also color-coated products have excellent adhesion and flexibility.
Since the Steel Plate will be oxidized and rusted when it is damp, it is necessary to add an anti-corrosion protective layer on the surface. Generally, the anti-corrosion coating is divided into hot-dip galvanized Zn and hot-dip galvanized Al-Zn (aluminum-zinc alloy composition is 55% aluminum) , 43.5% zinc and 1.5% silicon, referred to as 55% Al-Zn). The data shows that the comprehensive anti-corrosion ability of 55% galvanized galvanized is 4 times that of galvanized with the same thickness.
