55% Al-Zn Aluzinc Steel Coil 

PRODUCT DESCRIPTION 55% Al-Zn Aluzinc Steel Coil. The aluminum-zinc-coated steel coil is composed of aluminum-zinc alloy structure, which is composed of 55% aluminum, 43.4% zinc and 1.6% 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. The surface of the galvalume steel coil has a unique smooth, flat and gorgeous star flower, and the base color is silvery white. The special coating structure makes aluzinc steel coil have excellent corrosion resistance. The normal service life of the galvalume coil 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 production process of galvalume steel sheet in coil is simil…
