Bright Zero spangle GI Galvanized G90 1.0mm strips slitting steel coils for Light Steel Keel Frame
Hot-dip galvanised strips are long, narrow steel sheets, cold- or hot-rolled, with varying degrees of coating (zinc, aluminium) as the raw material. Hot-dip galvanising offers the advantages of a uniform coating, strong adhesion and long service life.
The hot-dip galvanised steel strip substrate and the molten coating solution undergo a complex physical and chemical reaction to form a corrosion-resistant structure consisting of a narrow layer of zinc and iron alloy. The alloy layer is bonded to the pure zinc layer and the steel strip substrate. As a result, corrosion resistance is very high.
