  • Continuous hot dip galvanized steel sheet, referred to as galvanized sheet or white sheet, is a cold-rolled continuous hot dip galvanized steel sheet and steel strip with thickness of 0.25~2.5mm. The steel strip is first burned off the residual oil on the surface through the preheating furnace heated by flame, and at the same time, the iron oxide film is generated on the surface, and then heated to 710~920\u2103 in the reduction annealing furnace containing H2 and N2 mixture gas. The iron oxide film was reduced to sponge iron, and the activated and purified strip was cooled to a temperature slightly higher than that of molten zinc, then the strip was put into a zinc pot at 450~460\u2103, and the surface thickness of the zinc layer was controlled by an air knife. Finally, chromate solution passivation treatment to improve the resistance to white rust.<\/li><\/ul>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    The surface of hot dip galvanized sheet steel is beautiful, with block or leaf shaped crystal pattern, and the coating is firm, with excellent atmospheric corrosion resistance, at the same time, the hot dip galvanized sheet steel has good welding performance and cold processing molding performance. Compared with the surface of hot dip galvanized sheet steel, its coating is thicker, mainly used for the requirement of strong corrosion resistance of the pulling parts.
