Excellent corrosion resistance
The steel sheet is covered with a uniform zinc-plated layer by controlling the amount of zinc coating. Thezinc-plated layer itself is chemically treated, which ensures excellent corrosion resistance.
The raw materials in coil forms are continuously annealed, galvanized,and properly leveled, granting final products superior formability.
With galvanization, a piece of industrial steel is expected to last more than 50 years in averageenvironments, and can last over 20 years with severe water exposure.
Hot-dip galvanized steel sheet
Hot-dip galvanized steel sheets are heat-affected during the subsequent galvanizing stage;so they lose someof their normal workability compared to the normal hotrolled and coldrolled steelsheets.The surface layer is pure zinc, with excellent ductility. Between the base metal and the surfacelayer are thin alloyed-layers of iron and zinc, but their structure and thickness are strictly regulated so that the zinc-plated layer will not peel off.
