PRODUCT DESCRIPTION

Cold Rolled Pre Galvanized Welded Square / Rectangular Steel Pipe Hot dip galvanizing and zinc iron alloy have superior properties, including good corrosion resistance, forming, and coating. They are mainly used in the construction, household appliances, automotive, and metallurgical industries. The construction industry is mainly used for roofs, doors and windows, rolling shutter doors, suspended ceiling keels, etc; Household appliances are used for refrigerators, washing machines, etc; The automotive industry is mainly used for body casings, chassis, doors, fuel tanks, mudguards, etc; The metallurgical industry is mainly used for steel window blanks, color coated plate substrates, etc. Hot Dipped Galvanized Steel Sheet in Coil (GI coil) is produced by passing the Full Hard sheet which has undergone the acid washing process and rolling process through the zinc pot, thereby applying zinc film to the surface. It has excellent corrosion resistance, paintability, and workability due to Zinc’s characteristic. Usually hot dipped galvanized steel sheet and galvanized steel coil process and specifications are basically the same.
