Why use Zinc to produce galvanized steel coil?
Zinc is a blue-white metal having a melting point of 419.4 ° C and a density of 7.14 g/cm 3 . Zinc has moderate ductility. Zinc does not change in dry air at room temperature. In the moist air, the zinc surface forms a dense film of zinc carbonate, which protects the interior of the zinc from corrosion.
Since zinc has such an excellent property, zinc is plated on the surface of the steel sheet to prevent corrosion, and this steel sheet is called a galvanized sheet.
