Hot dipped galvanized steel coils are produced through applying cold rolled steel coils pass the melting zinc pot, to get a thin zinc layer at both surfaces. The technique of hot dipped galvanizing assures the zinc adhension to the surface of steel plate. The excellent anti-corrosion performance of galvanized steel coil extends the service life of steel plate. Hot dipped galvanized steel coil are widely used in construction, household appliances, vehicles, container making, and etc…
