Hot dip galvanizing refers to the process of applying a protective zinc coating to steel or iron sheets to prevent rust. As the all-hard steel is pickled and then coated with a zinc film on the surface of the steel plate through the zinc pot rolling process. Thereafter, hot dip galvanized steel coils (GI) were produced. Hot-dip galvanized steel coil is a popular steel with high corrosion resistance, paintability and processability. It is often widely used in various industries and departments. Aoqi is determined to supply cost-effective galvanized steel coils in China.
