Product details
Hot dip galvanising is the process of applying a protective zinc coating to steel sheet or iron to prevent rusting. As fully hardened steel is pickled and then coated with a zinc film on the surface of the steel sheet through a zinc pot rolling process. Thereafter, hot dip galvanised steel coils (GI) are produced. Hot dip galvanised steel coil is a popular steel with high corrosion resistance, paintability and workability. It is often used in a wide range of industries and sectors.
