Galvanized coil: a thin steel sheet that immerses the steel sheet
into the molten zinc bath to make its surface adhere with a layer
of zinc. It is mainly produced by continuous galvanizing process,
that is, the rolled steel plate is continuously immersed in the
zinc melting bath to make galvanized steel plate; Alloyed
galvanized steel sheet. This kind of steel plate is also made by
hot dip method, but it is heated to about 500 ℃ immediately after
coming out of the groove to form an alloy coating of zinc and iron.
The galvanized coil has good coating adhesion and weldability.
