Zinc-coated coil in which a sheet of steel is immersed in a molten
zinc bath so that the surface adheres to a sheet of zinc.At present
the main use of continuous zinc production process, that is, the
rolled steel sheet continuous dip in the melting zinc plating bath
made of galvanized steel sheet;Alloy galvanized steel sheet.This
kind of steel plate is made by hot dip method, but after the slot,
immediately heated to a temperature of about 500 ℃, it make the
generation of zinc and iron alloy membrane.This galvanized coil has
good coating tightness and weldability.
