Hot-dip galvanized coil (GI) is produced by passing a pickled and rolled all-hard plate through a zinc pot and coating it with a zinc film on the surface. Due to the properties of zinc, it has excellent corrosion resistance, paintability and processability. Generally, the processes and specifications of hot-dip galvanized steel sheets and galvanized steel coils are basically the same.
Hot dipped galvanized steel coil. A thin steel coil is immersed in a bath of molten zinc so that a layer of zinc adheres to its surface. At present, the continuous galvanizing process is mainly used for production, that is, the rolled steel plates are continuously immersed in a plating bath containing molten zinc to make galvanized steel coils.
Alloyed galvanized steel coil. This kind of steel coil is also made by the hot dip method, but it is heated to about 500°C immediately after coming out of the tank to form an alloy film of zinc and iron. This kind of galvanized coil has good paint adhesion and weldability.
