Galvanized steel coil production is a sheet steel which is put into the fusible zinc pot and there is some zinc on its surface.

Galvanized steel coil is produced by passing the full hard sheet which has undergone the acid washing process and rolling process through the zinc pot, thereby applying zinc film to the surface. It has excellent corrosion resistance, paintability, and workability due to zinc’s characteristic.

Continuous zinc coating is the main craft to produce it. It means to put the steel soils into the fusible zinc pot.

Alloy -galvanized steel sheet is also made by hot dipping. But the temperature has risen to 500 degrees when it is out of the zinc pot, then it produces the alloy films.

It has the advantages of adherence and weldability.
