Hot plating is the melting of zinc, and then the other metals (such as iron) through zinc, forming the surface of the zinc coating, electroplating is to put the metal into the electrolyte containing zinc, and the electroplating is carried out.

An electrodeposited layer of zinc deposited on the surface. On the outside, the plating is smooth and the zinc plating is less.

The difference of process: cold and hot galvanizing are relative to these two process methods. Hot galvanizing is the dip plating in the molten zinc liquid, which can be completed in an instant.

Cold galvanizing is to make the zinc plating on the metal surface by using current unidirectional in the plating bath. Hot plating process faster, coating thickness, consumption of zinc metal. Ordinary galvanizing speed is slow, plating

Thin layer.

The galvanized steel wire is bright, the coating is smooth, the hot galvanizing line, the coating thickness, the zinc coating is not smooth.
