The galvanized wire is divided into hot-dip galvanized wire and cold-galvanized wire (electro-galvanized wire).
Hot-dip galvanizing is immersion plating in hot melted zinc bath. The production speed is fast, the coating is thick but uneven, and the market allows a minimum thickness of 45 microns and a maximum of 300 microns or more. The color is darker, consumes more zinc metal, forms an infiltration layer with the base metal, and has good corrosion resistance. The hot-dip galvanizing can be maintained for several decades in an outdoor environment.
Cold galvanizing (electro-galvanizing) is the gradual plating of zinc on the metal surface in the plating tank by the unidirectional current. The production speed is slow, the coating is uniform, the thickness is thin, usually only 3-15 microns, the appearance is bright, and the corrosion resistance is poor. It will rust in a few months.
Relative to hot-dip galvanizing, electro-galvanized production costs are lower.
The difference between cold galvanizing and hot galvanizing:
The difference between cold galvanizing and hot galvanizing is that the amount of zinc on the surface is different, and they can be identified from the color. The color of the cold galvanized is bright and silvery white with yellow. Hot-dip galvanized shines white.
