The corrosion resistance of hot dip galvanized is much higher than that of cold dip galvanized, also known as electric dip galvanized. Hot wire will not rust for several years, cold galvanized will rust within three months. The cold galvanizing process is used to protect the metal from corrosion, for which the coating of zing filler is used,which is applied to the protected surface by any of the coating methods and dried to form a zinc filler coating with a zinc content (up to 95%) in THE DRY coating.

As we all know, the mechanism of resistance to atmospheric corrosion of zinc includes mechanical protection and electrochemical protection. Under the condition of atmospheric corrosion, there are ZnO, Zn(OH)2 and basic zinc carbonate protective film on the surface of zinc layer, which to a certain extent slows the corrosion of zinc. When this protective film (also known as white rust) is damaged, a new film will be formed.

Galvanized wire is immersed in heated molten zinc, the production speed is fast, the coating is thick but uneven. The thickness of 45 microns allowed by the market, the color is dark, the consumption of zinc metal is more, and the matrix metal is formed into an infiltration layer, and the corrosion resistance is good. The hot dip galvanizing can be maintained for decades in the outdoor environment.
