Hot-dip galvanized wire is more popular in daily life, since the wire is made of metal, it is usually easily corroded in the air. Therefore zinc plating on its surface, can enhance its anti-corrosion ability.
As Galvanized wire manufacturers use high-quality low-carbon steel wire rod, via drawing forming, pickling derusting, high temperature annealing, hot-dip galvanizing, cooling and other processes to produce galvanized wire. Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electro galvanized wire).
Duration of the protective effect of the zinc coating and its thickness has a great relationship. Generally speaking, in the dry environment and indoor use, the required thickness of zinc coating is 6-12μm "only. And in the relatively harsh environment conditions, the thickness of the zinc coating needs to 20μm "hereinafter, may not exceed 50 m."
Accordingly, when selecting the thickness of the zinc coating, you need to consider the environmental impact.
