How to distinguish galvanized wire and hot-dip galvanized wire

Galvanized binding iron wire is based on iron wire or steel wire, and is made into cold drawn wire after being drawn through the drawing process. The application field and scope of these galvanized wires are determined according to the thickness of the galvanized layer.Then the process classification of galvanized wire is introduced here. The galvanizing process of galvanized wire is mainly divided into two types: one is cold galvanized (also called electro galvanized), the other is hot-dipped galvanized.

The cold galvanized/electrogalvanized process mainly relies on the unidirectionality of the current to allow zinc to be slowly plated on the metal surface. The thickness of the galvanized wire made by this method is even and thin. However, the cost of production is relatively low, and the consumption of zinc metal is relatively less. At the same time, the service life is relatively short with hot-dipped galvanized wire.

Hot dip galvanizing is to dip the cold wire into the hot molten zinc metal solution for plating, forming an infiltration layer in the metal itself.Zinc coating of galvanized wire made by this process is stable and not easy to fall off, with long service life.But as for zinc metal consumption,the production cost is high, the thickness of the coating is not uniform relatively.
