General Introduction: Hot-dipped zinc plated wire is also known as hot dipped galvanized wire or thermal galvanized wire. It is made by mean of wire drawing followed by heat treatment and zinc plating.

Wire Materials: Iron wire, carbon steel wire.

Advantages: Excellent flexibility and softness. The zinc coating can be 100g/m2, 200g/m2 and 300g/m2.  Single coil package for hot-dip galvanized iron wire can be different from 10 kg to 1000 kg. 

Application: As tying wire in agriculture for vines and orchards, as weaving wire in the fencing and netting industry, as material for packaging of products and other daily uses.

Hot Dip Galvanized Wire in Various Packing Forms

Why Choose Galvanized Steel Wire Thermal Zinc Plated? Or, the major Differences between Thermal galvanized and electro galvanized wire?

Galvanized wire hot-dip zinc-plated is also known as thermal zinc plated gal. wire or HDG wire. Electro-galvanized wire is also called electroplating wire or cold galvanized wire. They are all produced from quality wire rods of 1006、1008、1018、Q195. The zinc applied for plating is ZINC WITH 99.995% purity. Hot dip galvanized wire andelectro galvanized steel wire both can be used extensively as weaving wire, tying wire, staple wire and fencing wire. Similar wire diameters applied to them.

The major differences lies in three aspects: the zinc coating processing method, the zinc coating quantity and the wire properties.

Processing Differences:
Electroplating is achieved by placing the zinc ingots, zinc wire in a liquid bath energized at a current. Under the magnetic field, the zinc atoms lose electrons to become ions, free out of the zinc block, gradually adsorbed onto the steel wire object to be plated.

Thermal zinc plating or hot dip plating is made by placing the steel wire immersed in a liquid bath of hot melt zinc. The zinc layer is formed through intense high-temperature chemical reaction process.

Hence, the electroplating is also called cold plating and the later hot dip plating.

Zinc layer thickness and zinc coating quantity difference:
Cold galvanized layer is extremely thin, usually only 3-15 microns;
Hot-dip galvanizing layer is thick, the minimum thickness is 45 microns, maximum up to 300 microns.

Property and Service Life Differences:
Electro cold galvanized wire with a thin zinc covering can only serve a short life. It is bright at the beginning, then become pickling or oxidized under conditions of insufficient acid or humid air within several weeks.
Hot-dip zinc galvanized steel wire enjoys excellent corrosion resistance. Depending on zinc layer thickness, it can be used for several years or decades before heavily oxidized.
