The difference between hot galvanized and cold galvanized wire mesh

Galvanized iron wire has good toughness and elasticity, and the maximum zinc loading can reach 300 g/m2. It has the characteristics of thick galvanized layer and strong corrosion resistance. Hot-dip galvanizing. Cooling and other technological processes are processed.

Products are widely used in construction, handicrafts, woven wire mesh, highway fences, product packaging and daily civil use. Galvanized iron wire is divided into hot-dip galvanized wire and cold-dip galvanized wire (electro-galvanized wire).

Hot-dip galvanizing is immersion plating in a molten zinc solution that is heated and ablated. The production speed is fast, and the coating is thick but uneven. The market-approved thickness is 45 microns, up to 300 microns or more. The color is darker, and there are many zinc metals consumed. It forms an infiltration layer with the base metal, and has good corrosion resistance. Hot-dip galvanizing can last for decades in an outdoor environment.

Galvanized iron wire cold galvanizing (electro-galvanizing) is to gradually plate zinc on the metal surface through the unidirectional current in the electroplating tank, the production speed is slow, the coating is average, the thickness is thin, usually only 3-15 microns, bright appearance, corrosion resistance Poor sex, it will rust in a few months.

Galvanized wire is an indispensable product in the current construction industry, handicrafts, woven wire mesh, highway guardrail, product packaging and daily civil use. It is mainly made of low-carbon steel, and its production process is also very special, after drawing forming, pickling and rust removal, high temperature annealing, hot-dip galvanizing. Cooling is the production process it must use. Because of the special production process of galvanized wire, it has good corrosion resistance. Hot-dip galvanizing can be maintained for decades in outdoor environment. In addition, its toughness is also extremely high.
