Cold galvanized and hot galvanized difference

Galvanized wire is made of high quality low carbon steel wire rod processing, is made of low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, hot dip galvanized. Cooling process and other processing. Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire).

Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire) :
Hot dip galvanized
Hot dip galvanizing is in hot melt zinc liquid dip plating, production speed, thick but uneven coating, the market allows the lowest thickness of 45 microns, up to 300 microns above. It is dark in color, consumes more zinc metal, forms infiltration layer with base metal, and has good corrosion resistance. Hot dip galvanizing can be maintained for decades in outdoor environment.
Hot dip galvanizing application range:
Because the resulting coating is thicker, hot dip galvanizing has better protective properties than electric galvanizing, so it is an important protective coating for iron and steel products used in harsh working conditions. Hot dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, power transmission, shipbuilding and other industries, in the agricultural field such as pesticide irrigation, greenhouse and construction such as water and gas transmission, wire casing, scaffolding, Bridges, road guardrail and other aspects, has been widely used.

Cold galvanizing
Cold galvanizing (electric galvanizing) is in the electroplating tank through the current unidirectional zinc plating on the metal surface, the production speed is slow, the coating is uniform, the thickness is thin, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust.
Relative hot dip galvanizing, electric galvanizing production cost is lower.
Cold galvanized and hot galvanized difference:
The difference between cold galvanized and hot galvanized is the amount of zinc is different, you can identify them from the color, cold galvanized color shiny silver with yellow. Hot dip galvanized shiny white.
