The difference between hot dip galvanized wire and cold galvanized wire

Every galvanized wire production into the peak season of the industry, the road to the factory will from time to time to see the transport wire and container container vehicles, as well as galvanized bright wire short-haul transport trucks, led to the surrounding rural labor utilization rate, to solve the employment problem of most people. Galvanized wire is divided into hot galvanized wire and cold galvanized wire, hot galvanized is in the heat of molten zinc dip plating, production speed, thick but uneven coating.

Hot dip wire is dark in color, consumes more zinc metal, and forms infiltration layer with the base metal, and has good corrosion resistance. Hot dip galvanizing can be maintained for decades in outdoor environment. Cold galvanizing is in the electroplating tank through the current unidirectional zinc gradually plated 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. Compared with electrogalvanizing, hot galvanizing has lower production cost and less impact on the environment than electroplating.

Application range of hot dip galvanizing: because of the thicker coating, hot dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for iron and steel parts in harsh working environment. Hot dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, power transmission, shipbuilding and other industries. In recent years, they have been widely used in agricultural fields such as pesticide irrigation, greenhouse and construction industry such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail and other aspects.
