Galvanized wire is divided into hot-dip galvanized wire and electro-galvanized wire. The difference is:
The hot-dip galvanized wire is dipped in the heated and melted zinc solution. The production speed is fast, and the coating is thick but uneven. The minimum thickness allowed by the market is 45 microns, and the maximum thickness is more than 300 microns. The color is darker and consumes a lot of zinc metal. It forms an entry layer with the base metal, and has good corrosion resistance. Hot-dip galvanizing can last for decades in an outdoor environment.
Electro-galvanized wire is to gradually coat zinc on the metal surface through the unidirectional current in the electroplating tank. The production speed is slow, the coating is uniform, and the thickness is thin, generally only 3-15 microns, the appearance is bright, and the corrosion resistance is poor, generally 1- It will rust in 2 months. (The new electroplating environmental protection technology greatly improves the corrosion resistance of cold galvanizing)
Production technology: It is made of high-quality low-carbon steel wire rods.
Characteristics of galvanized wire: Galvanized iron wire has excellent resistance and elasticity, and the maximum amount of zinc can reach 300 grams per square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance.
Application of galvanized wire: The products are widely used in various fields such as construction, hand technology products, weaving wire mesh, highway guardrails, product packaging and ordinary civil use.
Compared with hot-dip galvanized wire, the price and cost of electro-galvanized wire are relatively low.
Hot dip galvanizing application plan:
Because the resulting coating is thicker, hot-dip galvanizing has a very good protective function than electro-galvanizing, so it is an important protective coating for steel parts used in severe working environments. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, marine exploration, metal structure, power transmission, shipbuilding, etc., in agricultural fields such as pesticide sprinkler irrigation, greenhouse and construction industries such as water and gas transportation, wire casing, scaffolding, bridges , highway guardrails, etc., have been widely used in recent years.
