Galvanized wire is made of high-quality low-carbon steel wire rod through drawing, pickling and rust removal, high-temperature annealing, hot-dip galvanizing, cooling and other process processes.
Features: Galvanized wire has excellent toughness and elasticity, and the maximum zinc coating can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance.
Application: The product is widely used in various fields such as construction, handicrafts, woven wire mesh, highway guardrails, product packaging and daily civilian use.
Galvanized wire is divided into hot-dip galvanized wire and electro-galvanized wire. The main difference is that hot-dip galvanizing is immersion in heated and melted zinc liquid, with fast production speed, thick but uneven coating, and the minimum thickness is 45 microns, and the maximum can reach more than 300 microns. The color is darker, consumes more zinc metal, forms an infiltration layer with the base metal, has good corrosion resistance, and hot-dip galvanizing can last for decades in outdoor environments.
Electro galvanizing is the process of gradually coating the metal surface with zinc through unidirectional current in the electroplating tank. It has a slow production speed, uniform coating, and thin thickness, usually only 3-15 microns. It has a bright appearance and poor corrosion resistance. It usually rusts after a few months. Compared with hot-dip galvanizing, the production cost of electrogalvanizing is lower. Identify them by color. Cold-dip galvanizing is shiny and silvery white with yellow. Hot-dip galvanizing is shiny and white.
Application scope of hot-dip galvanizing:
Because the resulting coating is thicker, hot-dip galvanizing has better protective function than electrogalvanizing, so it is an important protective coating for steel parts used in harsh working environments. Hot-dip galvanized products are widely used in chemical equipment, oil processing, marine exploration, metal structures, power transmission, shipbuilding and other industries. In recent years, they have been widely used in agricultural fields such as pesticide spraying, greenhouses, and construction industries such as water and gas transportation, wire casings, scaffolding, bridges, highway guardrails, etc.
