Galvanized Wire - linkland metal wire

Production process: It is made of high-quality low-carbon steel, which is processed by drawing forming, pickling and rust removal, high temperature annealing, hot-dip galvanizing and cooling.

Galvanized wire characteristics: Galvanized iron wire has good toughness and elasticity, and the maximum zinc load can reach 300 g/m2. It has the characteristics of thick galvanized layer and strong corrosion resistance.

Galvanized wire application: Products are widely used in various fields such as construction, handicrafts, woven wire mesh, highway guardrail, product packaging and daily civil use.

Galvanized wire is divided into hot-dip galvanized wire and cold-dip galvanized wire (electro-galvanized wire), the difference is:

Hot-dip galvanizing is immersion plating in the molten 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 can reach more than 300 microns. The color is darker, consumes a lot of zinc metal, forms an infiltration layer with the base metal, and has good corrosion resistance. Hot-dip galvanizing can last for decades in outdoor environments.

Cold galvanizing (electro-galvanizing) is to make zinc gradually coat the metal surface through the unidirectional current in the electroplating tank, the production speed is slow, the coating is uniform, the thickness is thin, usually only 3-15 microns, the appearance is bright, and the corrosion resistance is poor. It usually rusts in a few months.

Compared with hot-dip galvanizing, the production cost of electro-galvanizing is lower.

Application range of hot-dip galvanizing:

Since the resulting coating is thicker, hot-dip galvanizing has better protective properties than electro-galvanizing, 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, petroleum processing, marine exploration, metal structures, power transmission, shipbuilding and other industries. In agricultural fields such as pesticide irrigation, greenhouses and construction industries such as water and gas transmission, wire casing, scaffolding, and bridges , Highway guardrails, etc., in recent years have been widely used.
