Galvanized wire

The galvanized wire is made of high-quality low-carbon steel wire rod. It is made of high-quality low-carbon steel, which has been drawn and formed, pickled and derusted, high-temperature annealed, and hot-dip galvanized. Processed by cooling and other processes. Galvanized wire is divided into hot-dip galvanized wire and cold-dip galvanized wire (electro-galvanized wire).

Introduction of galvanized wire

Production Process

It is made of high-quality low-carbon steel wire rod, which is processed by high-quality low-carbon steel through drawing forming, pickling and derusting, high-temperature annealing, hot-dip galvanizing, and cooling.

characteristic

Galvanized iron wire has good toughness and elasticity, and the highest amount of zinc can reach 300 grams per square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance.

application

Products are widely used in various fields such as construction, handicrafts, weaving wire mesh, highway guardrails, product packaging and daily civilian use.

The iron wire for construction binding is 22# (0.71mm), which is cheap, has good flexibility and is not easy to break. Mainly use low-zinc cold-galvanized iron wire.

Handicraft iron wire is specially processed with one wire, without broken ends, and the amount of zinc is even and bright, and the general price is slightly expensive.

Galvanized wire also includes sprinkling wire: one plate weighs about 100kg-1000kg per roll, and is mainly used in industry, agriculture, and animal husbandry.

Classification of galvanized wire

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

Application range of hot-dip galvanizing:

Due to the thicker coating obtained, 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 structure, power transmission, shipbuilding and other industries. In agricultural fields such as pesticide spray irrigation, greenhouses and construction industries such as water and gas transmission, wire casing, scaffolding, bridges , Highway guardrails, etc., have been widely used.

cold galvanized

Cold galvanizing (electrogalvanizing) is to gradually coat the metal surface with zinc through the unidirectional current in the electroplating tank. The production speed is slow, the coating is uniform, and 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.

The difference between cold galvanizing and hot galvanizing:

The difference between cold-dip galvanizing and hot-dip galvanizing is that the amount of zinc applied is different, and they can be identified from the color. The color of cold-dip galvanizing is bright, silvery white with yellow. Hot-dip galvanized shiny white.
