Galvanized Iron wire
Galvanized wire is made of high quality low carbon steel wire rod processing, is made of high quality low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, hot dip galvanized, cooling and other technological processes processing.Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire).
Galvanized iron wire, also known as galvanized steel wire, finds most uses in binding of construction materials or weaving of galvanized wire mesh products.
According to the difference of zinc coating process can be divided into: electro galvanized steel wire and hot-dipped galvanized steel wire.
- Galvanized Wire in Small Coils:
Wire diameter: 0.5-1.8mm
Packed in 1kg-20kg small coils. Plastic film inside, gunny bags or woven bags outside.
- Galvanized Wire in Big Coils:
Wire diameter: 0.6-1.6mm.
Tensile strength: 300--500MPa.
Elongation: =15%.
Packing: Big coils of 150kg-800kg.
- Galvanized Wire on Spools:
Wire diameter: 0.265-1.60mm.
Tensile strength: 300--450MPa.
Elongation: =15%.
Packing: On spools of 1kg-100kg.
Characteristice:
galvanized iron wire has good toughness and elasticity, with a thick galvanized layer, strong corrosion resistance and other characteristics.
Galvanized wire is divided into hot-dipped galvanized wire and cold galvanized wire (electrical galvanized wire)
Hot galvanizing is melting in the heat inside the liquid zinc immersion plating, production speed, coating thickness, but are not uniform, the market allows the minimum thickness of 45 microns, up to 300 microns.Color is darker, more consumption of zinc metal, metal forming infiltration layer and matrix, and good corrosion resistance, hot dip galvanized outdoor environment can stay for decades.Because the coating obtained is thicker, hot dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for 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 agricultural fields such as pesticide irrigation, greenhouse and construction such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail, etc., in recent years have been widely used
Cold galvanizing (electric galvanizing) is in the electroplating trough through the unidirectional current zinc gradually plated on the metal appearance, production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, the appearance of light, poor corrosion resistance, generally a few months will rust.Compared with hot dip galvanizing, the production cost of electric galvanizing is lower.
