The hot plating wire is made of low carbon steel wire rod and processed by drawing, pickling and rust removal, high temperature annealing, hot dip galvanizing and cooling. Galvanized iron wire has resistance and elasticity, the amount of zinc can reach 300 grams/square meter, and has the characteristics of thick galvanized layer and strong corrosion resistance. Widely used in construction, handicrafts, wire mesh, highway guardrail, commodity packaging and ordinary civilian and other fields.
Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire). Hot dip galvanizing is dipped in the heated melting zinc liquid, the production speed is fast, the coating is thick but not uniform, the market thickness is 45g, up to 300g or more. The color is dark, the consumption of zinc metal is much, the entry layer is formed with the base metal, the corrosion resistance is good, and the hot dip galvanizing can persist for decades in the outdoor environment.
Cold galvanizing (galvanizing) is in the plating tank through the current unidirectional, so that the zinc is gradually plated on the metal surface, the production speed is slow, the coating is uniform, the thickness is thin, usually as long as 3-15g, the appearance of bright, poor corrosion resistance, usually a few months will rust. Compared with hot dip galvanizing, the production cost of electric galvanizing is lower.
Because the resulting coating is thicker, hot-dip galvanizing has a very good protective function than electric galvanizing, so it is an important maintenance coating for steel parts used in strict working environments. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, electricity transportation, shipbuilding and other occupations, in the agricultural field such as pesticide irrigation, heating and construction industries such as water and gas transport, wire bushings, scaffolding, Bridges, highway guardrail, etc., these years have been a large number of selected.
Compared with electric galvanized iron wire, the zinc layer is higher, the anti-corrosion performance is better, and it is suitable for the more important anti-corrosion and anti-rust status.
