Galvanized iron wire has good toughness and elasticity, the highest amount of zinc can reach 300 g/m2. It has the characteristics of thick galvanized layer and strong corrosion resistance. Galvanized iron wire products are widely used in construction, handicrafts, wire mesh, highway guardrail, product packaging and daily civilian and other fields. Galvanized iron wire is divided into hot galvanized iron wire and cold galvanized iron wire (electric galvanized iron wire).
The difference is:
Hot dip galvanizing is dipped in molten zinc, the production speed is fast, the coating is thick but uneven, the market allows the minimum thickness of 45 microns, up to 300 microns or more. Dark color, zinc consumption metal, and the matrix metal formation of infiltration layer, good corrosion resistance, outdoor environment hot dip galvanizing can be maintained for decades.
Cold galvanizing (electric galvanizing) is in the electroplating tank through the current unidirectional zinc gradually plated on the metal surface, the production speed is slow, the coating is uniform, the thickness is thin, usually only 3-15 micron, the appearance of bright, poor corrosion resistance, generally a few months will rust. Compared with hot dip galvanizing, electric galvanizing has lower production cost. Application and scope because the coating is thicker, hot dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for iron and steel parts in harsh working environment.
Hot dip galvanized products in chemical equipment, petroleum processing, Marine exploration, metal structure, power transmission, shipbuilding and other industries have been widely used in agricultural fields such as pesticide irrigation, greenhouse and construction such as water and gas transmission, wire casing, scaffolding, bridge, highway guardrail, etc., has been widely used in recent years.
Stainless steel material Stainless steel refers to air, steam, water and other weak corrosive medium and acid, alkali, salt and other chemical corrosion medium corrosion of steel, also known as stainless acid steel. In practical application, the steel with weak corrosion resistance medium is often called stainless steel, and the steel with chemical corrosion resistance is called acid-resistant steel.
Due to the difference in chemical composition between the two, the former is not necessarily resistant to chemical medium corrosion, while the latter is generally stainless. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel. Stainless steel wire drawing is a metal working (stainless steel) process, is today’s stainless steel and aluminum products industry one of the most popular surface treatment technology. Is for stainless steel and aluminum products for drawing effect treatment.
