At present, wire drawing process and galvanizing treatment are widely used in the production of iron wire and steel wire. During the period of 1976, Guangzhou Galvanized Iron Wire Factory successfully applied the domestic new technologies of electrolytic pickling, high-pressure washing and card drying to continuously produce wire drawing, and changed the wire drawing process from intermittent production to continuous production, thus reducing labor intensity and metal consumption. At that time, the domestic iron wire factory could produce steel wire rope, radial low steel wire, umbrella steel wire, spring steel wire, bicycle saddle spring steel wire and other products. In the 1980s, we also produced hot-dip low-carbon steel wire, fan screen steel wire, carbon structural steel wire and bed steel wire. After annealing, the ductility of iron wire is increased, which makes the product softer and increases the application range of iron wire. It has been widely used in screen production, such as galvanizing, hot dip galvanizing and copper electroplating. The method of weaving first, electroplating first, and weaving later is adopted for the binding of building steel bars. The treated wire mesh or steel wire mesh has good corrosion resistance and oxidation resistance, and can be used for reinforcement and protection in construction, petroleum, chemical industry, aquaculture, garden protection, food processing and other industries.
For example, the welded wire mesh widely used in industry, agriculture, aquaculture, construction, transportation, mining and other fields is made of high-quality low-carbon iron wire, and then the surface is passivated and plasticized by cold plating (electroplating), hot plating and PVC plastic coating. The produced metal mesh is flat, uniform in mesh and firm in solder joints, and has the characteristics of stability, corrosion resistance and good corrosion resistance. Stainless steel welding net is made of high quality stainless steel wire; For example, machine protective covers, animal and livestock fences, flower fences, window fences, passage fences, poultry cages, vegetable baskets and paper baskets in home offices, and decorative items are more acid and alkali resistant, welded firmly and beautiful.
