black wire fired wire black wire binding wire factory

black wire has good elasticity and flexibility, and can control its hardness and softness during the annealing process. it is made of high quality iron wire and is mainly used for binding wire and binding wire in the construction industry. the silk number mainly has 5#-38#(silk warp 0.17-4.5mm)

characteristics: softer than ordinary black wire, more flexible, even softness and consistent color.

purpose: mainly used in construction, mining, chemical industry, welding mesh, welding hangers, reprocessing, etc. after annealing, the iron wire becomes soft, the flexibility increases, and the building binding wire is made, and the binding effect of steel bar is more.

at present, the production of annealing wire and steel wire generally adopts wire drawing process and galvanizing treatment. in 1976, guangzhou galvanized iron wire factory first applied the new technology of electrolytic pickling, high-pressure flushing and card electric drying in china. it successfully produced nail drawing thread continuously, making the wire drawing process change from intermittent production to continuous production, it weakens labor intensity and reduces metal consumption. at that time, domestic wire factories had been able to produce wire rope, spoke steel wire, umbrella steel wire, spring steel wire, bicycle saddle spring steel wire and other products. in the 1980 s, hot-plated low-carbon steel wire, fan guard steel wire, carbon structural steel wire, bed surface steel wire and so on were also published one after another.

packaging:the packaging of black wire is the same as the packaging of zinc plated wire. it is divided into plastic lining, linen lining, plastic lining and outer weaving. first, use a thin layer of plastic to wrap the wire around, and then use hemp bag or woven bag to wrap it around!
