Process: the hot rolled metal blanks into a 6.5mm thick steel bar that is rod, and then put it Rula Si devices in different diameter pull into line, and gradually narrow the aperture plate drawing, cooling, annealing, coating and other processing of wire made of a variety of different specifications. It contains ingredients are: iron, cobalt, nickel, copper, carbon, zinc, and other elements. Characteristics: more than ordinary soft black iron wire, more flexible, soft and uniform, consistent color. Uses: mainly used in construction, mining, chemical, welding net, welded hangers, and then processing. Soft annealed wire, increase pliability, a construction tie wire, steel banding was more. Currently, annealed wire and wire drawing process commonly used in the production and galvanized. In 1976, galvanized iron wire factory in Guangzhou in China the first application of electrolytic pickling, pressure washing, drying power card successfully tested a new technology drawing a continuous line of production, the intermittent production from the drawing process into a continuous production, reduced the labor intensity, reduce the metal consumption. At that time, China has been able to produce wire rope factory, spoke wire, umbrella wire, spring steel wire, spring steel wire products such as bicycle saddle. 1980s, low carbon steel wire staples with a hot dip, fan guard wire, carbon steel wire, steel bed, also have come out. Packaging: black iron wire galvanized wire packing packaging with the same points in the plastic outer Ma, in the plastic weave, and the first with a thin layer of plastic wrapped around the wire, and then sack or bag and place it around
