Black Wire English name: black iron wire 
 Process: the hot metal billet rolled into 6.5mm thick steel that is rod, and then put it Rula Si device into a different diameter wire pull, and gradually narrow the drawing aperture plate, for cooling, annealing, coating processing technology such as a wire made of a variety of different specifications. It contains ingredients are: iron, cobalt, nickel, copper, carbon, zinc, and other elements. Characteristics: Black iron wire is more flexible than ordinary, more flexible, soft, uniform, consistent color. Uses: mainly used in construction, mining, chemical, welding mesh, welding hangers, and then processing. Soft annealed wire, Flexibility increases as a construction tie wire, steel banding effect is more. Currently, annealed wire and wire commonly used in the production process and galvanized wire drawing. In 1976, galvanized iron wire factory in Guangzhou in China the first application of electrolytic pickling, pressure washing, drying power card successfully tested the new technology has a brushed continuous production line, so that intermittent production from the drawing process into a continuous production, reduced the labor intensity, reduce the metal consumption. At that time, China is capable of producing wire rope factory, spoke wire, umbrella wire, spring steel wire, spring steel wire products such as bicycle saddle. 80 years of the 20th century, with a hot dip low carbon steel wire staples, wire fan guards, carbon structural steel, steel bed, also one after another. Packaging: black iron wire galvanized wire packing packaging with the same points in the plastic linen, woven in plastic, and the first with a thin layer of plastic wrapped around the wire, and then sack or bag to wound ! Specifications: wire gauge size SWG (mm) BWG (mm) metric (mm)
