Black iron wire has good elasticity and flexibility, which can be controlled during annealing process to adjust its hardness and softness. It is made from high-quality iron wire and is mainly used in the construction industry as binding wire and binding line. The wire gauges mainly include 5#-38# (wire diameter 0.17-4.5mm).

TraitIt is softer and more flexible than ordinary black iron wire, with uniform softness and color consistency.

UsageIt is mainly used in construction, mining, chemical industry, wire mesh, clothing hanger, further processing, etc. After annealing, the iron wire becomes softer and more flexible, making it more effective for construction binding wires and binding reinforcement bars.

At present, the production of annealed wire and steel wire generally adopts the drawing process and zinc plating treatment. In 1976, the Guangzhou Zinc Plated Iron Wire Factory successfully tested the new technology of electrolytic pickling, high-pressure washing, and carding drying for the continuous production of drawing lines, which transformed the drawing process from discontinuous production to continuous production, reducing labor intensity and lowering metal consumption. At that time, domestic wire factories were able to produce products such as steel wires for wire ropes, spokes, umbrella frames, spring wires, and spring wires for bicycle saddles. In the 1980s, hot-dipped low-carbon steel wires for bookbinding, wire for fan grilles, carbon structural wires, and bed wires also appeared successively.

Packing: The packaging of black iron wire is the same as that of galvanized wire, which is divided into inner plastic and outer jute, inner plastic and outer woven, and first uses a thin layer of plastic to wrap the wire, and then uses jute bags or woven bags to wrap it!
