Knitting wire for fittings in coils. Nursultan

Binding wire for fittings in coils Description A long-length metal product made of steel - knitting wire - is used in construction for tying reinforcement and strengthening concrete structures, in industry and mechanical engineering as a raw material for the production of fasteners. Manufacture and characteristics of steel binding wire The raw material for the production of binding wire is steel rod with a low carbon content to give the final product plasticity. The wire rod must have an accurate cross-section and be uniform. Production takes place in two stages: drawing - the workpiece, previously pickled in a sulfuric acid solution, is pulled through a die, where the cross-sectional profile and dimensions of the wire are formed, annealing in bell-type furnaces to relieve stress, remove scale, and subsequent ease of galvanizing. The finished product is repeatedly galvanized or coated with polymeric materials if it is intended to be used in an aggressive environment. Then the knitting wire is cut, straightened, and the ends removed. Cross-section of a knitting wire: round, oval, square, hexagonal, trapezoid. For more information, please call +77029081759
