Steel Wire is widely used in the industrial fields and the daily lives. 3mm diameter galvanized steel wire can be as the basic material of many meshes, like weld wire mesh, crimped wire mesh, diamond mesh, hexagonal wire netting, hardwire cloth, slope protect wire mesh, gabion box, filter screen, mine screen mesh, chain link fence, fence netting etc.
Steel Wire also used in other fields like galvanized wire mesh fenceing for the protection of agricultural and commercial properties; used in various automotive components; communication equivaments; packaging products; manufacture of galvanized barbed wire; galvanized wire rope of low and high strength; used in medical components etc.
