Soft Steel
About our Products Products Soft Steel

Steel Bar

This is a product used in the cold drawing of wires. Soft steel has a variety of uses, including its use in ordinary wire, wires for nails, annealing wires, wires for welded wire netting, wire mesh, and wires for crimp wire netting. Wire rods use 5.5~12 mm as their material and are used in car sheets, door locks, construction materials, etc.

  Remarks

  1. The diameter and nominal diameter that are not expressed in the diagram have higher values than those listed.
  2. The products marked with ‘-‘ and that are expressed on the diagram are ones to which mechanical properties are not
      applied. The parts marked with ‘/’ are products that do not exist, and so are exempt from measurements.
