Spiral Ribbed PC Wire
Helical Rib PC wire appearance of the main characteristics are rolling pull-out process will deal with semi-finished products after the plastic deformation after the last drawing, so that wire formed on the surface of four consecutive convex-shaped rib, whether appearance or material processing method is excellent features to plain steel wire and strand.
Helical ribbed PC strand wire has on the surface 3-6 consecutive convex-shaped ribs. The advantage is that it can strengthen the bond between wire and concrete, thus improves the performance of the PC products and extends its life.
Spiral ribbed PC steel wire:
1. Diameter: 4.00mm-12.00mm.
2. Standard: ASTM, BS, DIN, GB.
3. Strength: 1570Mpa, 1670Mpa, 1770Mpa.
Standard: GB/T5223, ASTMA421, BS5896, JISG3536, ISO6934, EN10138 or other special required standards.
Spiral ribbed PC wire has a wide range of use, such as bridges, subway, railway sleepers, poles, dams, nuclear power plants, high-rise buildings and houses, etc.
