Spiral Ribbed PC Wire
Spiral ribbed PC steel 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.
Spiral ribbed PC steel 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.
Diameter: 4.00mm-12.00mm.
Standard: ASTM, BS, DIN, GB.
Strength: 1570Mpa, 1670Mpa, 1770Mpa.
Standard: GB/T5223, ASTMA421, BS5896, JISG3536, ISO6934, EN10138 or other special required standards.
Quality
Our Low Relaxation Sprial Ribbed PC Wire is the first in China to pass the hydrogen embrittlement sensitivity test conducted according to American Standard, reaching the highest leval of 200h, and the product is applied to key national projects such as the water diversion project in large houses.
Our PC Wire are purchased by many domestic rail pillow factories, electric pole factories and foreign customers.
Standard: The current standards are GB/T5223-2014 Prestressed concrete steel wire”, according to market requirements, also according to ASTMA421-16, BS5896-2012 and other foreign standards.
Raw Material: SWRH77B and SWRH82B
