We have three types of PC wire including plain surface, spiral ribs pc wire and indented pc wire.PC Wire and PC Strand have a wide range of use, such as bridges, subway, railway sleepers, poles, dams, nuclear power plants, high-rise buildings and houses, etc.
Active standard: GB/T5223, ASTMA421, BS5896, JISG3536, ISO6934, EN10138 or other special required standards
Helical Rib PC strand 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.
The character of the spiral ribs wire is there are 3-6 protruding ribs on the surface, and 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.
