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.
