Indented and spiral rib PC strand are suitable for pre-stressed concrete engineering which requires strong bonding force and short pre-stress transfer length. It is mainly used in slope protection, geological protection and mine support. They can meet the requirements of PrEN10138, BS5896, ASTMA886, JISG3536, KSD7002, etc. Spiral Rib PC strand is a new product developed by our company. Its side wires are spiral rib wire and center wire is plain round wire with advantage of high tensile strength, good plasticity, stronger anchoring ability and better bond-ability with concrete. It is the first choice for the roadway support and slope consolidating projects.
