What’s SUPRO STRAND? SUPRO STRAND: Prestressing tendons (stranded steel wires for pre-stressed concrete ) featuring excellent anti-corrosion property with wide applications for civil engineering. SUPRO STRAND is an innovative prestressing tendons (stranded steel wires for pre-stressed concrete) featuring its high durability, realized by fully-adhesive, anti-corrosive resin coating, ideal for prestressed concrete in civil engineering. The most remarkable feature of SUPRO STRAND lies in its fully adhesive and anti-corrosive resin impregnation, achieved without unraveling stranded wires of prestressing tendons. Realized is the excellent anti-corrosiveness, applicability and strength Since coating of conventional cables required unraveling of stranded wires, mechanical strength properties of prestressing tendons (stranded steel wires for pre-stressed concrete) tended to change. However, SUPRO STRAND, which does not involve unraveling of stranded wires in its manufacturing process, will not cause any change in mechanical strength properties of prestressing tendons. This gave rise to cables with excellent anti-corrosiveness, constructability and strength, best suited for prestressed concrete in civil engineering. Unwinding of PC stranded wire. Rewinding of SUPRO Strand Contribute to civil engineering properties, especially in needs of SEISMIC or SALINE measures. Constructability of SUPRO STRAND contributes to shorten labor-intensive wire-installation works, while its high anti-corrosiveness greatly enhances civil engineering properties, especially in needs of seismic or saline measures. SUPRO STRAND also receives a high reputation in the applications in unbonding wires for post-tensioned concreting systems, ropes for landfill bay works, diagonal supporting cables for extradosed bridges and earth retaining cables.

Pre-stressed concrete is a construction method used for most of concrete bridges recently built in Japan. Pre-stressing tendons are used to produce compressive stress, which offsets tensile stress caused over a period, preventing concrete foundation from cracking. Great benefits by excellent technologies and performance Incredible anticorrosive performance Incredible anti-corrosion ensures long-lasting integrity of stranded steel wire strength. First in the world!! For the first time in the world, we’ve succeeded iｎ supplying 19 stranded steel wire specifications. Outstanding constructability Outstanding constructability will ensure flexibilities in construction works. Pinhole-free No pinholes are produced on the surface coating materials thanks to the special anticorrosive property. No slacks in pre-stressing tendons Since pre-stressing tendons are processed with filled resin and coating materials, high performance shall be maintained without slack. Complete adhesiveness Strongly adhered to each wire of pre-stressing tendons, anticorrosive materials will never be removed until stranded wires are broken off. Great water-tightness There is no water penetration under high pressure. Excellent adherability SUPRO STRAND’s high adherability to concrete prevents tendons from slided off when stress is induced.
