PC steel strand is the simplified term describing Prestressed Concrete Steel Strand Wire. With the advantages of high tensile strength and good corrosion resistance at elevated temperature, PC strand wire is used in heavy loading concrete constructions. It is made with galvanized steel wire or carbon steel wire through drawing, twisting or stranding and stabilizing. The stranded wire structures allow high tension and less distortion in uses.
Prestressed or post tensioned concrete is a method for overcoming concrete's natural weakness in tension. It can be used to produce beams, floors or bridges with a longer span than is practical with ordinary reinforced concrete.
Steel strand for prestressed concrete is where the steel wire or strand is tensioned before the concrete is poured. Once the concrete has cured, the wire or strand are released putting the concrete into compression. Prestressing wire and strand are used in the manufacture of precast concrete T beams for beam and block concrete floors, precast concrete hollow core, solid slabs, railway sleepers and prefabricated buildings.
Post tensioning is where the strand is tensioned after the concrete has been poured. After the concrete has set, the strand is then tensioned and secured. Post tensioning strand is used in floor slabs for multi storey buildings, nuclear containment vessels, water tanks, natural gas tanks and many other concrete structures.
While our company produces various kinds of anti-corrosive steel strand products such as the unbounded steel strand, galvanized steel stand and so on. Now our company is a strong production enterprise, which owns the most various steel strand products with overall structures, specifications and the strongest tension.
Features: High tensile strength, low relaxation, stable modulus of elasticity, stress-relieved, firm connection with concrete, low stress, stable construction, good combination with steel reinforced concrete; saving material, reducing distortion and construction weight, increasing the abrasion resistance, water resistance, stiffness.
Prestressed steel concrete strand or PC strand can also be supplied in various forms for pre- or post-tensioning applications, with plain or galvanized material ranging from 3 wires, 7 wires, 19 wire and compacted construction.
Our PC strand is mainly used for the reinforcement of prestressed concrete structures, such as large-span railway and road bridges, major bridges, silos, buildings, dams, floor slabs, foundations, large concrete vessels, atomic reactor buildings, stadiums, airport hangers, pre-cast segments, crane beams, anchorages and multi-storey industrial buildings etc.
Our steel strand for prestressed concrete is also used for the construction of highways, poles and water towers in civil construction, and energy source sea transportation, house buildings, water control projects, and rock and earth anchoring components to increase the tensile force.
Prestressed concrete used steel strand the international advanced level, especially in the field of reinforcement of rock stratum in the mine. This product characterizes high intensity, high breakage force, high extension, low payment of supporting. The product has a good effect on improving safety coefficient and enhancing anchored force in the field of rock stratum strengthening.
