 Model Number PC strand

Low relaxation pre-stressed concrete steel strand (pc strand) Specification: Low relaxation, left (or right) hand lay, high tensile (1860mpa), according to ASTM416-99, or BS5986 Diameter: 9.53mm,12.7mm,15.24mm,17.8mm,23mm (other size against specific inquiry) Packing: approx 3 MT per coil; wrapped by poly-woven clothes, and bundled by steel strips. 7 coils loaded into one 20ftcontainer. Application: pc strand can be widely used as a new steel material taking place of traditional constructional material, such as re-bar, wire rod. PC wire strand is mainly used in the upper plates of bridges, as cable for special bridges and for the maintenance of bridges. In construction, this product is used in concrete pilings and supports for the construction of buildings, domes for nuclear power plants and reinforcement of lng concrete tanks. It is also used in the floor and roof reinforcement of sports stadiums. Besides these general uses, the products are essential in large-scale cargo recovery and offshore platform jobs in which cranes and other recovery equipment cannot be used, in construction maintenance, anchors for civil engineering work, and of course, for rail ties for railroad and high-speed trains. Additionally, these products can be extensively used in construction materials for PC panels, high-pressure concrete water pipes, marine structures, towers and runways.
