Cold-drawn Wire Prestressed Concrete (CWPC)

The cold-drawn low-carbon steel wire used for prestressing is made of ordinary hot-rolled carbon steel coil rod. This is processed at room temperature through a special wire drawing die. The low-carbon coil rods are manufactured by the steel mill; the wires are processed at the prefabrication plant. By cold-drawing the low carbon coil rod into wires, the strength is enhanced about twice as much as that of the coil rod. CWPC technology is suitable for producing small and medium size members, such as beams, slabs, roof trusses, window and door frames. CWPC members can cause savings up to 30-50% steel consumptions and can reduce about 10% the cost of construction.
