High Tensile PC Wire Prestressed Concrete Steel Wire

Cold-drawn steel wire for making reinforcement bars in tension areas of prestressed concrete members. Generally, concrete has high strength to compressive force, but it shows brittleness when it is subjected to tensile force, and it is easy to crack. Prestressed concrete is to make the steel bar in the tension area of the member bear a tensile force in advance and produce a pre-tensile stress. The pretension stress on the steel bar can offset or reduce the tensile stress of the external load on the concrete, thus greatly improving the ability of the tension area to resist the tension, thus reducing the size of the component, saving materials and reducing the weight of the component. Due to these advantages, prestressed concrete components have been successfully applied in many projects such as large Bridges, roof frames, crane beams, industrial and civil prefabricated floors, iron rail ties, electric pole piles, large diameter prefabricated pipelines and atomic power stations. The production of prestressed steel wire has been developed rapidly with the wide application of prestressed concrete members.
