Low relaxation PC strand is one of the most important products in our enterprise,which is used to match the highend structures of concrete such as railways,highways,bridges,mine,nuclear power plant,hydropower,large-span buildings and so on.
Low relaxtation PC strand is made by 7or 19 colddrawn light circle steel wires or indented wire,which is applied to high efficiency and energy saving materials of concrete structures after stabilizing treatment.The stabilizing treatment take advantage of the calefaction temper of tensional medium frequency induction.The technology of producing low relaxation PC strand is independent intellectual property of our enterprise.The low relaxation products own the core competence,which reach the advanced interational standard.
The diameter and structure of the product ranks 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.
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.
