China DAQIANG PC strand used for steel grating/roofling sheet/steel frame/steel building/bridge/railway sleeper.Ect
GB T5224/JIS 3536/ BS5896 /ASTM A416
High tensile strand for pre-stresses in concrete structure by virtue of improved proportional limit, higher ductility combined with higher strengths. They may be supplied in drawn or drawn straightened or stress relieved conditions. They can also be supplied in plain or indented finish. These are manufactured to different international standards and to the specific requirement of each customer.
