Product Description
Steel strands for prestressed concrete are made of the high carbon steel wire rods SWRH82B and have the characteristics of high tensile strength, low relaxation, steady modulus of elasticity, relieved stress, and high adhesion with concrete through continuous drawing with large deduction stranding and stabilization treatment to meet the ASTM A416, BS 5896, and GB/T5224 standards. Such steel strands are primarily used in highways, bridges, key water control projects, anchoring tension members, and lift tension members.
