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 A 416, GB/T5224-2003, BS5896, JISG3536-88 standards.
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 A 416, GB/T5224-2003, BS5896, JISG3536-88 standards. Especially for large-span concrete constructions in bridges, railway, highway, coal mine, stadiums and multi-storey buildings.
The pc strands are made of continued drawing with large deduction stranding then stabilizing treatment;
The carbon steel materials have high rate of yield strength and ultimate strength, Low relaxation;
Steady modulus of elasticity, stress relieved in production, highly fixed with Concrete.
