Steel Strand for Prestressed Concrete

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.
Technical Treatment in Production to Ensure Proper Using with Concrete:
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.
