Multi-wire Stranding structures Enables PC Strand Ideal Elements for Large Span Concrete Constructions
PC strands are popular in concrete building as low relaxation and high strength combined steel wire units for concrete reinforcing. The multi-wire structure enables a great strength in concrete pre-stressing. The strand length of 1800mm to 3600mm enables longer span structure construction, makes thinner and lighter elements with a reduction in number of piles. Using pc strands also saves consumption of energy in freight and handling. Especially for large-span concrete constructions in bridges, railway, highway, coal mine, stadiums and multi-storey buildings.

Common strand section profiles include 1x2, 1x3, 1x7 wire structures. Popular strands we offer are 1x7 wire structure unbounded pc steel strands: Diameter 12.7mm 7 wire strands, 15.20mm 7 wire, 15.24mm 7 wire and 15.70mm 7 wire. Weight ranges from 2MT to 4MT. Steel rod materials for processing of PC strands are high carbon steel 77B and 82B. Tensile strength can be 1670Mpa, 1770Mpa, 1860Mpa optional.

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.
