Reinforcing Steel PC Strand

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.
