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.
