3X3 PC

3 mm X 3 Ply (3X3) PC Strands are used in prestressing of concrete railway sleepers. They are manufactured in confirmation with IS 6006 - 1983. "Sleeper" is an essential and vital component of railway track. Every year, railways need about 8 to 10 million new sleepers. PC strands are manufactured from high quality of steel of tailor made chemistry, drawn to achieve a tensile strength of 1800 N/mm2. Wires are stranded to achieve perfect length and mechanical properties - tensile strength, proof stress, elongation and relaxation.

  • In built quality checks in all stages of production ie steel making , rolling and wire drawing.
  • Consistency in properties.
  • Narrow tolerances.
