P C Strand

P C Strand are widely used in the construction of bridges, car parking garages, nuclear reactors, slabs, silos, hangars, aquaducts, high rise buildings, viaducts & railway sleepers .
It is manufactured as per any other International Specifications and as per customer requirements. They are available in many sizes such as plain, indented & galvanized form.

Properties

High strength
Consistency of physical properties
Consistent coil characteristics with uniform winding
Close tolerances on unit mass to length ratio
Higher breaking loads
Higher proof stress loads
Higher fatigue and corrosion resistance
Better performance at elevated temperature
Lower relaxation losses
