D.P. Wires IS 6006:2014 Class 1 Normal Relaxation PC Strand

D.P. Wires Limited produces the D.P. Wires IS 6006:2014 Class 1 Normal Relaxation PC Strand for budget-sensitive prestressed concrete work in the Indian market where a normal relaxation strand meets the design brief.

Produced in conformance with IS 6006:2014, Class 1, the range covers four diameters from 9.5 mm 3-ply up to 15.2 mm 7-ply, with a minimum elongation of 3.5% on a 200–600 mm gauge length and a lay length of 12–16 times the strand diameter, per Class 1 tolerances of IS 6006:2014.

Contractors specify the D.P. Wires IS 6006:2014 Class 1 Normal Relaxation PC Strand for secondary beams, smaller precast girders and general reinforced-concrete work across India where cost takes priority over the tighter relaxation performance of a low-relaxation strand.

Every coil of the D.P. Wires IS 6006:2014 Class 1 Normal Relaxation PC Strand passes through reference clients that include the National Highways Authority of India, several state Public Works Divisions, Nuclear Power Corporation, and the Delhi, Kolkata, Bhopal, Indore, Gujarat and Maharashtra metro rail corporations. D.P. Wires backs each dispatch with its own concurrent quality-control testing rather than relying solely on third-party sign-off.

On-site handling of the D.P. Wires IS 6006:2014 Class 1 Normal Relaxation PC Strand follows standard prestressing steel practice: cut only with an abrasive disc cutter or shear cutter, never with a flame or welding torch, since heat changes the steel’s microstructure and its mechanical properties. Coils should be unloaded with a crane rather than dropped off the vehicle, stored under cover on a raised platform away from direct ground or water contact, and protected with a vapour phase inhibitor if they will sit on site for an extended period before stressing.
