D.P. Wires IS 14268:2017 Class II Low Relaxation LRPC Strand

D.P. Wires Limited engineers the D.P. Wires IS 14268:2017 Class II Low Relaxation LRPC Strand specifically for projects that specifically call for the Class II relaxation limit, a tighter figure checked over a shorter 100-hour test window rather than the 1,000-hour benchmark used for Class I.

Supplied as per IS 14268:2017, Class II, the product line spans a maximum relaxation loss of 1.8% at 70% of specified breaking strength after 100 hours, paired with breaking loads of 102.3–260.7 kN across the 9.5–15.2 mm range and a nominal weight band of 432–1,102 kg/km.

Project teams reach for the D.P. Wires IS 14268:2017 Class II Low Relaxation LRPC Strand on dams, silos, atomic reactor buildings, stadium roofs and airport hangar structures, the heavy civil-works segment where D.P. Wires’ Ratlam facility has built its longest track record.

Documentation on the D.P. Wires IS 14268:2017 Class II Low Relaxation LRPC Strand includes its own in-house physical, mechanical and metallurgical testing laboratory, run under an IS/ISO 9001:2015 quality system that traces back to D.P. Wires’ original ISO 9001:2008 certification by the Joint Accreditation System of Australia and New Zealand (JAS-ANZ) in December 2003. Finished coils are strapped at six points, wrapped in VPI paper, LD-polythene film and one-side laminated bituminised jute before leaving the Ratlam plant.

Before stressing, the D.P. Wires IS 14268:2017 Class II Low Relaxation LRPC Strand should be handled with care: 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.
