D.P. Wires PE Coated Grease-Filled LRPC Strand for Post-Tensioning

D.P. Wires Limited brings the D.P. Wires PE Coated Grease-Filled LRPC Strand for Post-Tensioning to market for unbonded post-tensioning work, where the tendon needs to move freely inside its sheath for the life of the structure.

Governed by ASTM A-416-2006 Grade-1860 / IS-14268:1995 Class II, the mechanical envelope spans a bright or galvanized core strand coated with a corrosion-resistant, high-temperature grease or wax filling the interstices between wires, then co-extruded with a UV-stabilised polyethylene or polypropylene sheath 0.75–1.25 mm thick and a grease loading of 30–35 g per metre.

Demand for the D.P. Wires PE Coated Grease-Filled LRPC Strand for Post-Tensioning is strongest on flat-slab buildings, parking decks and stay cable systems, and the layered barrier of galvanization, grease and polymer sheath also allows individual strands to be monitored or replaced during the structure’s service life.

Manufacturing control on the D.P. Wires PE Coated Grease-Filled LRPC Strand for Post-Tensioning rests on 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.

Storage guidance for the D.P. Wires PE Coated Grease-Filled LRPC Strand for Post-Tensioning: 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.
