D.P. Wires 3mm 3-Ply Normal Relaxation PC Strand (IS 6006)

D.P. Wires 3mm 3-Ply Normal Relaxation PC Strand (IS 6006) is manufactured by D.P. Wires Limited general reinforcement work that calls for a light, 3-wire construction rather than the heavier 7-wire strand used in main structural tendons.

Manufactured to IS 6006/83, this strand delivers 21.2 mm² of nominal steel area, a minimum breaking strength of 38,250 N (3,902 kg), a 0.2% proof strength of 32,460 N (3,311 kg), and a nominal weight of about 166 kg/km, with a lay length of 24–36 times the wire diameter.

Typical applications for the D.P. Wires 3mm 3-Ply Normal Relaxation PC Strand (IS 6006) include smaller precast elements and secondary reinforcement duties where a full 7-wire strand would be oversized for the load path, while still delivering the fatigue and corrosion behaviour expected of a cold-drawn high-carbon strand.

Behind the D.P. Wires 3mm 3-Ply Normal Relaxation PC Strand (IS 6006) sits 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.

Handling notes for the D.P. Wires 3mm 3-Ply Normal Relaxation PC Strand (IS 6006): 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.
