Product Description

Serving united states infrastructure demand, D.P. Wires Limited’s D.P. Wires ASTM A416 Grade 270 PC Strand is intended for the North American market’s default choice, Grade 270 being the strand grade most US bridge and building specifications call out today.

Under ASTM A416 tolerances, the available diameters range breaking strengths from 23,000 lb at 3/8 in up to 58,600 lb at 0.6 in (102.30–260.70 kN), min. load at 1% extension figures of 20,700–52,740 lb, and the same 3.5% minimum elongation requirement.

This grade of D.P. Wires ASTM A416 Grade 270 PC Strand is commonly selected for segmental box-girder bridges, parking structure slabs and stadium roof tendons across markets that follow ASTM A416 as their governing prestressing steel specification.

Certification for the D.P. Wires ASTM A416 Grade 270 PC Strand comes through 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 ASTM A416 Grade 270 PC Strand: 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.
