Product Description

D.P. Wires Limited rolls out the D.P. Wires ASTM A416 Grade 250 PC Strand to serve US-specification projects and American contractors sourcing prestressing steel by imperial diameter rather than metric.

Tested and approved to ASTM A416, the strand family covers Grade 250 minimum breaking strengths of 20,000–54,000 lb (89.0–240.2 kN) across the standard imperial range of 3/8 in to 0.6 in, checked to a 3.5% minimum elongation on a 600 mm gauge length.

Structural engineers deploy the D.P. Wires ASTM A416 Grade 250 PC Strand in legacy designs and retrofit work that were originally detailed against Grade 250 material, where matching the original specification matters as much as matching the diameter.

Packaging for the D.P. Wires ASTM A416 Grade 250 PC Strand follows 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.

Like all prestressing strand, the D.P. Wires ASTM A416 Grade 250 PC Strand needs careful site handling: 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.
