JSW Neostrands AS 1311-1987 Super Grade Strand

Built for Australia project specifications, the JSW Neostrands AS 1311-1987 Super Grade Strand comes from JSW Neostrands and is designed for older Australian project specifications that still reference AS 1311-1987 directly rather than the newer AS/NZS 4672 document.

Fabricated to meet AS 1311-1987, Super Grade, dimensional coverage runs four Super-grade sizes from 9.30 mm to 15.20 mm, minimum breaking loads of 102.0–250.0 kN and a relaxation loss capped at 2.5%, tested on the same computerised UTM and relaxation testing machines used across Neotrex’s range.

Buyers of the JSW Neostrands AS 1311-1987 Super Grade Strand typically specify it across legacy Australian infrastructure contracts, refurbishment work and any tender document that still cites AS 1311-1987 as the governing prestressing steel standard.

Traceability on the JSW Neostrands AS 1311-1987 Super Grade Strand runs back to full batch traceability back to JSW Steel’s integrated wire rod mills, with cryogenic, fatigue and deflected tensile testing carried out at independent global laboratories in addition to Neotrex’s own computerised UTM and relaxation testing equipment on site.

On-site handling of the JSW Neostrands AS 1311-1987 Super Grade Strand follows standard prestressing steel practice: 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.
