Tata Wiron AS 1311-1987 Super Grade Strand

Designed and stabilised by Tata Wiron (Tata Steel), the Tata Wiron AS 1311-1987 Super Grade Strand targets Australian buyers whose material schedule still references the 1987 edition of AS 1311 rather than the later AS/NZS 4672 revision.

Verified against AS 1311-1987, Super Grade, size coverage runs four Super-grade sizes between 9.30 mm and 15.20 mm with minimum breaking loads of 102.0–250.0 kN, each produced on the same fully integrated manufacturing cycle Tata Steel runs from iron-ore sourcing through to finished wire.

Order volumes for the Tata Wiron AS 1311-1987 Super Grade Strand skew toward legacy Australian structures and refurbishment contracts where the original design documentation still calls out AS 1311-1987 by name.

Release of the Tata Wiron AS 1311-1987 Super Grade Strand for dispatch depends on Tata Steel’s fully integrated manufacturing cycle, from its own iron ore mines through in-house steel making and wire rod rolling at Tarapur, Indore and Jamshedpur, supplied in reeless cheese coils of 1–3.5 MT in either dry or oiled condition depending on site storage conditions.

Site precautions for the Tata Wiron AS 1311-1987 Super Grade 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.
