Tata Wiron prEN 10138-2009 LRPC Strand

Built for Europe project specifications, the Tata Wiron prEN 10138-2009 LRPC Strand comes from Tata Wiron (Tata Steel) and is designed for Tata Steel’s European wire business, which the company lists as established in Europe alongside India, Thailand, China, Sri Lanka, the USA, Australia and the Middle East.

Fabricated to meet prEN 10138-2009, dimensional coverage runs ten diameter/grade combinations built around the Y1770S7, Y1860S7, Y1860S7G and Y1820S7G designations, with a modulus of elasticity of 195 GPa (±10) and relaxation loss capped at 2.5% at 70% initial load as required under prEN 10138-2009.

Buyers of the Tata Wiron prEN 10138-2009 LRPC Strand typically specify it across the Piombino works in Italy and the wider European steel network Tata Steel operates alongside its Indian wire plants, giving European buyers a strand line with regional manufacturing presence behind it.

Traceability on the Tata Wiron prEN 10138-2009 LRPC Strand runs back to 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.

On-site handling of the Tata Wiron prEN 10138-2009 LRPC 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.
