JSW Neostrands prEN 10138-2009 LRPC Strand

The JSW Neostrands prEN 10138-2009 LRPC Strand, from JSW Neostrands, has been developed for European Union tenders and CE-marked construction programmes that require material tested and reported against the EN 10138-3 property tables.

In line with prEN 10138-2009 requirements, breaking loads range ten diameter/grade rows built around the Y1770S7 and Y1860S7 designations, each with a modulus of elasticity guaranteed at 195 GPa ± 10 and a 1,000-hour relaxation loss ceiling of 2.5% at 70% initial load.

Site engineers turn to the JSW Neostrands prEN 10138-2009 LRPC Strand for continental European bridge and rail projects where design codes reference Eurocode 2 and require prestressing steel data traceable to the EN 10138 series.

Paperwork accompanying the JSW Neostrands prEN 10138-2009 LRPC Strand includes 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.

Coil handling for the JSW Neostrands prEN 10138-2009 LRPC 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.
