JSW Neostrands Unbonded Grease-Filled PE Coated PC Strand

Designed and stabilised by JSW Neostrands, the JSW Neostrands Unbonded Grease-Filled PE Coated PC Strand targets unbonded monostrand tendons in flat-slab and transfer-structure construction, where each strand needs to remain free to move within its own sheath.

Verified against Project-specified + PE coating spec, size coverage runs a 12.9 mm bare strand carrying 37–45 g/m of corrosion-inhibiting grease under a saffron-coloured (RAL 2003) PE sheath at least 1.25 mm thick, engineered for even stress distribution and reduced frictional loss along the tendon’s length.

Order volumes for the JSW Neostrands Unbonded Grease-Filled PE Coated PC Strand skew toward residential and commercial flat-slab floors, parking structures and other buildings using unbonded post-tensioning as the primary floor system.

Release of the JSW Neostrands Unbonded Grease-Filled PE Coated PC Strand for dispatch depends on 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.

Like all prestressing strand, the JSW Neostrands Unbonded Grease-Filled PE Coated 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.
