Newton Exports Unbonded HDPE-Sheathed PT Monostrand

Newton Exports engineers the Newton Exports Unbonded HDPE-Sheathed PT Monostrand specifically for two-way post-tensioned building slabs, parking structures and ground anchor systems that need a fully self-contained tendon rather than a bare strand pulled through a site-installed duct.

Supplied as per ASTM A416 / IS 14268 (core) + HDPE coating, the product line spans a bare 7-wire core strand encapsulated in rust-inhibiting microcrystalline petroleum wax and extruded with a seamless high-density polyethylene sheath, supplied as a complete monostrand system ready to place and stress.

Project teams reach for the Newton Exports Unbonded HDPE-Sheathed PT Monostrand on commercial building slabs and parking decks across the export corridors this guide covers, where speed of installation and long-term corrosion protection outweigh the marginal cost premium over bare bonded strand.

Documentation on the Newton Exports Unbonded HDPE-Sheathed PT Monostrand includes an EN 10204 3.1 mill test certificate recording heat number, full chemical composition, actual breaking force, 0.2% proof load and 1,000-hour relaxation data, packed in 2.5–3.5 MT coils wrapped in multi-layer VCI film and loaded into ISPM-15 certified, silica-gel-dried 20 ft FCL containers.

Before stressing, the Newton Exports Unbonded HDPE-Sheathed PT Monostrand should be handled with care: 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.
