Plus+StiRex

Plus+StiRex ducts and flat ducts, manufactured from HDPE, have a unique application in the field of internal bonded post tensioning of tendons in pre-stressed concrete viz. projects such as flyovers and bridges, nuclear containments, offshore platforms, via ducts, underpasses, tunnels etc. Flat ducts are especially popular in the construction sectors where use of round section ducts in post tensioned slabs is not possible due to the slab thickness constraints.

Flat Duct 

The unique shape has made it an instant success. It has catered to applications where space is a constraint. Generally speaking, it won’t be possible to use the round section ducts in post tensioned slabs due to the slab thickness constraint. Flat Ducts has proven to be a boon in this sector. The design is quite unique and optimized, which has an edge over the conventional metal ducts.
