Pre-StiRex Corrugated Sheathing ducts, 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.
