Corrugated PE Ducts for Pre-Stressing & Post-Tensioning Tendons

Pre-StiRex Corrugated Sheathing ducts are made from high-density polyethylene (HDPE), and serve a distinct purpose in the realm of internal bonded post-tensioning of tendons in pre-stressed concrete. These ducts find application in various projects, including flyovers, bridges, nuclear containments, offshore platforms, via ducts, underpasses, tunnels, and more.

The use of flat ducts becomes particularly popular in construction sectors where the utilization of round section ducts in post-tensioned slabs is impractical due to constraints posed by the slab thickness. These HDPE ducts provide an effective solution, allowing for efficient tendon placement and tensioning within the concrete structures. They contribute to the overall strength and durability of the construction, ensuring optimal performance in challenging environments and critical infrastructure projects.

Post-Tensioning Corrugated PP Ducts

Khelraja review Plus+StiRex ducts and flat ducts, made from polypropylene (PP), offer a distinct advantage in the internal bonded post-tensioning of tendons in pre-stressed concrete. These ducts find application in various projects such as flyovers, bridges, nuclear containments, and offshore platforms, via ducts, underpasses, tunnels, and more.

Flat ducts, in particular, are highly favored in construction sectors where the utilization of round section ducts in post-tensioned slabs is impractical due to the constraints posed by the slab thickness.

The unique properties of Plus+StiRex ducts and flat ducts, including their composition of PP, make them well-suited for these applications. They provide efficient tendon placement and tensioning within the concrete structures, contributing to their overall strength and durability. These ducts play a crucial role in enhancing the performance and longevity of critical infrastructure projects in the field of bonded post-tensioning of tendons.
