Plus+StiRex Post-Tensioning Corrugated PP Ducts are polypropylene (PP) ducts designed for internal bonded post-tensioning of tendons in pre-stressed concrete structures. They are used to contain and protect post-tensioning tendons during installation and grouting, helping create durable, high-performance structural systems for civil and industrial projects. Made from PP, these corrugated ducts provide a practical solution where reliable tendon housing, alignment, and grout compatibility are required.
