Detailed Engineering Description
In order to protect the surface of steel suspension supports and post-tensioning tendons in concrete structures from corrosion, rust and moisture damage, they must be housed within high-integrity sheathing pipes.
Manufactured from premium corrugated HDPE or galvanized steel strip, these sheathing pipes offer optimal bond characteristics with surrounding concrete while guaranteeing leak-tight grout encapsulation. We offer a full range of internal and external diameters tailored to client project requirements, with ease of installation on bridge girders and post-tensioned slabs.
