Overview

Pre-tensioning Construction
Pre-tensioning construction procedure: first, stress the prestressed tendons to the designed control stress and fix the bars temporarily on a seat-typed steel mould with tooling anchorage, then pour in concrete. Relax the tendons after the concrete reaches a desirable strength. By this method, the binding force of the bars and the concrete enables the concrete components to obtain prestress. With less process and high efficiency, the pre-tensioning method is easy to operate and ensure the quality. It saves the permanent anchorage for anchoring the prestressing tendons.

Pre-tensioning Anchorage
The pre-tensioning anchorage produced by our company includes line-rod coupler, line-line coupler and rod-rod coupler. These devices connect with material such as Φ25 precision rolled rebar as well as Φ12.7 and Φ15.2 strands, saving a large amount of prestressed tendons for construction companies. These pre-tensioning anchorages are safe, reliable, efficient and material-saving.
