Details
Prestressing Anchorage System
Product Overview
Prestressing anchorage is a critical load-transfer component in prestressed concrete and post-tensioning systems. It is designed to securely anchor prestressing steel—such as PT Bars or steel strands—and transfer tensile forces efficiently into the concrete structure.
The anchorage system ensures stable force locking after tensioning, minimal slip, and long-term structural safety. It is widely used in bridges, buildings, geotechnical anchoring, tunnels, and heavy infrastructure projects.
| Key Applications: •Bridge construction and rehabilitation •High-rise building structures •Geotechnical slope stabilization •Tunnel and underground construction •Industrial plant foundations | Product Range Single-hole anchorages Multi-hole anchorages (2-31 holes) Wedge-type anchorages Threaded anchorages for PT bars Custom-designed solutions |
