Individual single-hole anchorages offer greater flexibility than multi-hole anchor groups, allowing for distributed placement as required.
The square flange base features integrated mounting holes, enabling direct attachment to the formwork.
Constructed from high-strength cast iron, the base offers high compressive load-bearing capacity, effectively distributing the concentrated tensile force from the tensioned steel strands evenly into the surrounding concrete.

The anchor bearing plate and plastic trumpet guide sleeve come pre-assembled, eliminating the need for on-site assembly of loose parts. This improves efficiency in strand threading and formwork positioning while reducing the risk of missing components. The square flange base features built-in mounting holes for direct attachment to formwork, ensuring easier control over positioning accuracy.
The black tapered trumpet-shaped top smoothly guides the steel strand into the anchor hole and disperses tensioning stress, preventing stress concentration and cracking in the concrete at the anchor end. An internal rib structure prevents the plastic sleeve from deforming under pressure.
Wedge-Type Self-Locking Anchorage
Utilizes matching split alloy steel wedges that grip the strand tightly via the wedging force generated during tensioning and retraction; the system offers strong self-locking capabilities and resists loosening under long-term loads.
Offers high compressive load-bearing capacity, evenly distributing the concentrated tensile force from the strand to the surrounding concrete. It provides superior impact and deformation resistance compared to standard cast steel components, making it suitable for high-tonnage tensioning applications.
Provides electrical insulation and corrosion protection by isolating the strand from direct contact with concrete; suitable for unbonded prestressing systems and designed to reduce friction and wear during strand threading.
Quenched and Hardened Wedges
Internal teeth grip the surface of the steel strand with stable holding force and minimal anchorage retraction, meeting the precision requirements for prestressing operations.
III. Construction and Compatibility Advantages
Ideal for single-point reinforcement, short-span components, and localized prestressing upgrades. It offers greater flexibility than multi-hole group anchor layouts, allowing for distributed placement as needed—perfect for confined spaces such as floor slabs, pool sidewalls, and small beams or columns.
Compatible with the two most common PC steel strand sizes (12.7mm and 15.2mm), serving as a versatile component for unbonded prestressing projects in civil construction.
Convenient post-tensioning corrosion protection
The anchor assembly features a uniform overall profile; once tensioning is complete, the trumpet-shaped opening can be directly sealed with mortar. This simple sealing process effectively prevents moisture-induced corrosion of the steel strands and wedges.
