Prestressing Anchor Wedge
What is Prestressing Anchor Wedge?
The Prestressing Anchor Wedge is a key gripping component in post-tensioning anchorage systems. It locks prestressing steel strands inside the tapered bore of the anchor head. After tensioning is completed, the wedge works with the anchor head’s conical surface and grips the strand through its inner serrations, transferring prestressing force securely to the anchorage system and concrete structure. It is suitable for prestressed slabs, beams, bridges, and other post-tensioning applications, with matching options available according to the anchorage system, strand specification, and project requirements.
Product Overview
The Prestressing Anchor Wedge is a key gripping and locking component used in post-tensioning anchorage systems. Installed inside the tapered bore of the anchor head, the wedge moves into the bore with the prestressing strand after tensioning is released. Its tapered profile and internal serrations securely grip the strand, allowing prestressing force to be transferred from the strand to the anchorage system and structural member.
It is suitable for prestressed concrete slabs, beams, bridges, and other post-tensioning applications. Wedge solutions can be matched to different anchorage systems, steel strand specifications, and project requirements for anchorage accessory sourcing, construction maintenance, and bulk supply.
Key Advantages
- Tapered self-locking design: Works with the anchor head's tapered bore to lock the steel strand under load.
- Serrated gripping surface: The internal working surface contacts and grips the prestressing strand for stable force transfer.
- System compatibility: Can be matched to single-hole, multi-hole, round-anchor, and flat-anchor systems.
- Engineering supply support: Suitable for anchorage manufacturers, post-tensioning contractors, bridge contractors, and building-material distributors.
- Custom supply options: Specifications, packaging, and bulk delivery can be discussed based on samples, drawings, or complete anchorage requirements.
Different Sizes, Different Applications
Different wedge sizes are designed for different anchoring requirements. Larger models are used in post-tensioning anchorage systems for gripping and locking prestressing steel strands in applications such as concrete beams, bridge components, and structural tensioning work. Smaller models are suitable for suspended ceiling wire rope tensioning and fixing, where the wedge mechanism helps secure the wire rope within the matching anchor body. Select the appropriate model according to the wire rope or strand specification, anchorage configuration, and project application.

Installation and Matching Guidance
Prestressing anchor wedges should be used with the corresponding anchor head bore, steel strand specification, and tensioning procedure. During installation, the wedge working surface and strand contact area should be kept clean and free of oil, debris, or visible damage that may affect gripping performance. After tensioning, the wedges should be correctly seated inside the anchor head to ensure proper engagement between all load-bearing components.
For bulk engineering projects, providing the anchor head model, steel strand specification, tensioning method, and packaging requirements together helps establish a suitable supply solution.
Frequently Asked Questions
Can prestressing anchor wedges be purchased separately?
Yes. Wedges can be supplied individually as anchorage accessories or together with a complete anchorage system.
How can I determine the correct specification?
Please provide the anchor head type, steel strand specification, wedge sample, or technical drawing for matching.
Is bulk purchasing available?
Yes. Bulk supply is available for engineering projects, with packaging, delivery schedules, and supply arrangements discussed according to order requirements.
