Key features

Why anchorages use these wedges

Four properties that decide whether the strand stays gripped through stressing and service.

01

Consistent heat treatment

Case hardened alloy steel held at 58 - 62 HRC, so every wedge in the batch grips the strand the same way through stressing.

02

Long service life

The hardened serrated grip pattern and an anchorage coefficient of 95% efficiency or higher support reliable holding power in service.

03

Interchangeable design

Tri-part and mono wedges are made for 12.7mm and 15.24mm strand, so the same anchorage system can be assembled across the tendon schedule.

04

Batch traceability

Wedges are supplied in traceable production batches, which keeps documentation and repeat orders straightforward.

Technical answer

What are post tension wedges for prestressing anchorage?

Definition

Post tension wedges are the gripping elements that hold the strand inside the anchorage and transfer the prestressing force into the anchor head. Global Overseas manufactures them from case hardened alloy steel to 58 - 62 HRC, in tri-part and mono designs for 12.7mm and 15.24mm strand. Each wedge is precision machined with a serrated grip pattern, and the anchorage system is rated at 95% efficiency or higher, so the strand is held reliably through stressing and service.

Wedges are supplied to EN, PTI or ASTM requirements and are used in post-tensioning anchorage systems where 12.7mm or 15.24mm strand is stressed. Consistent heat treatment keeps hardness in the 58 - 62 HRC band from batch to batch, and batch traceability makes repeat orders and documentation straightforward. Because the wedge must match the anchor head and the strand it grips, buyers should state the strand size, wedge type (tri-part or mono), required standard, hardness, quantity, packing and destination port when requesting a quotation.

Specification

What to state in the RFQ

Strand size (12.7mm or 15.24mm), wedge type (tri-part or mono), material and hardness, standard (EN, PTI or ASTM), quantity, packing method, destination port and any batch traceability or inspection requirement.

Compatibility

Compatibility

Confirm the anchor head and strand the wedge will grip before ordering. Wedge selection must follow the project engineer’s drawings and the anchorage supplier’s compatibility requirements.
