Two-Piece Prestressing Wedges

Our two-piece prestressed wedge is a high-performance anchoring component for post-tensioning systems. With a split two-piece design, it ensures reliable clamping and easy installation. As a core match for single-hole anchor barrels, it works seamlessly with prestressing steel strands for stable force transfer, guaranteeing concrete structure safety and durability.

Optimized Two-Piece Structure: Split design enables easy on-site assembly with steel strands and anchor barrels.

Superior Clamping Performance: Special inner tooth profile enhances gripping force via wedge effect. Forms reliable mechanical interlock after tensioning (no slippage/prestress loss), complying with GB/T 14370 standards.

High-Quality Material & Heat Treatment: Made of 20CrMnTi alloy steel with quenching and tempering. Hardness reaches HRC 59-63, case depth 0.5-0.7 mm, ensuring high tensile strength, wear resistance and stable performance under high prestress and harsh environments.

Wide Compatibility: Multiple specs match various steel strand diameters (12.7mm, 15.24mm, 17.8mm, etc.) and single-hole anchor barrels. Custom solutions available for specific projects.

Cost-Effective & Efficient Construction: Simple structure enables easy installation, reducing labor and time. High consistency ensures stable batch performance, controlling costs while guaranteeing quality.

Widely used in: High-rises, commercial/residential buildings; Highways/railway bridges; Precast concrete components; Tunnels, dams; Industrial plants, large-span workshops; Existing structure retrofitting.

Full-process quality control from raw materials to delivery. Each batch undergoes strict testing (dimensional, hardness, tensile anchoring, fatigue) to ensure quality.
