· ​Symmetric Multi-Tendon Locking: Features precision-machined individual conical bores that ensure uniform 360-degree wedge seating for every individual strand, guaranteeing absolute slip-resistance under ultimate tension.
· ​High-Strength Metallurgical Integrity: Cast and forged from superior ductile iron or alloy steel, providing exceptional compressive strength and structural rigidity to safely absorb concentrated tendon forces.
· ​Optimized Stress Diffusion (Spiral Cages): Paired with engineered spiral reinforcement cages that effectively confine local high-pressure bearing stresses, preventing concrete splitting or crushing behind the anchor block.
· ​Full Batch Traceability & QC: Manufactured under strict ISO 9001 quality frameworks. Each production lot undergoes proof-loading, hardness verification, and rigorous dimensional inspection.
​Essential heavy structural components deployed across major civil and building engineering sectors:
· ​Highway & Railway Bridges: Continuous cast-in-place box girders, precast segmental bridges, extradosed bridges, and cable-stayed anchorage zones.
· ​High-Rise & Heavy Commercial Buildings: Massive transfer girders, podium foundation mats, and core-wall post-tensioning systems.
· ​Specialized Heavy Infrastructure: Nuclear containment structures, LNG storage tanks, large-span industrial roofs, and dam stabilization anchors.
​Q: What components are included in a complete multi-strand wedge anchorage assembly?
A: A standard delivery set includes the multi-hole anchor head (plate), matching sets of multi-piece wedges for every strand hole, a steel trumpet, and the matching spiral reinforcement (bursting cage).
​Q: Are these anchorage systems compatible with international post-tensioning standards?
A: Yes. Our multi-strand anchorages are produced and tested in strict compliance with major international standards such as PTI, ASTM, and ISO requirements, ensuring seamless acceptance by global contractors.
​Q: What is the standard export packaging and transport safety?
A: Anchorage components are treated with anti-rust protection, securely packed onto heavy-duty wooden pallets, and fastened with steel strapping to prevent transit damage during international freight.
