· ​Symmetrical Load Distribution: Designed with precision-matched segments that divide the radial clamping force equally around the 15.24 mm strand, eliminating localized crushing and ensuring uniform bite.
· ​Precision-Milled Internal Teeth: Engineered with specialized helical teeth profiles that bite securely into high-tensile 1860 MPa steel wire without shearing, providing certified slip-resistance under ultimate breaking loads.
· ​Advanced Thermal Hardening: Subjected to controlled carburizing and heat treatment processes to achieve a surface hardness of 58–62 HRC, guaranteeing exceptional wear and fatigue resistance under heavy cyclic loads.
· ​Full Batch Traceability & QC: Manufactured under strict ISO 9001 quality frameworks. Each production lot undergoes rigorous proof-loading, hardness testing, and dimensional inspection.
​Essential mechanical locking components deployed across heavy civil and structural engineering sectors:
· ​Bridge & Transportation Infrastructure: Precast box girders, highway T-beams, continuous rigid frame bridges, and stay-cable anchorages.
· ​High-Rise & Heavy Commercial Buildings: Heavy structural transfer girders, massive floor slabs, and multi-story parking structures.
· ​Specialized Heavy Engineering: Nuclear containment structures, LNG tanks, and large geotechnical foundation anchors.
​Q: Are these wedges compatible with standard 15.2mm anchor casting heads?
A: Yes. They are precision-machined to fit standard 15.24 mm (0.6") multi-hole anchor plates, trumpets, and stressing chairs used globally in heavy post-tensioning construction.
​Q: Can these wedges be reused after tensioning?
A: No. Prestressing wedges are designed for single-use (one-time permanent anchoring). Once seated under high tension, the teeth undergo permanent engagement and must not be reused for safety reasons.
​Q: What is the standard export packaging and corrosion protection?
A: Wedges are coated with an anti-rust oil film, packed in matching sets, sealed in heavy-duty moisture-proof bags, and boxed inside robust export cartons to prevent transit corrosion.
