· ​100% Load-Transfer Continuity: Engineered to match or exceed the ultimate breaking load of the connected PC strands, ensuring seamless stress transmission across the splice joint without structural reduction.
· ​Dual-End Precision Wedge Locking: Features symmetrically opposed internal chambers equipped with precision-matched high-carbon steel wedges that bite securely onto both strand ends simultaneously.
· ​High-Strength Forged Alloy Body: Crafted from superior forged alloy steel with advanced thermal treatment, providing exceptional fatigue resistance and structural rigidity under continuous dynamic loads.
· ​Full Batch Traceability & QC: Manufactured under strict ISO 9001 quality frameworks. Each production lot undergoes proof-loading, hardness verification, and rigorous dimensional inspection.
​Essential mechanical splicing components deployed across heavy civil and structural engineering sectors:
· ​Bridge Construction & Rehabilitation: Segmental bridge extension, box girder tendon repairs, and staged post-tensioning connection works.
· ​Building & Slab Modification: Structural strengthening, column/wall retrofitting, and long-span transfer beam tendon splicing.
· ​Specialized Geotechnical Works: Extended ground anchors, rock stabilization tethers, and long-line pre-tensioning bed setups.
​Q: Can this coupler be used for both 0.5" and 0.6" strands?
A: Couplers are precision-machined for specific strand diameters. We offer dedicated models tailored precisely for either 12.7 mm (0.5") or 15.24 mm (0.6") strands to ensure a flawless wedge grip.
​Q: Does the coupler maintain 100% of the strand's breaking strength?
A: Yes. When properly installed with matching high-strength wedges and clean PC strands, the coupler transfers 100% of the guaranteed ultimate tensile strength (GUTS) of the tendon.
​Q: What is the standard export packaging and transport safety?
A: Coupler bodies and matched wedge sets are coated with anti-rust oil, packed in heavy-duty moisture-proof bags, and boxed inside robust export cartons to prevent transit contamination.
