· ​Superior 1860 MPa Tensile Strength: Premium high-carbon steel wire rods deliver maximum ultimate breaking load, allowing structural engineers to optimize tendon quantity and reduce overall project costs.
· ​Optimized Low-Relaxation Performance: Advanced thermal-mechanical stabilization minimizes long-term stress relaxation, ensuring permanent prestressing force retention over extended structure lifecycles.
· ​Enhanced Bonding Strength: Precise 7-wire helical geometry creates an optimal mechanical interlock with structural cement grout, eliminating tendon slip in post-tensioned applications.
· ​Full Metallurgical Traceability: Manufactured under strict ISO 9001 protocols. Each commercial shipment includes a comprehensive Mill Test Certificate (MTC) detailing chemical composition and mechanical test logs.
​Engineered for heavy-load-bearing structures across large-scale global civil, energy, and marine projects:
· ​Transportation Infrastructure: Highway and railway bridges, box girders, precast segmental bridges, and elevated viaducts.
· ​Commercial & High-Rise Buildings: Post-tensioned slab systems, parking structures, and large-span industrial roofs.
· ​Geotechnical & Energy Engineering: Ground anchors, rock slopes, dam stabilization, nuclear containment, and deepwater port wharfs.
​Q: What international standards do your 1860 MPa PC strands comply with?
A: Our 1860 MPa steel strands comply strictly with ASTM A416, BS 5896, EN 10138, and GB/T 5224, matching the precise blueprint demands of international engineering contractors.
​Q: What is the standard export packaging and container load?
A: Coils are wrapped in moisture-proof plastic film and heavy-duty anti-rust woven cloth, secured with high-tensile steel strapping, and palletized for secure transport. A standard 20ft container loads approximately 20 to 27 metric tons.
​Q: Can we arrange third-party inspection prior to dispatch?
A: Yes. We fully support independent pre-shipment inspections and audits conducted by recognized global agencies such as SGS, BV, Intertek, or TUV.
