· ​EN 10138-3 Certified Compliance: Manufactured strictly to meet the stringent mechanical, geometric, and relaxation requirements of European standards for prestressed concrete tendons.
· ​Massive Load-Bearing Capacity: The 150 mm² nominal cross-section and 279 kN minimum breaking load provide the exceptional tensile strength required for heavy civil engineering.
· ​Low-Relaxation Stability (Class 2): Advanced thermal-mechanical stabilization restricts stress relaxation to a maximum of 2.5% at 1000 hours, ensuring permanent prestressing force retention over extended lifecycles.
· ​Enhanced Bonding Interlock: The precise 7-wire helical geometry creates an optimal mechanical bond with structural cement grout, eliminating slip in post-tensioned applications.
​Engineered for heavy-load-bearing structures across global markets utilizing European design standards:
· ​Major Transportation Projects: Long-span highway/railway bridges, continuous rigid frames, precast segmental girders, and viaducts.
· ​Energy & Heavy Infrastructure: Nuclear containment structures, LNG concrete storage tanks, and industrial foundations.
· ​Geotechnical & Marine Engineering: High-capacity ground anchors, rock slopes, dam stabilization, and deepwater port wharfs.
​Q: Do these strands fully comply with EN 10138-3 specifications?
A: Yes. Our 15.7mm strands are produced in strict compliance with EN 10138-3 (Y1860S7 designation), ensuring complete acceptance by European engineering consultants and main 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. A standard 20ft container loads approximately 20 to 27 metric tons.
​Q: Can we request third-party quality inspection prior to shipment?
A: Yes. We fully support independent pre-shipment inspections and audits conducted by recognized global agencies such as SGS, BV, Intertek, or TUV.
