· ​Superior 1860 MPa Tensile Integrity: Premium high-carbon steel wire rods deliver maximum ultimate breaking load capability, allowing structural engineers to optimize tendon configurations in post-tensioned designs.
· ​Active Zinc Galvanized Defense: Uniformly coated with a high-purity zinc protective layer, offering sacrificial anode protection and an impermeable barrier against atmospheric oxidation and moisture infiltration.
· ​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.
· ​Full Metallurgical & Protective Traceability: Manufactured under strict ISO 9001 protocols. Each commercial shipment includes a comprehensive Mill Test Certificate (MTC) verifying tensile strength, elongation, and zinc coating mass.
​Engineered for heavy-load-bearing post-tensioned structures across global civil and infrastructure sectors:
· ​Bridge Engineering: Cable-stayed bridges, suspension bridge stay cables, external post-tensioned box girders, and precast segmental viaducts.
· ​Heavy Civil Structures: Nuclear containment vessels, LNG concrete storage tanks, and large-scale industrial foundation systems.
· ​Marine & Geotechnical Works: Port wharfs, offshore platforms, high-capacity ground anchors, and slope stabilization structures.
​Q: How does this high-tensile galvanized strand perform in post-tensioned systems?
A: It provides a dual advantage: the 1860 MPa core delivers the massive tensile force required for post-tensioned load paths, while the heavy zinc coating protects the steel against corrosion in exposed or aggressive environments.
​Q: Do these strands comply with international manufacturing standards?
A: Yes. The base mechanical properties comply strictly with ASTM A416, BS 5896, or ISO 6934-4, and the galvanization meets relevant international standards such as EN 10244 and ASTM A475.
​Q: What is the standard export packaging and transport safety?
A: Coils are wrapped in heavy-duty moisture-proof materials, secured with high-tensile steel strapping, and palletized to prevent zinc coating abrasion during international containerized transport.
