· ​ASTM A416 Certified Mechanical Performance: The high-carbon steel core is manufactured strictly to meet the strength, elongation, and ultimate breaking load requirements of ASTM A416 Grade 270.
· ​Heavy-Duty Hot-Dip Galvanized Defense: Uniformly coated with a thick layer of high-purity zinc via hot-dip processing, offering robust sacrificial anode protection and an impermeable physical barrier against corrosive elements.
· ​Maximum Load-Bearing Capacity: The 140.0 mm² cross-section and 260.7 kN minimum breaking load provide the heavy-duty tensile performance required for massive bridge spans and structural tie-downs.
· ​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.
​Engineered for heavy-load structures exposed to aggressive environments under ASTM standards:
· ​Major Bridge Infrastructure: Cable-stayed bridges, suspension bridge stay cables, highway viaducts, and precast segmental girders.
· ​Marine & Coastal Engineering: Offshore platforms, port wharfs, piers, and coastal retaining walls subject to saltwater spray.
· ​Aggressive Geotechnical & Civil Projects: High-capacity permanent ground anchors, rock slopes, and dam reinforcement.
​Q: Do these galvanized strands comply with ASTM A416 and galvanization standards?
A: Yes. The base steel strand complies strictly with ASTM A416 Grade 270, and the heavy-duty zinc coating meets relevant ASTM galvanization specifications (such as ASTM A475 / A641), ensuring complete acceptance by international consultants.
​Q: What is the standard export packaging and container load?
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. 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.
