2. Core Engineering Advantages

· BS 5896 Certified Compliance: Manufactured strictly to meet the mechanical, geometric, and relaxation standards established by British Specifications for prestressed concrete tendons.

· Active Zinc Galvanized Defense: Uniformly coated with a high-purity zinc layer, providing sacrificial anode protection and an impermeable physical barrier against coastal moisture and chemical agents.

· Optimized Low-Relaxation Performance: Advanced thermal-mechanical stabilization restricts stress relaxation to a maximum of 2.5% at 1000 hours, ensuring permanent prestressing force retention over extended lifecycles.

· High Breaking Load Integrity: Premium high-carbon steel wire rods deliver an impressive 183.8 kN minimum breaking load, guaranteeing maximum structural safety factors in demanding designs.

3. Industrial & Bridge Applications

Engineered for heavy-load-bearing structures across global markets utilizing British Standards:

· Bridge Infrastructure: Highway and railway bridges, cable-stayed bridge stay cables, viaducts, and precast segmental girders exposed to high humidity.

· Marine & Coastal Projects: Port wharfs, piers, offshore platforms, and coastal retaining walls subject to salt spray.

· Aggressive Civil Environments: Industrial foundations, wastewater treatment structures, and structures exposed to de-icing salts.

4. Frequently Asked Questions (FAQ)

Q: Do these galvanized strands fully comply with BS 5896 specifications?

A: Yes. Our 12.7mm galvanized strands are produced in strict compliance with BS 5896 (and equivalent EN standards), ensuring seamless acceptance by international consultants and main contractors.

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.
