The cables for suspension bridges are primarily used in various cable structure systems, including cable nets, cable trusses, cable domes, and hybrid systems such as cable-stayed structures, string structures, cable-arch structures, and suspendomes that combine flexible cables with rigid components. They are also essential for glass curtain wall systems. These structural cables are valued for their aesthetic appeal, innovative anchorage design, and high anchoring efficiency. They contribute to creating lighter, more beautiful, and cost-effective building structures, making them particularly suitable for public venues like airports and stadiums that prioritize visual appeal.
Our structural cable products are designed, manufactured, and certified in strict compliance with a comprehensive framework of authoritative international and Chinese standards. The design process adheres to GB 50739-2011 for composite stainless steel cables and the cable structure design specifications of EN 1993-1-11 (Eurocode 3). Manufacturing and material quality are governed by core standards including GB/T 17101-2019 for bridge cables and ISO 19203 for alloy coatings, supplemented by JG/T 330-2011 for stainless steel cables in curtain walls and JG/T 200-2017 for socket terminations. Furthermore, our quality management system is ISO 9001 certified, and we provide authoritative third-party test reports for anchorage efficiency (≥0.95) and fatigue performance, guaranteeing global reliability and compliance.

1. Superior Structural Performance
High Strength & Lightweight: Exceptional strength-to-weight ratio enables super-long spans, significantly reduces the overall structural weight, and lowers foundation costs.
High Anchorage Efficiency: Innovative anchorage design ensures efficient force transfer, with an anchorage efficiency factor typically exceeding 0.95, guaranteeing safety and reliability.
2. Outstanding Aesthetic Value
Visual Lightness: Slim cable profiles and refined connections minimize visual obstruction, giving buildings a transparent, elegant, and modern appearance.
Design Freedom: Provides architects with broad possibilities for realizing complex and innovative architectural forms.
3. Excellent Durability & Cost-Effectiveness
Long-Term Corrosion Resistance: Two main options are available: Galfan-coated cables and stainless steel cables. The Galfan coating offers 2-3 times the corrosion resistance of conventional galvanization, while stainless steel cables provide permanent corrosion resistance with minimal maintenance.
Economic Efficiency: Optimizes structural design, reducing the consumption of traditional materials like steel, resulting in a more competitive life-cycle cost.
4. Proven Compliance & Certification
Products are designed, manufactured, and tested in strict compliance with authoritative international (e.g., EN, ISO) and Chinese (e.g., GB, YB) standards, ensuring reliability and conformity for global projects.
