Our Steel Cable Suspension Bridge represents the perfect combination of strength and flexibility, featuring a sophisticated suspension system composed of a main cable and stiffened beam that combines the stress characteristics of both cable and beam structures.

• Catenary Curve Design: Steel cables follow the natural catenary curve for optimal load distribution and structural efficiency
• Support Towers: Tall pylons designed to withstand vertical and horizontal forces while serving as architectural landmarks
• Secure Anchorages: Massive structures that provide counterforce to balance cable tension
• Advanced Suspension System: Hangers and suspender cables evenly distribute loads across the bridge deck
• Lightweight Flexibility: Engineered to absorb dynamic forces including wind and traffic vibrations

Our suspension bridges feature an optimized load path: from sling to cable, then to anchor, pier, and tower. The main cable serves as the primary load-bearing component, with the bridge tower resisting vertical loads and the stiffening beam ensuring vehicle stability.

We offer two specialized cable configurations:

• Wire Rope Main Cable: 7-strand construction ideal for smaller span bridges
• Parallel Wire Bundle Main Cable: Prefabricated parallel steel wire strands (PPWS method) for accelerated construction

Our bridge towers are available in three structural configurations:

• Rigid Tower: Minimal horizontal displacement at the top
• Flexible Tower: Designed for greater horizontal displacement
• Rocking Column Tower: Hinged single-column structure for smaller spans

Multiple stiffened beam configurations available:

• Steel truss beams
• Steel box beams
• Concrete beams
• Steel-concrete composite beams

By Span Configuration: Single-span, three-span, four-span, and five-span designs available

By Anchoring Method: Ground anchor (gravity or tunnel) and self-anchoring systems

• Highway Bridges: Ideal for spanning large bodies of water or deep valleys
• Railway Bridges: Engineered for heavy loading capacity
• Pedestrian Bridges: Safe, visually appealing crossings for urban and scenic locations

Our systematic construction process includes anchor foundation construction, bridge tower erection, main cable installation, stiffened beam placement, and final deck construction.
