Steel cable suspension bridges combine the stress characteristics of both cable and beam systems, featuring a flexible suspension combination with main cable and stiffened beam components. These structures are ideal for spans exceeding 1000m and offer exceptional loading capacity for various applications.

Our suspension bridges consist of several key components working together:

• Bridge Tower: Primary load-bearing structure resisting vertical loads
• Main Cable: Core load-bearing element transmitting forces to anchors

Loads are efficiently transmitted from slings to the main cable, then to anchors, piers, and towers. Both main cable and stiffened beam share force distribution under external loading conditions.

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

• Structural Forms: Rigid tower, flexible tower, and rocking column tower
• Cross Bridge Forms: Truss type, rigid frame type, and mixed type structures

Available in multiple structural forms including steel truss beams, steel box beams, concrete beams, and steel-mixed composite beams.

• Single-span suspension bridge
• Three-span suspension bridge
• Four-span suspension bridge
• Five-span suspension bridge

• Ground Anchorage: Main cable tension transferred to foundation via gravity or tunnel anchors
• Self-Anchoring: Main cable tension transmitted directly to stiffening beam

• Increased concrete protective layer thickness
• High-performance durable concrete
• Protective coatings and sealing layers
• Cathodic protection systems

• Paint coating systems
• Thermal spray zinc/aluminum coatings
• Weathering steel applications

• River Crossings: Span wide rivers with minimal environmental impact
• Iconic Landmarks: Architectural structures enhancing city identity
• Long-Span Bridges: Ideal for distances exceeding 1000m without intermediate supports

• Exceptional span capacity for bridges over 1000m
• Superior seismic performance characteristics
• Aesthetically pleasing lightweight appearance
• Excellent visual perspective and sight lines
