The steel rigid frame bridge combines beam and arch structural systems, featuring an integrated bent upper beam structure and pressure-bearing lower column. This rigid connection between beam and column provides exceptional load distribution, creating a compression-bending and thrust structure ideal for heavy-duty applications.

Primary load-bearing structure composed of upper chord, lower chord, and belly rod components including diagonal and vertical bars. Nodes are categorized as large and small with defined pitch distances.

Longitudinal and horizontal connections that transform the bridge into a stable space structure capable of withstanding various lateral loads including wind, rocking forces, and centrifugal forces.

Comprising longitudinal beams, cross beams, and connections that efficiently transfer loads from the deck to the main truss structure.

• Large span capabilities up to 300 meters
• Rapid construction with prefabricated sections
• Energy-efficient manufacturing process
• Superior seismic performance
• Customizable designs for specific applications
• Wide application range for road, rail, and pedestrian use

Simple structure with fixed design parameters for easy installation and manufacturing.

Distributes shear forces across multiple diagonal rods, ideal for large spans requiring lightweight, dismountable structures.

Optimized for large spans with short compression inclined rods that enhance buckling stability and simplify joint arrangements.

• Railroad Bridges for standard gauge and light rail systems
• Pedestrian Bridges providing safe crossings for pedestrians and cyclists
• Road Bridges with capacities up to 100-ton trailers
• Custom infrastructure projects requiring large spans
