Product Positioning

Focused on steel truss bridges for heavy-duty railways, mining passages, and long-span highway bridges, offering three types of web member arrangements: Warren, Pratt, and Double Diagonal, suitable for spans ranging from 30–150 meters, supporting both welded joints and fully bolted connections.

Core Advantages

Members mainly bear axial forces, resulting in high material efficiency; employing segmental prefabrication, overall lifting, or cantilever assembly methods, no support is needed under the bridge, allowing it to cross deep valleys and existing lines without interrupting operations.

Global Compliance

Strictly meets mainstream international standards including European standards (EN 1993-1-8 node plate buckling and EN 1993-2 truss fatigue), American standards (AASHTO LRFD truss slenderness limit and AWS D1.5 welding), and Australian standards (AS 5100.4 truss members and AS 4100 compression member stability).

Service Assurance

Provides full-cycle technical support from node plate Whitmore section checks, member slenderness optimization, fatigue detail classification control to pre-assembly schemes and segmented transportation design.

Our steel truss bridge features optimized triangular stress truss system, manufactured for permanent highway passage, river spanning, municipal traffic upgrading and temporary emergency bridge engineering. It balances ultra-large spanning capacity, structural fatigue resistance and outdoor weather durability, fitting diverse complex terrain and long-term heavy traffic operation requirements worldwide.

Our prefabricated steel truss bridge adopts integrated triangular stable steel truss stress system, specially developed for municipal road, river crossing, mountain transportation and traffic reconstruction infrastructure. With reasonable force transmission layout, ultra-long span adaptability and high weather resistance, it satisfies permanent and temporary highway, pedestrian and engineering passage projects, and maintains outstanding structural safety in complex geological and climatic environments.

Our Steel Truss Bridge adopts high-strength hot-dip galvanized steel truss system, professionally designed for highway, pedestrian, railway and municipal crossing engineering. It integrates excellent load-bearing performance, lightweight structure and fast construction, perfectly adapts to river crossing, valley spanning, urban interchange and traffic reconstruction projects. The optimized open truss structure realizes reasonable stress distribution, matches diversified span layout, and maintains stable structural safety under complex natural environments.

Product Positioning:Focused on steel truss bridges for heavy-duty railways, mining area passages, and long-span highway bridges, offering Warren, Pratt, and Double-diagonal truss configurations. Suitable for spans ranging from 30 to 150 meters, supporting both welded connections and fully bolted connections.

Core Advantages:Members are primarily subjected to axial forces, resulting in high material efficiency; employing segmental prefabrication, overall lifting, or cantilever assembly methods, no support is needed under the bridge, allowing it to cross deep valleys and existing lines without interrupting operations.

Global Compliance:Strictly meets mainstream international standards including European standards (EN 1993-1-8 node plate buckling and EN 1993-2 truss fatigue), American standards (AASHTO LRFD truss slenderness limit and AWS D1.5 welding), and Australian standards (AS 5100.4 truss members and AS 4100 compression member stability).

Service Assurance:Provides full-cycle technical support from node plate Whitmore section verification, member slenderness optimization, fatigue detail classification control to pre-assembly schemes and segmented transportation design.

Strong load-bearing capacity:Composeearing Capacityd of triangular truss units, with reasonable force distribution, suitable for heavy loads and large-span scenarios.

High Stiffness, Low Deformation:The overall structure has good stability, deflection is small under dynamic loads, and vehicular movement is smooth.

Convenient for Prefabrication and Rapid Assembly:Components can be factory-produced, connected on-site with bolts or welding, resulting in a short construction period.

High Material Utilization but High Maintenance Requirements:The members are mainly subjected to tension or compression, making steel economical; however, the joints are prone to fatigue, requiring frequent anti-corrosion coating maintenance.
