Custom Steel Truss Bridges for Road, Railway, Pedestrian and Industrial Crossing Projects：
Steel truss bridges use a triangulated structural system to transfer loads efficiently across the span, making them suitable for projects requiring high structural capacity, relatively long spans and efficient use of steel.
They can be used for highway crossings, railway bridges, pedestrian bridges, industrial access routes, river crossings and other infrastructure projects.
Depending on the span, bridge width, design loads, site conditions and transportation requirements, the truss configuration, member sections, deck system and connection method can all be customized for the project.
We can manufacture steel truss bridge structures according to approved drawings and technical specifications, with attention to fabrication accuracy, welding quality, connection details, corrosion protection and transportable segmentation.
What Are Steel Truss Bridges Used For?Steel truss bridges can be used in a wide range of transportation and infrastructure projects, including:
- Highway bridges
- Road bridges
- Railway bridges
- Pedestrian bridges
- Municipal overpasses
- River crossing bridges
- Industrial access bridges
- Mining access bridges
- Water conservancy bridges
- Temporary or project access bridges
A truss bridge can be adapted to different traffic and loading conditions.
For example, a pedestrian bridge may use a relatively lightweight truss system, while a highway or railway bridge may require heavier members, stronger connections and greater structural stiffness.
The structural configuration should therefore be selected according to the actual span, load, bridge width and use.

What Do Steel Truss Bridge Customers Usually Care About?Can the Bridge Meet the Required Span and Load?
This is usually the first consideration.
The steel truss system needs to be selected according to:
- bridge span;
- traffic or railway load;
- bridge width;
- deck weight;
- local wind conditions;
- seismic requirements;
- and other project loads.
Larger spans or heavier loads generally require stronger chords, diagonals, cross beams and connection systems.
Which Truss Configuration Should Be Used?
Different projects may use different truss arrangements.
Common options include:
- Through truss
- Deck truss
- Pony truss
- Pratt-type truss
- Warren-type truss
- Customized truss systems
The appropriate configuration depends on the span, clearance, deck position and architectural requirements.
How Is the Bridge Deck Integrated with the Truss?
The bridge deck may use:
- steel deck systems;
- reinforced concrete decks;
- steel-concrete composite decks;
- or other project-specific systems.
The deck, cross beams and main trusses need to work together as one structural system.
How Are Large Bridge Sections Transported?
Steel truss bridges are often too large to ship as one complete unit.
The bridge can therefore be divided into transportable sections or members according to:
- container dimensions;
- break-bulk shipping;
- road transport limitations;
- lifting capacity;
- and site erection conditions.
Connection locations should be considered during detailing so that field assembly is practical and accurate.
How Is Corrosion Controlled?
Bridge steel structures are exposed to outdoor environments for long periods.
Depending on the project location, corrosion protection may include:
- multi-layer protective paint systems;
- zinc-rich primers;
- metallizing;
- galvanizing for suitable components;
- or other specified protective systems.
Projects in coastal, humid or aggressive environments may require higher corrosion-protection standards.
Structural Requirements for Steel Truss Bridges：Main Truss System
The main truss normally consists of:
- upper chords;
- lower chords;
- diagonal members;
- vertical members;
- and connection nodes.
These members transfer loads through axial tension and compression.
Cross Beams and Floor System
Cross beams connect the main trusses and support the bridge deck.
Their spacing and section size depend on:
- bridge width;
- deck system;
- traffic load;
- and structural arrangement.
Lateral and Sway Bracing
Bracing is important for overall stability.
Depending on the bridge configuration, the structure may include:
- top lateral bracing;
- bottom lateral bracing;
- sway bracing;
- portal bracing.
These systems help resist lateral loads and stabilize the main trusses.
Connection Design
Connections are critical in steel truss bridges because multiple members often meet at concentrated nodes.
Typical connection methods include:
- high-strength bolted connections;
- welded connections;
- gusset plate connections;
- or combined systems.
Connection accuracy directly affects erection and structural performance.
Deflection and Vibration Control
Bridge structures must satisfy not only strength requirements but also serviceability requirements.
For road, railway and pedestrian bridges, the design may need to control:
- vertical deflection;
- vibration;
- fatigue;
- and dynamic response.
Bearings and Expansion Requirements
Bridge movement caused by temperature, loading and structural deformation needs to be considered.
Bearings and expansion systems are coordinated according to the bridge design and support conditions.

Manufacturing According to Customer Drawings：If you already have complete bridge structural drawings, we can manufacture the steel truss bridge according to your:
- structural drawings;
- fabrication drawings;
- material specifications;
- welding requirements;
- coating specifications;
- inspection requirements.
For projects that require further fabrication development, structural details can also be coordinated based on the approved project design.
This is especially important for bridge projects where member geometry, connection nodes, bolt holes and site assembly tolerances must match accurately.
Transportation and Erection Coordination：Large steel truss bridges are normally fabricated and shipped in sections.
Before fabrication, the segmentation can be coordinated according to:
- shipping method;
- container or break-bulk limitations;
- site access;
- crane capacity;
- erection sequence;
- and field connection method.
Components can be marked according to erection drawings to simplify identification during site assembly.
We do not provide on-site installation services, but we can provide:
erection drawings, component marking, installation guidance, technical clarification and remote technical support.
