Truss Steel Bridge

Product Overview

The Truss Steel Bridge is a classic and highly efficient bridge structure composed of interconnected steel members forming triangular units. This structural form provides excellent strength, stability, and load distribution, making it ideal for medium to long spans under heavy traffic or complex site conditions.

Truss steel bridges are widely used for:
Highway and roadway bridges
Railway bridges
Pedestrian and bicycle bridges
Industrial and mining transport bridges
Temporary and emergency bridges

Common truss types include:
Through Truss Bridge
Deck Truss Bridge
Half-Through (Pony) Truss Bridge
Warren Truss / Pratt Truss / Howe Truss

Key Advantages

High Load-Bearing Efficiency
Triangular truss system effectively transfers loads, suitable for heavy vehicles and trains.

Long-Span Capability
Ideal for spans typically ranging from 20 m to 150 m or more.

Excellent Structural Stability
Strong resistance to bending, vibration, wind, and seismic forces.

Lightweight Compared to Concrete Bridges
Reduces foundation loads and construction costs.

Fast Fabrication & Installation
Prefabricated steel members enable rapid erection on site.

Durable & Long Service Life
Advanced corrosion protection ensures a design life of 50–100 years.

Easy Inspection & Maintenance
Open structure allows convenient access for inspection and repair.
