HD200 Bailey Bridge
BAILEY
Q345B-Q460C
The large-span Bailey Steel Bridge is a high-quality modular bridge engineered to address the demands of major infrastructure projects requiring reliable cross-span connectivity. As a high-strength steel bridge, it combines advanced engineering with premium materials to deliver exceptional performance across wide gaps—including rivers, valleys, and highways. This durable modular bridge eliminates the limitations of traditional large-span construction, offering a cost-effective, efficient alternative that maintains structural stability even in challenging environments. Ideal for long-term infrastructure developments, industrial projects, and public works, it meets stringent global standards, making it a trusted choice for engineers and project managers tackling complex cross-span challenges.
The defining feature of this long-span steel bridge is its ability to cover extensive distances without intermediate supports. Its optimized design distributes weight evenly, enabling safe and stable passage across wide gaps while maintaining structural integrity.
Crafted from high-grade, high-strength steel, the bridge withstands heavy loads and frequent use. The material’s inherent robustness ensures it performs reliably in high-intensity applications—from industrial transportation to public infrastructure.
As a durable modular bridge, it resists wear, corrosion, and environmental stressors. The combination of premium materials and meticulous manufacturing ensures the bridge maintains performance over extended periods, reducing long-term maintenance costs.
The bridge’s mechanism is built around a robust steel truss structure, featuring triangular configurations that enhance rigidity and load-bearing capacity. This design efficiently disperses forces across the entire structure, minimizing stress on individual components and enabling large-span coverage.
Critical connection points are engineered with reinforced components, ensuring secure assembly and uniform load transfer. The modular connections are designed for strength and stability, even under heavy loads or dynamic traffic conditions.
The mechanism includes adaptive foundation interfaces, allowing the bridge to integrate with various foundation types—including concrete piers and steel supports. This flexibility enables deployment in diverse terrains, from flat urban areas to uneven rural landscapes.

The production process begins with detailed engineering, where experts use cutting-edge software to design the large-span truss bridge according to project specifications. This phase includes structural analysis, load testing simulations, and optimization for large-span performance.
Using state-of-the-art machinery, factory teams manufacture each component with meticulous precision. From truss panels to connection hardware, every part is crafted to meet strict dimensional and strength requirements, ensuring seamless assembly.
Throughout production, each component undergoes multiple quality checks—including material strength testing, dimensional verification, and structural integrity inspections. This rigorous process ensures the final product meets or exceeds global safety and performance standards.
Before shipment, the bridge is partially assembled in the factory to verify component compatibility and structural stability. This pre-shipment testing identifies and resolves any issues, ensuring smooth on-site installation.
