Description
Technical Parameters
Main Structures
- Steel truss bridges: Lattice structure, high material utilization, suitable for long-span railway and highway bridges. Precast components are then connected on-site with high-strength bolts.
- Steel box girder bridges: Box-section, high torsional stiffness, suitable for mid-span urban viaducts. Precast components are manufactured in a factory and then welded or bolted on-site.
- Steel-concrete composite beam bridges: Economical and high stiffness. Steel beams are precast components; the bridge deck can be cast on-site or precast.
- Other forms: Steel plate girder bridges, steel arch bridges, and steel main girder segments of cable-stayed/suspension bridges.



Product Advantages
- Fast construction speed: Precast components are already manufactured and can be directly assembled on-site, significantly shortening construction time. Suitable for emergency rescue and projects with tight schedules.
- Convenient quality assurance: Structural components are manufactured in the factory, ensuring controllable quality. Compared to on-site casting, precast components have more uniform and reliable performance.
- High adaptability: Suitable precast steel bridge types and component combinations can be flexibly selected according to different spans, load requirements, and terrain conditions, demonstrating strong adaptability.
- Reusable: Some steel bridges can be dismantled and reused.
Application Scenarios
- Urban Bridges: Typical applications, minimizing impact on urban traffic.
- Railway Bridges: High requirements; prefabricated structures are manufactured in the factory to ensure quality.
- Mountain Bridges: Reduces self-weight and foundation construction, and facilitates component transportation.
- Emergency and Military Engineering: A dominant area for modular steel bridges.
- Rapid Replacement: Old bridges can be dismantled and new prefabricated bridges can be quickly installed.
