- High strength and significant stiffness with reduced beam height and self-weight compared to concrete bridges
- Steel isotropic properties ensure uniform material quality and predictable performance
- Factory prefabricated components with on-site assembly using pins and bolts
- Short construction period with minimal seasonal impact
- Suitable for industrialized manufacturing and easy transportation
- Easy maintenance and replacement with recyclable materials
Beam bridges, arch bridges, rigid frame bridges, cable-stayed bridges, suspension bridges, and pedestrian footbridges for parks, walkways, and public spaces.
Temporary bridges, emergency bridges, fixed bridges, and suspension bridges of varied spans. Modular steel bridges offer increased truss panel height and larger sections for enhanced load capacity compared to traditional Bailey bridges.
