| Configuration | Roadway Width | Single Span Range |
|---|---|---|
| Single Lane | 4.2m Standard | 35m-91m |
| Double Lane | 7.35m Standard | 35m-91m |
| Additional Specifications: Custom load design available, Steel or concrete deck options, Paint or hot-dip galvanized surface protection | ||
- High strength and significant stiffness with reduced beam height and self-weight compared to concrete bridges
- Steel isotropic material properties ensure uniform quality and predictable performance
- Factory prefabricated components with on-site pin and bolt assembly
- Short construction period with minimal seasonal impact
- Industrialized manufacturing for easy transportation
- Easy maintenance, repair, and replacement with recyclable materials
Bridge types: Beam, arch, rigid frame, cable-stayed, suspension bridges, and pedestrian footbridges.
Rural & Remote Areas: Ideal for challenging locations with easy transport and minimal equipment requirements.
Pedestrian & Bicycle Bridges: Designed with appropriate width, ramps, and handrails for safety and accessibility.
Available configurations include temporary bridges, emergency bridges, and fixed bridges. The system enables erection of suspension bridges with varied spans, featuring few components, light weight, and cost efficiency.
Enhanced truss panel height and section design provides superior load-bearing capacity compared to traditional panel bridges, with pre-arch method reducing mid-span and vertical deflection.
