Product Description
Steel Box Girder Bridge Overview
Custom engineered steel box girder bridges designed for exceptional load capacity and structural stiffness. These bridges feature advanced orthotropic steel bridge panels and precision manufacturing for superior performance.
Structural Composition
Each bridge consists of:
- Top plate (bridge panel) with thickness 12-30mm
- Beam web with thickness 12-30mm
- Bottom plate with thickness 12-30mm
- Longitudinal stiffeners with thickness 10-20mm
- Transverse stiffeners with thickness 10-20mm
- Diaphragm plates (cross beams)
Manufacturing Process
Factory-manufactured sections (10-30m lengths) with site welding assembly. Strict quality control ensures weld integrity and structural reliability.
Bridge Types & Applications
Single Box Steel Beam Bridge:
- Steel deck with beam spacing 1.5-3m (open rib) or 2-4m (closed rib)
- Ideal for bridge widths up to 3 lanes or width-to-span ratio
- Double width single box girder available for 4-6 lanes
Double Box Steel Girder Bridge:
For larger bridge widths where single box becomes impractical or uneconomical.
Multi-Box Steel Girder Bridge:
Optimal for smaller spans with large bridge widths, ensuring uniform load distribution.
Structural Advantages
- Large flange width for superior bending resistance and long spans
- Exceptional torsional stiffness suitable for curved bridges
- Enhanced transverse flexural strength with reduced need for connections
- Compact beam height for limited building height applications
- Hollow structure facilitates easy maintenance and utility installation
