Product Description
Composite Steel Box Girder Bridge Overview
Our composite steel box girder bridges feature advanced structural designs that combine durability with ease of maintenance. These bridges are engineered for long-span applications across various transportation needs.
Structural Components
The steel box-girder bridge consists of multiple integrated components including top plate (bridge panel), beam web, bottom plate, longitudinal stiffeners, transverse stiffeners, and diaphragm plates (cross beams).
Orthotropic Steel Bridge Panels
Featuring both open and closed longitudinal rib sections, our bridge panels utilize inverted T-shape cross-sections with optimized spacing for maximum structural efficiency.
Bridge Configuration Options
Single Box Steel Beam Bridge
Ideal for bridges with widths up to 3 lanes or width-to-span ratios less than 1/10. Features steel deck construction with beam spacing of 1.5m to 3m for open rib configurations.
Double Box Steel Girder Bridge
Suitable for wider bridge applications where single box designs become impractical. Can be configured with or without additional beam supports.
Multi-Box Steel Girder Bridge
Optimal for applications with small spans and large bridge widths. Features uniformly spaced main beams for even load distribution.
