Product Description
Large Flexural Stiffness Steel Box Girder Bridge
Our steel box girder bridges feature exceptional flexural stiffness and torsional resistance, making them ideal for highway applications, railway systems, and long-span infrastructure projects.
Structural Components
The steel box-girder bridge consists of top plate (bridge panel), beam web, bottom plate, longitudinal stiffeners, transverse stiffeners, and diaphragm plates (cross beams).
Material Specifications
