Product Overview
The Railway Steel Bridge is a high-strength, precision-engineered bridge system designed specifically for heavy-load railway transport, including conventional railways, high-speed railways, freight railways, metro/light rail, and industrial rail tracks.
Built with high-strength structural steel (Q355/Q370/Q420/Q460 or ASTM/EN equivalents), railway steel bridges are capable of withstanding heavy axle loads, strong dynamic impact, vibration, and long-term cyclic fatigue, making them one of the most demanding categories in bridge engineering.
Common types include:
Steel Truss Railway Bridge
Steel Plate Girder Railway Bridge
Steel Box Girder Railway Bridge
Steel Arch Railway Bridge
Composite Steel–Concrete Railway Bridge
Modular/Temporary Railway Bridge
