Our modular steel bridge consists of standardized prefabricated steel units manufactured in our workshop. Adopting modular splicing connected entirely by high-strength bolts without any on-site welding, it achieves quick deployment, easy disassembly and repeated reuse. With lightweight structural features, it brings low load pressure on foundations and adapts perfectly to soft soil, mountainous and complex geographical environments. Widely used in temporary passages, emergency construction and light-duty permanent infrastructure across the world, the bridge is equipped with durable anti-corrosion treatment and complete export supporting services.
Modular Steel Bridge Designs
✅Bailey Truss Modular Bridge
It is the most widely recognized modular bridge system in global civil engineering. Composed of interchangeable standard truss panels, it supports flexible span expansion and strong crossing capacity. It is especially ideal for disaster relief, emergency passages and temporary traffic crossing projects.
✅Light Girder Modular Bridge
Made of prefabricated I-shaped steel beam modules, it features simple structure, cost efficiency and the fastest on-site assembly speed. It is suitable for short-span construction access roads, rural passages and mixed pedestrian-light vehicle temporary traffic.
✅Integrated Composite Modular Bridge
Integrates prefabricated steel frames with integral composite bridge decks, providing better overall rigidity and longer service life. It is perfectly applied to semi-permanent and long-term projects such as mining transportation routes and rural permanent traffic infrastructure.
