Assembled steel bridge

Description

The Assembled Steel Bridge is a modular, prefabricated, and rapidly deployable bridge system widely used for highways, municipal roads, pedestrian crossings, emergency reconstruction, mining access roads, military transport routes, and temporary or permanent river crossings.

All components—including main girders, trusses, decks, bracings, and connectors—are fully prefabricated in the factory, enabling fast assembly, high structural stability, and excellent load-bearing capacity.

With superior durability and easy installation, assembled steel bridges offer an efficient, cost-effective solution for modern transportation infrastructure.
