Product Details

Our prefabricated steel‑structure highway bridge is engineered for highway overpasses, river‑crossing bridges and road reconstruction projects. Adopting steel I‑girder, box girder or steel truss systems, this heavy‑load steel bridge satisfies the load requirements of large‑volume highway passenger and freight vehicles.

All steel members are precisely pre‑produced in‑house with Tekla structural modeling. Welding quality, dimensional tolerance and anti‑corrosion surface treatment are strictly inspected before delivery. Modular components enable fast assembly on‑site, greatly shortening construction period and minimizing disturbance to existing traffic.

The steel highway bridge delivers outstanding seismic performance, wind resistance and environmental adaptability. Multi‑layer anti‑corrosion paint system protects steel components against humidity, salt spray and temperature variation. We can fabricate according to AASHTO, Eurocode, ASTM and other international standards, providing full material certificates and inspection documents for overseas tender projects.

We supply full‑set services including structural deepening design, steel fabrication, surface treatment, packing and on‑site installation technical guidance. Our engineering team has rich experience in large‑scale transportation infrastructure projects. Custom design is available based on your span requirement, traffic load, local climate and project budget.
