Product Details

Our prefabricated steel structure bridge serves as a mature modular transportation infrastructure solution for global projects. All primary components such as steel girders, trusses, support systems and connecting accessories are precisely manufactured inside our factory under strict quality monitoring. After complete inspection, finished components are delivered to the construction site for quick splicing and installation.

We support full customization of various bridge types, including steel truss bridges, steel box girder bridges, I-beam steel bridges, pedestrian bridges, highway and light railway steel bridges. Widely applied in urban overpasses, river-crossing passages, mountain transport routes, temporary engineering access bridges and old traffic facility renovation projects.

Hot-dip galvanizing, epoxy primer and topcoat anti-corrosion systems are optional for all steel members. These treatments effectively resist rust, salt fog, humid weather and harsh outdoor environments to guarantee long-term stable operation.

Compared with conventional concrete bridges, steel structure bridges own lighter dead load and higher material efficiency. The lower foundation load helps save investment, especially suitable for areas with weak geology and complicated landforms. Modular construction cuts on-site wet operations, lowers construction noise and waste, making the project easier to satisfy environmental standards.

We supply one-stop engineering service including structural calculation, drawing optimization, component fabrication, field installation guidance and long-term maintenance consultation. All designs follow international steel structure standards. We can deliver tailor-made, economical and safe steel bridge solutions whether you require short-span pedestrian crossings or large long-span traffic bridges.
