Heavy-Duty Steel Box Girder Bridges
Box-girder bridges typically consist of components such as steel beams, steel plates, and steel cables. The bridge is constructed by welding steel plates into a closed box-shaped girder, which is then combined with the bridge deck, guardrails, and other elements to form a complete bridge. High-strength, homogeneous steel is used to create a lightweight yet robust load-bearing structure. Its modular design enables efficient manufacturing and rapid on-site assembly. All major components are machined, welded, treated for corrosion resistance, and inspected for quality at the factory, effectively ensuring product quality.
