Bridge structures

Typically composed of main girders, deck panels, bearings, hangers, steel cables, and other components, bridge structures come in various forms such as beam bridges, arch bridges, suspension bridges, cable-stayed bridges, and truss bridges.
Modern bridge structures utilize high-strength steel or alloy materials, combined with welding, bolted connections, and prestressing techniques to ensure stability and long service life. Plate thickness and cross-section shapes are customized based on span length and loading requirements. Surface treatments include hot-dip galvanizing, anti-corrosion painting, and weathering steel coatings to resist environmental effects like wind, rain, and salt spray. Bridges are widely used in highways, railways, urban transit, ports, and industrial transport systems.
Efficient bridge design not only fulfills transportation needs but also becomes an integral part of city and natural landscapes, blending engineering technology with architectural aesthetics.
