Prefab Modular Steel Bridge Easy Install Large Span Steel Structure Bridge

Our prefabricated high-stability modular steel structure bridges combine innovation with practical engineering. Designed for large spans, these bridges emphasize lightweight construction, aesthetic appeal, and environmental sustainability.

Main Structure Steel: Hot-rolled section steel including I-beams, H-beams, channel steel and angle steel with regular cross-sections and excellent mechanical properties. I-beams and H-beams provide superior bending resistance for load-bearing components while channel and angle steel serve as ideal support and connection elements.

Steel Plates: Form the foundation for complex bridge components through precision cutting and welding. Available in various thicknesses to meet specific structural requirements - thicker plates for high-stress areas like main towers and bridge piers, thinner plates for deck surfacing.

Welding Materials: High-quality welding rods, wires and fluxes specifically matched to steel grades ensure joint strength, toughness and corrosion resistance equal to base materials. High-strength alloy steel electrodes guarantee performance for critical connections.

Multi-layer coating systems provide comprehensive corrosion protection:

• Primers: Epoxy zinc-rich formulations create impermeable barriers against moisture and oxidation
• Intermediate Coatings: Build thickness and enhance durability
• Topcoats: Acrylic polyurethane finishes deliver weather resistance and aesthetic appeal

• Professional design team creating customized solutions
• Factory-direct processing of premium steel materials
• Lightweight yet high-strength construction
• Superior seismic performance
• Rapid assembly reduces project timelines and costs
• Proven reliability in diverse applications
