    Product Introduction

    • Custom design: Tailor girder dimension per project span, load and site conditions
    • Factory prefabrication: Complete component processing internally before shipment
    • Full technical support: One-stop service from drawing review to field erection

    Core Product Advantages

    • High torsion resistance: Closed box cross-section disperses multi-direction stress for long-span heavy-load projects
    • Anti-fatigue & seismic: Qualified steel and standard welding prolong service lifespan against repeated loads and shocks
    • Wind resistance: Streamlined profile prevents wind flutter for coastal and open-area construction
    • Quick erection: Pre-finished segments cut on-site construction period and labor cost
    • Custom anti-corrosion: Galvanized or paint coating prevents salt & moisture corrosion, lowering upkeep expense
    • Light adaptability: Low dead weight reduces foundation cost with flexible customized span range
