ICF(Insulated Concrete Form) Bracing
Custom Engineered Steel Plate Girder Bridges: AASHTO, EN & AS Standards Compliant
Our Steel Plate Girder Bridges are the cornerstone of modern infrastructure, providing a robust solution for medium-to-long span crossings. As a premier China Steel Bridge Factory, we deliver Prefab Steel Structures that combine high tensile strength with rapid on-site assembly. Whether for highway overpasses or railway viaducts, our girders are precision-fabricated to handle heavy dynamic loads while minimizing construction time.
We function as a complete Steel Structure Building partner, managing the lifecycle from detailed engineering to final delivery. Our production adheres strictly to the American Association of State Highway and Transportation Officials Load and Resistance Factor Design (AASHTO LRFD) specifications, ensuring safety and reliability for critical infrastructure projects globally.
