ICF(Insulated Concrete Form) Bracing
AASHTO Eurocode AS5100 Certified Modular Steel Bridge Engineering & Fabrication
A Modular Steel Bridge, also referred to as Prefabricated Steel Bridge or Bailey Bridge, consists of standardized factory prefabricated steel components assembled on site through bolted or pinned connections. As core Prefab Steel Structures, it eliminates complicated cast-in-place work, shortens construction cycles, and lowers overall project investment.
Our modular steel bridge adopts high-strength structural steel and premium Galvanized Steel Bridge anti-corrosion treatment, adapting to urban, coastal, mining, rural and various harsh environments. Featuring lightweight structure, high load capacity and excellent stability, it serves as an ideal alternative to traditional concrete bridges for temporary and permanent infrastructure construction.
Design Standards & Compliance
All products follow mainstream global engineering codes including AASHTO LRFD 2020 (American Association of State Highway and Transportation Officials Load and Resistance Factor Design Specification), EN 1993 (Eurocode 3) (Design of Steel Structures), AS 5100 (Australian Bridge Design Standard), and GB 50017-2017 (Code for Design of Steel Structures, Chinese National Standard). Raw materials comply with ASTM A709 (Standard Specification for Structural Steel for Bridges) and EN 10025 (Hot Rolled Structural Steel Products) specifications, while welding execution strictly follows AWS D1.5 (American Welding Society Bridge Welding Code) requirements to ensure overall structural safety and smooth project acceptance worldwide.
Main Structural Types & Features
We supply diversified structural types to match different span, load and scene demands, all customized as Prefab Steel Structures and rigid Steel Frames:
- ● Truss Modular Steel BridgeLightweight space framing layout, strong spanning capability, suitable for medium and long-span river crossing, railway overpass and scenic landscape projects. Good stability with less foundation investment.
- ● Plate Girder Modular Steel BridgeSimple structure, economical cost and convenient transportation and installation. Widely used for short-span municipal road crossing, park trails and temporary construction access.
-
● Box Girder Modular Steel BridgeHigh torsional stiffness, low vibration and modern appearance, perfect for urban core areas, heavy pedestrian flow and long-span permanent passage projects with superior walking comfort and durability.
