Modular Steel Bridge Description: 

The GWD-Type bridge originated in Germany and was introduced into China for mass production through the analysis of its structure by Evercross Bridge engineers.

The introduction of GWD-Type bridge stems from the technical barriers and deficiencies of Bailey Bridge. As is known to all, Bailey Bridge is a common prefabricated steel bridge structure, which is the upper and lower bearing bridge beam with the single pin connecting truss unit as the main beam of the bridge span structure, which has the advantages of simple structure, strong adaptability and good interchangeability. But even if the load is not large, it can only reach 60 meters per single span.Therefore, Evercross Bridge launched the GWD-Type bridge. Although the truss adopts larger steel, the structure is simpler, which not only has the advantage of strong adaptability of prefabricated Bailey steel bridge, but also makes up for the limit of span, improves the length of single span and saves the cost of bridge pier.

Typical Components of a Modular Steel Bridge

Advantages of Modular Steel Bridge :

1. Flexibility and Adaptability

• Customizable Modules: Easily modified or expanded by adding/removing sections, allowing the bridge to adapt to changing traffic needs or route adjustments.
• Portable and Reusable: Modules can be disassembled, transported, and reassembled in new locations, ideal for temporary or emergency infrastructure (e.g., disaster relief, military applications).

2. Cost-Effective

• Reduced Labor Costs: Factory pre-fabrication streamlines production, reducing on-site labor requirements and associated costs.
• Lower Maintenance: Steel’s durability reduces long-term maintenance expenses compared to materials like concrete (e.g., fewer repairs for cracks or erosion).
• Value for Money: While upfront costs may be higher than some alternatives, long-term savings in maintenance and lifespan justify the investment.

Transportation and storage of CD type steel structure bridges

1) When shipping components, the paint film should be damaged, and the components should be prevented from colliding with each other and deforming during loading, transportation and unloading.

2) Components should be transported by various forms of transportation. Regardless of which form is used, intermediate transshipment should be reduced.

3) When shipping components, the manufacturer should provide users with product quality certificates, product component lists, and instructions for use of steel bridges. 

Modular Steel Bridge Advantage

1. Low Maintenance Requirements

• Corrosion Protection: Modern coatings (e.g., zinc plating, epoxy paints) enhance steel’s resistance to rust and corrosion, reducing the need for frequent maintenance.
• Easy Inspections: Modular designs allow for straightforward inspection of individual components, enabling early detection and repair of issues.

2. Applications Across Industries

• Civil Engineering: Used for road and rail bridges, pedestrian crossings, and highway overpasses.
• Military and Emergency Response: Rapid-deployment bridges for military operations or disaster relief (e.g., replacing damaged infrastructure quickly).
• Temporary Structures: Ideal for construction sites, events, or temporary traffic diversions.

Mixture form to erect all kinds of Modular Steel Bridge

Temporary Bridges, Emergency Bridges and Fixed Bridges.
Using the bridge equipment, the suspension bridges of varied span can be erected.
The bridge has the advantages of few components, light weight and low cost.
Modular steel bridge is similar to the panel bailey bridge from their appearance. The difference is its increased truss panel height and truss panel section is larger to afford more loading. Pre-arch method is used to additionally cut down mid-span and vertical deflection to a larger degree.
The components are connected by connecting plates and fixed with high-strength bolts. Modualr steel bridges has all the advantages of Bailey bridge, and with a larger span and stronger load-bearing capacity.
