Steel Portable Bridge For Sale/steel Modular Bridge For Sale
The 200-Type Bailey bridge is constructed using high-strength steel materials, specifically designed to offer enhanced load-bearing capacity and durability. Here are the key materials and their characteristics used in the construction of the 200-Type Bailey bridge:
Materials Used
1. **Steel Panels**:
- The primary material used in 200-Type Bailey bridges is high-strength steel. The panels are typically made from steel grades such as Q235B, Q345B, or customized steel grades to meet specific project requirements.
- The steel panels are designed to be lightweight yet strong, allowing for easy transportation and rapid assembly.
2. **Surface Treatment**:
- The steel components are often treated with hot-dip galvanizing to provide superior corrosion resistance. This process involves immersing the steel in molten zinc, which forms a protective layer that prevents rust and extends the lifespan of the bridge.
- In some cases, the surface treatment may also include priming paint and a finishing coat to enhance durability and aesthetics.
3. **Bolts and Pins**:
- The bridge components are connected using high-strength bolts and pins. These fasteners are designed to withstand significant tensile and shear forces, ensuring the structural integrity of the bridge.
4. **Decking**:
- The bridge deck is typically made from steel sheets or steel gratings. In some applications, wooden planks may also be used for lighter duty bridges.
Technical Specifications
- **Panel Dimensions**: The standard panel size is 3.048 meters (10 feet) in length and 2.134 meters in height.
- **Load Capacity**: The 200-Type Bailey bridge is designed to support various load classes, including HS-15, HS-20, HS-25, and tracked vehicles up to 50 tons.
- **Span and Configuration**: The maximum single span can reach up to 60.96 meters, with the bridge length adjustable in increments of 3.048 meters. It can be configured as a single-lane or double-lane bridge, with clear widths of 3.15 meters, 4.2 meters, and 7.35 meters.
Advantages of Materials Used
- **Durability and Longevity**: The use of high-strength steel and galvanization ensures that the bridge can withstand harsh environmental conditions and has a long service life.
- **Rapid Deployment**: The lightweight and modular nature of the steel components allows for quick assembly and disassembly, making it ideal for emergency response and temporary bridge needs.
- **Cost-Effectiveness**: The materials used in the 200-Type Bailey bridge are designed to be cost-effective, with minimal maintenance requirements over the bridge's lifespan.
In summary, the 200-Type Bailey bridge is constructed using high-strength steel panels, bolts, and pins, with surface treatments like hot-dip galvanizing to enhance corrosion resistance. These materials ensure the bridge's durability, load-bearing capacity, and rapid deployment capabilities.
