1. Company Overview

Jiangsu Bailey Steel Bridge Co., Ltd., established in 2006, is a leading specialized manufacturer and solution provider of Bailey steel bridges in China. With nearly two decades of industry expertise, the company operates a modern production base spanning over 10,000 square meters, boasting a monthly production capacity exceeding 2,500 tons. Certified under the ISO 9001:2015 Quality Management System and rigorously vetted through SGS in-depth supplier audits, our products are distributed across all five continents globally.  

2. Bailey Bridge: History and Principles

The Bailey Bridge, invented by British engineer Donald Bailey during the early years of World War II, is fundamentally a truss bridge system rapidly assembled using standardized modular components. This design philosophy remains the gold standard in emergency engineering and temporary bridge construction.  

Core Principle: Standardized "panels" serve as the basic truss units, connected swiftly via "pins." By varying the number of "rows" and "layers" of the trusses and incorporating "reinforcing chords," the system can be flexibly configured to meet diverse span and load requirements.  

3. Key Products and Technical Standards

We specialize in producing the two most widely used Bailey bridge models globally, adhering strictly to international standards.  

• Primary Models:  

• "321" Type Steel Bridge (commonly referred to as "100" Type in China): A classic imperial-dimension model renowned for its versatility.  

• "200" Type Steel Bridge: A metric-dimension model with an increased truss height of 2.134 meters, offering superior bending and shear resistance. It is the mainstream choice for large international projects.  

• Materials and Processes:  

• Primary Steel: Core load-bearing components such as panels, reinforcing chords, and cross beams are manufactured from high-strength structural steel Q355B.  

• Anti-Corrosion Treatment: Military-grade hot-dip galvanization is available, with zinc coating thickness exceeding 600g/m², ensuring decades of durability even in harsh environments.  

• Design Standards: Our bridges comply with multiple international load specifications, including American AASHTO HS25/HL-93, British Standard HA, and Indian IRC Class A.  

4. Component Composition

A complete Bailey bridge system consists of the following standardized components:  

• Main Truss: Panels, panel pins, reinforcing chords, chord bolts.  

• Deck System: Cross beams, beam clamps, steel deck panels, wind bracing, curbs.  

• Connection Parts: Support frames, splice plates, end posts (male and female).  

• Bearings: Bridge seats, base plates.  

5. Global Applications and Project Examples

Leveraging exceptional product quality and 19 years of export experience, our Bailey bridges play critical roles in vital engineering projects worldwide.  

• International Projects:  

• Asia: Contributions to Cambodia’s Kamchay Hydroelectric Power Station, a 75-meter double-row reinforced steel bridge in Mindoro, Philippines, a 2,000-ton export project for 108 bridges in Myanmar, and post-earthquake reconstruction in Nepal.  

• Africa: Bridges supplied for UN peacekeeping forces in Kenya, alongside infrastructure projects in Nigeria, Angola, Congo, and Sudan.  

• South America: Exports to countries including Venezuela.  

• Domestic Projects:  

• Widely deployed in complex geographical environments such as Tibet and Xinjiang for transportation line construction. As a qualified supplier to major state-owned enterprises like China Railway, our bridges are used for construction temporary bridges and cast-in-place beam support systems in railway and highway projects.  

6. Installation and Technical Services

The Bailey bridge excels in rapid installation. The standard method, "rolling launch technique," involves assembling the bridge onshore, attaching a launching nose at the front, and smoothly pushing it across the gap using rollers.  

We go beyond product supply by offering comprehensive technical support. Our experienced engineers can be dispatched to project sites anywhere in China or globally to provide professional installation guidance and technical consulting services.  

Key Features Highlighted:  

• Modular Design: Ensures quick assembly, disassembly, and reusability.  

• Adaptability: Customizable for various spans (e.g., 9m to 60m+) and loads (e.g., HS25-44).  

• Durability: Galvanized components resist corrosion, extending service life beyond 15 years.  

• Global Compliance: Meets ISO, AASHTO, BS, and IRC standards.
