In the realm of modular bridge construction, few names command as much respect as Zhenjiang Great Wall Heavy Industry Technology Co., Ltd. (hereinafter referred to as Great Wall). As a Professional Bailey Bridge Component Factory, Great Wall has established itself as a leader in the design, production, and export of prefabricated Bailey bridges and modular steel structures. With years of engineering excellence, advanced manufacturing capabilities, and a commitment to innovation, Great Wall continues to set the benchmark for quality and reliability in global bridge component manufacturing.
Situated in the vibrant Yangtze River Delta economic zone, Great Wall benefits from an advantageous geographic location — 30 kilometers from Zhenjiang seaport, 50 kilometers from Changzhou airport, 70 kilometers from Nanjing airport, and 70 kilometers from Yangzhou-Taizhou airport. This logistical convenience ensures efficient international transportation and timely delivery to clients around the world.
The company’s main products include the 321-Type (British Compact-100) prefabricated highway steel bridge and the 200-Type prefabricated highway steel bridge (Bailey Bridge) — both known for their modular design, ease of assembly, and exceptional load-bearing capacity. Great Wall has also developed a new large-span prefabricated D-Type bridge, capable of spanning up to 91 meters, marking a milestone in modular bridge innovation. With a complete production line for Bailey bridge components and an annual output exceeding 10,000 tons, Great Wall delivers world-class solutions for infrastructure projects, disaster recovery, and temporary military or civilian applications.
The Industry Outlook: Strong Growth and Modern Infrastructure Needs
The global demand for modular and prefabricated bridge systems has been increasing rapidly. Nations are investing heavily in transportation networks, rural connectivity, and emergency infrastructure — all areas where modular Bailey bridges demonstrate their unique advantages.
1. Growing Infrastructure Investment Worldwide
As developing regions continue to expand their road and bridge networks, cost-effective modular bridge systems are becoming a preferred choice. Bailey bridges, known for their quick installation, portability, and durability, are particularly favored for projects requiring temporary or semi-permanent solutions.
2. Critical Role in Disaster Recovery and Military Operations
Bailey bridges play an essential role in emergency response operations, allowing authorities to restore access in disaster-stricken areas swiftly. Their modular structure enables assembly with minimal heavy equipment, making them vital for flood recovery, military logistics, and temporary detour projects.
3. Focus on Efficiency and Sustainability
Modern bridge engineering emphasizes not only functionality but also sustainability. Great Wall’s manufacturing processes use recyclable materials and advanced surface treatments — such as hot-dip galvanizing and zinc-aluminum alloy coating — which enhance corrosion resistance and extend the lifespan of bridge components, reducing maintenance and environmental impact.
4. Advancements in Modular Bridge Technology
Continuous improvements in design, materials, and production technology have made modular bridges more efficient, stronger, and easier to deploy. Companies like Great Wall are at the forefront of this transformation, driving innovation through research and development while maintaining affordability and international quality compliance.
