CB100(CB321)Bailey Bridge
BAILEY
The Q321 Bailey Bridge (Model ZB200-321) is a high-strength prefabricated steel bridge engineered for rapid deployment and heavy load-bearing. Manufactured from premium Q355B to Q460C steel, it strictly adheres to ASTM and GB standards. Ideal for pedestrian walkways, highway bypasses, and emergency construction, this bridge features a versatile modular design certified by ISO9001 and authenticated by military-grade research institutes for unmatched reliability.
As a premier prefabricated steel bridging solution, the Bailey Bridge offers exceptional versatility and strength. With over 18 years of manufacturing expertise, our modular system allows for single or multiple-layer configurations (SS, DS, TSR, DDR) to meet specific load requirements, ensuring rapid installation and long-term durability in various infrastructure projects.

Military-Grade Certification: All components are tested and authenticated by the No.2 Engineer Research Institute of the Chinese People’s Liberation Army, ensuring top-tier structural integrity.
High-Strength Materials: Utilizes Q355B-Q460C high-performance steel, providing excellent load-bearing capacity and longevity.
Rapid Installation: The modular "Bailey" design allows for quick assembly with minimal equipment and labor, significantly reducing on-site construction time.
Versatile Configurations: Offers multiple truss combinations (Single/Double/Triple row, Reinforced/Non-reinforced) to meet varying span and load requirements, from pedestrian bridges to heavy highway loading (HS25 & HA standards).
Comprehensive Quality Assurance: ISO9001:2015 certified with a strict 12-step manufacturing process—from sawing and welding to surface treatment and painting—ensuring consistent quality.
Highway & Bypass Construction: Ideal for temporary road diversions and permanent crossings where rapid deployment is needed to maintain traffic flow.
Pedestrian Walkways: Perfect for urban landscaping, parks, and pedestrian overpasses requiring aesthetic integration and safety.
Emergency & Disaster Relief: Designed for rapid deployment in disaster-stricken areas to restore critical transportation links quickly.
Hydropower & Industrial Projects: Successfully implemented in projects like the Sichuan Niangyong Hydropower Station and Lhasa Bangduo Hydropower Station for heavy equipment access.
International Infrastructure: Extensively used in global projects across the Philippines, Nepal, Bangladesh, Indonesia, and Africa, adapting to diverse geographical and climatic conditions.

Engineering Support: Dedicated engineers keep in touch to understand your exact requirements.
On-Site Guidance: Our engineers explain product use and provide necessary service during installation.
Inspection: Thorough inspection of bridge products to solve any arising issues.
Feedback & Follow-up: Service information is fed back to our center; we follow up via online platform to ensure satisfaction.
Q1: What is the maximum span length achievable with the Q321 Bailey Bridge without intermediate supports?
*A: The maximum span varies by configuration. For single-lane loading, the reinforced double-layer truss (DDR) can achieve spans up to 60-70 meters, while the triple-layer reinforced (TSR) configuration can extend beyond 80 meters depending on load requirements.*
Q2: Can the bridge be customized for non-standard widths or special loading requirements?
*A: Yes, we offer customization. In addition to standard single-lane (4.2m) and double-lane (7.35m) widths, we can adapt the deck system and truss spacing to meet specific project load classes, including HS25 (US) and HA (UK) standards.*
Q3: What is the difference between "reinforced" and "non-reinforced" truss configurations?
A: Reinforced models feature additional chord reinforcement at the top and bottom of the truss, significantly increasing the moment capacity (e.g., SSR offers 1687.5 kN.m vs SS at 788.2 kN.m) without changing the overall structure height, making them ideal for longer spans or heavier loads.
Q4: What surface treatment do you apply to ensure corrosion resistance?
*A: Our standard process includes shot blasting (Sa2.5 grade) followed by zinc-rich epoxy primer and polyurethane topcoat. For marine or highly corrosive environments, we recommend hot-dip galvanization as an optional treatment.*
