The HD200 Bailey bridge is our flagship panel bridge: a heavier-duty evolution of the classic Bailey system, engineered for permanent and semi-permanent crossings where standard panels run out of capacity. Deeper panels, higher load classes, longer spans — assembled from the same container-shipped, crane-free erection philosophy.
Why HD200 instead of a standard Bailey panel
| Parameter | HD200 | Standard Bailey / Compact 200 |
|---|---|---|
| Panel depth | 2.14 m (deeper truss) | 1.45 m |
| Typical single span | 30 – 60 m | 15 – 30 m |
| Load capacity | HS25 / Class 75 and mining axles | HS20 / Class 60 |
| Reinforcement | Single, double and triple chord options | Single / double |
| Deck systems | Steel deck, timber-composite, asphalt-ready | Steel / timber |
| Corrosion protection | Hot-dip galvanised to ISO 1461 | Hot-dip galvanised |
Where HD200 earns its price
- Permanent public roads. Deeper truss and stiffer deck keep deflection and driver comfort within road-authority limits for decades, not months.
- Mining haul roads. Re-analysed for your actual axle spacing and gross vehicle weight — not a catalogue class.
- Longer spans without piers. Where a standard Bailey would need an intermediate pier, HD200 crosses clear.
- Rapid redeployment. Bolted panel joints demount cleanly for temporary works that move between sites.
Delivery and erection
HD200 panels, transoms, stringers and decking pack into standard 40 ft containers and are trial-assembled at our Zhenjiang factory before shipment. Erection is by cantilever launch with a nose and rollers — no crane on the far bank, no work in the water. A typical 40 m crossing is erected in 5–10 days by a 25-person crew.
Documentation shipped with the bridge
Mill certificates, WPS/WPQR weld records, galvanising thickness reports, trial assembly report and the project-specific design check (AASHTO or BS 5400 load cases). Third-party inspection can be witnessed at the factory.
