A Bailey bridge is a prefabricated steel truss bridge that arrives in parts and is assembled on site. We supply complete bridges and the parts to build or extend one: panels, transoms, braces, decking, end posts, bearings, pins and bolts. Spans run from 9 m to 61 m depending on the configuration and the load it has to carry.
- Footbridges and pedestrian crossings
- Highway and access bridges
- Bridges over water and drainage channels
- Railway and construction site bridges
- Viaducts and temporary crossings
- Emergency access after floods or earthquake damage
Everything connects with pins and bolts — no site welding, no heavy plant. Panels are pinned together in rows, transoms carry the deck, and sway and diagonal braces stiffen the assembly. The bridge can be assembled on rollers at one bank and pushed across, or lifted into place by crane. It can also be dismantled and reused at another site.
- Bailey panel: 176 × 2234 × 3163 mm, 306 kg, Q355B. High anti-shearing panel: 354 kg
- Reinforced chord: 100 × 176 × 3163 mm, 86.2 kg, Q355B
- Bailey pin: Φ55 × 195 mm, 3 kg, 30CrMnTi
- Transoms: 5.8 m, 6.2 m and 9.57 m, up to 885 kg
- Sway braces, support panels (horizontal and vertical), diagonal braces and connecting plates
- Bridge decking, clearance plates, end posts (concave and convex), bridge seats and seat plates
- Bolts: M24 and M30, grade 8.8
Configurations are named by rows and storeys: SS (single-single), DS (double-single), TS (triple-single), DD (double-double) and TD, with an "R" suffix for the reinforced version.
| Span Range | Configuration | Load Capacity |
|---|---|---|
| 9-12 m | SS to DS | Auto-10 to auto-20; DS for 80 t trailer |
| 15-24 m | SS to DSR | Light vehicles to crawler and trailer loads |
| 27-36 m | DSR to TSR | Middle range to top capacity |
| 39-45 m | TSR to TDR | Depending on vehicle type |
| 48-61 m | DDR to TDR | Heavy duty configurations |
Send the span, vehicle types and axle loads and we confirm the configuration rather than leaving you to read a table.
- Bridge parts: Q355B and Q235B structural steel, 30CrMnTi pins, grade 8.8 bolts
- Plates and flat bar: ASTM A36 or A572 Grade 50, or EN 10025 S275JR / S355JR
- Common size: 10 × 2000 × 8000 mm
- Weight calculated at 7.85 g/cm³ for freight and customs planning
Hot-dip galvanizing is standard for bridges — inside and out — so the steel survives weather, water and road salt. Painted finishes are available where appearance matters.
We support the whole job, not just supply: design, production, construction and maintenance. Assembly guidance is given remotely by video call, or by sending an engineer to site if you prefer. After-sales covers maintenance and dismantling.
- Span — clear span, and whether intermediate supports are possible
- Roadway width — single lane, two lanes or footbridge
- Load — vehicle types and axle loads, or pedestrian loading
- Site — over water, over a road, temporary or permanent
- Steel standard and finish — galvanized or painted; ASTM or EN plate where required
- Deck — steel deck or timber deck
Design work is free.
Fabrication and galvanizing are done before shipment, with packaging to suit sea freight and onward road transport. Parts are packed by type so the assembly sequence is not held up at site. Lead time is confirmed against the span and quantity when you order.
