Q345B Pre-engineered Modular Steel Bailey Bridge Heavy Capacity Long Fatigue Lifespan


In 1938, British engineer Donald West Bailey invented the Bailey Bridge. This bridge is made of high-strength steel and is made of lightweight and standardized truss elements and beams, longitudinal beams, bridge decks, bridges and connectors. The composition can be quickly assembled into a truss girder bridge suitable for various spans and loads with special installation equipment. It is named as a fabricated highway steel bridge in China, which is one of the steel bridges, but it is not equivalent to steel. The bridge and the Bailey Bridge are more typical. The main feature is modularity, and the application is more convenient and extensive.

AdvantagesPrice effective and technical full analysis and supports


Spans from 3.6m to 31m and more - for highways, railways, pathways, bicycle racks, landscaping, etc

Standardized designs - as per Indian BIS a. RC standards and codes

Heavy live loads with high overfills - capable of supporting heavy freighter aircraft and mining haulers

Smooth approaches - from earth embankments due to soil overfill, does not require any approach slab

Low life cycle costs - traffic runs on overfill and not over an exposed bridge deck

Aesthetic structures - the true arch form is accentuated.


Bailey Bridge can form temporary bridges of various types and uses according to the different needs and spans of the site. Therefore, the Bailey frame has the characteristics of simple structure, convenient transportation, fast erection, easy decomposition, less construction, low cost and light weight. Moreover, the beret also has the characteristics of large carrying capacity, strong steel structure and long service life.

Stress characteristics
(1) The piers and columns are rigidly connected, and the beams are unloaded due to the bending resistance of the piers. The whole system is a compression-bending structure and also has a thrust structure.
(2) The clearance under the bridge of the steel truss bridge is larger than that of the arch bridge, and a smaller span can be constructed under the same clearance requirements.
(3) The construction of steel truss bridges is more complicated, and is generally used for overpass bridges and overpasses in cities or highways with small spans.
(4) Steel truss bridges constructed with prestressed concrete and cantilever construction have become one of the competition schemes for long-span bridges.

Our company

Our experienced team is focused on your steel bridge project's success, from start to finish. Our proven ability to identify and overcome design inconsistencies, potential problems with erection, and shipping obstacles results in the fabrication of structural steel that is right the first time, helping you avoid costly construction delays.

Proper project coordination and efficient delivery of the structural steel to your bridge project is a key factor in its ultimate success. This is what gives us the leading edge.

From material purchase and tracing, planning compilation, drawing detailing, production arrangement, quality inspection, to on-going painting, packing and delivering, we have separated department to strictly control process, quality and traceability, so that the perfect Bailey/Belay/Baley Bridge can be made.

Finally we would like to emphasize that not like other companies, nearly all machining parts and mechanical accessories are manufactured in our own shop as we have so many wonderful machines and workers inside. In this way, the quality, cost and delivery time can be ensured which eliminates other exterior factors’ influence.
