Steel Box Girder Bridge refers to a beam bridge whose main beam is in the form of a thin-wall closed section. Long hollow trusses made of steel or concrete are usually used as beams. This makes the bridge light and sturdy. Bridges constructed using this method are called Steel Box Girder Bridge.

Steel box girder bridges are commonly used for highway flyovers and for modern elevated structures of light rail transport. Although normally the steel box girder bridge is a form of beam bridge, box girders may also be used on cable-stayed bridges and other forms.
Parts of the bridge
The basic Bailey bridge is made up of three main parts, the floor, the stringers and the side panels. The floor of the bridge is made up of a number of 19-foot-wide transoms (5.8 m) that run across the bridge. Across the bottom of these, forming a square, are 10-foot-long stringers (3.0 m). The bridge's strength is provided by the panels on the sides. The panels are 10-foot-long (3.0 m), 5-foot-high (1.5 m), cross-braced rectangles. Each weighs 570 pounds (260 kg), and can be lifted by six men.
Generally used for urban bridges or highway viaducts and overpasses with small spans
Reinforced concrete: medium and small span
Prestressed reinforced concrete: large span
Straight leg frame (door type) and slant leg frame: medium and small span
T-shaped rigid frame, continuous rigid frame: large span

For steel box girders, the girders are normally fabricated off site and lifted into place by crane, with sections connected by bolting or welding. If a composite concrete bridge deck is used, it is often cast in-place using temporary falsework supported by the steel girder.
Either form of bridge may also be installed using the technique of incremental launching. Under this method, gantry cranes are often used to place new segments onto the completed portions of the bridge until the bridge superstructure is completed.

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.
The success of the Bailey bridge was due to the simplicity of the fabrication and assembly of its modular components, combined with the ability to erect and deploy sections with a minimum of assistance from heavy equipment. Many previous designs for military bridges required cranes to lift the pre-assembled bridge and lower it into place. The Bailey parts were made of standard steel alloys, and were simple enough that parts made at a number of different factories could be completely interchangeable. Each individual part could be carried by a small number of men, enabling army engineers to move more easily and more quickly than before, in preparing the way for troops and materiel advancing behind them. Finally, the modular design allowed engineers to build each bridge to be as long and as strong as needed, doubling or tripling up on the supportive side panels, or on the roadbed sections.
