The unique design of a UNIBRIDGE® steel bridge structure means that a reliable, robust, sturdy bridge, meeting local rules and regulations, can be constructed without having to design a new structure for each situation.
UNIBRIDGE® steel bridges are based on a modular system, which uses a limited number of parts to build individual modules. The modules are then joined together lengthwise up to a length of 45m and laterally to have one, two, three or more lanes of traffic in a road application.
All the elements of a UNIBRIDGE® steel bridges can be transported to the site on a normal semi trailer in the case of 11.6m modules or on a rigid two axle truck with a 6m module.
To add the flexibility of UNIBRIDGE® steel bridges, both module lengths can be used together to create bridges of 18m (54ft), 24m (72ft), 30m (90ft), 36m (108ft), 42m (12 ft) and 48m (144ft) between abutments.
UNIBRIDGE®’s steel bridges revolutionary design means that you can construct a “customised” bridge from pre-fabricated modules to suit the application and local conditions.
One key feature of UNIBRIDGE® steel bridges is the ability to pre-camber the beam elements to suit the span lengths of the bridge. The only span lengths that are not pre-cambered are the single beams of 11.6m and 6m spans.
