Description
Delta Modular Steel Bridge are new kinds of assembly steel bridges, comprising longitudinal trusses that are formed of steel beam chords and pre-fabricated modular steel panel webs, connected end to end with transverse cross girders spanning between them that support a two lane or a single lane, steel deck roadway or concrete roadway.
The surface protection can be paint or hot-dip galvanized.
Its panel chord is bigger than bailey bridge panel but the panel structure is simpler. All the components are bolted so the bridge can be used as a permanent bridge because of its small deflection.The components are interchangeable and repetitively used.This kind of bridge has various structure changes to satisfy different loading capacity.

Delta Modular Steel Bridge has been widely used in rescue and disaster relief, traffic engineering, municipal water conservancy engineering, dangerous bridge reinforcement, etc. in addition to being a war-ready steel bridge.
Sustainability: Modular steel bridges offer sustainability benefits. Theefficient use of materials, reduced construction time, and potential for reuseor relocation contribute to minimizing environmental impacts. Additionally,steel is a highly recyclable material, allowing for the potential recycling ofcomponents at the end of their lifespan.
Minimal Site Disruption: Modular steelbridges minimize disruption to the construction site and surrounding areas. Thesite preparation and assembly processes are typically less invasive compared totraditional bridge construction methods.
Simple structure
Strong adaptability
Good interchangeability
Longer span
Cost saving
Wider application
Delta Modular Steel Bridge is similar to the panel bailey bridgefrom their appearance. The difference is its increased truss panel height andtruss panel section is larger to afford more loading. Pre-arch method is usedto additionally cut down mid-span and vertical deflection to a larger degree.
The components are connected by connecting plates and fixed with high-strengthbolts. Modualr steel bridges has all the advantages of Bailey bridge, and witha larger span and stronger load-bearing capacity.
Pedestrian and Bicycle Bridges: Modular steel bridges arecommonly used for pedestrian and bicycle crossings. They can be designed withappropriate width, ramps, and handrails to ensure safety and accessibility forpedestrians and cyclists.
