Bailey Bridge, also known as prefabricated steel truss bridge, is a classic standardized modular prefabricated steel structure bridge. Originating from emergency engineering erection scenarios, it is the most widely used temporary traffic bridge solution worldwide. Assembled from universal standardized Bailey panel units with a mature structural system and excellent interchangeability, the bridge can flexibly adopt single-layer, double-layer, single-row and multi-row structures according to span and load requirements without complex customization. Complying with national 321 prefabricated steel bridge standards and international engineering specifications, it features outstanding flexibility and structural safety, meeting both temporary construction passage and short-term permanent passage needs, and is widely used in infrastructure construction, emergency disaster relief, traffic diversion, mines and factory areas.
The core load-bearing components including Bailey panels, trusses, supports and pin shafts are forged and processed from Q345B low-alloy high-strength steel, which features high strength, good toughness and strong impact resistance with stable load performance for repeated passage of heavy-duty vehicles. All components are factory prefabricated with standardized precision processing and non-destructive flaw detection, featuring unified dimensions and strong adaptability. All series of components are universally interchangeable with no customization threshold. The surface adopts multiple anti-corrosion processes including hot-dip galvanizing, epoxy anti-corrosion spraying and anti-rust primer, which effectively resists outdoor corrosion from sunlight, rain, humidity and construction dust, greatly extending the service life and adapting to complex working conditions such as field sites, construction sites, waterside and high-humidity environments. Complete matching connectors, supports and bridge decks ensure tight assembly, balanced stress and highly controllable installation accuracy and finished product quality.
