JANSON PLATE GIRDER BRIDGES
Bridge and flyover
Janson's Plate Girder Bridge units ( code JSB ) are designed for temporary or permanent applications particularly in areas of heavy traffic conditions where single spans up to 40 meters for all general traffic are required. Janson's Plate Girder Bridge system has been designed and manufactured for speed of erection. The units are transported to site, lifted into position and bolted together in minimal time. They can be connected laterally (side-by-side) and longitudinally (end-to-end) offering a vast range of free spans and road widths. Multiple spans can be constructed as continuous bridge, simply supported spans or broken spans with span junction equipment.Each unit has a width of 2.5 and 3.5m. By joining the units sideways any required road width can be achieved ( 3.5 – 5.0 – 6.0 – 7.0 – etc. ). The exterior units can be equipped with parapet rails and kerbs or pedestrian fencing. The units are built from steel trusses with integrated steel trough decks which have an integrated antiskid surface consisting of epoxy resin embedded with aggregate.
