What Are Plate Girders for ROBs?
A plate girder is a large, deep structural beam built by welding or bolting together individual steel plates — used where the span and load requirements exceed what a standard rolled beam can carry. For Road Over Bridges, plate girders form the primary load-bearing structure that supports the road deck above a railway crossing, distributing traffic load across the span and down through the bridge’s piers and foundations.
Because ROB structures carry public traffic directly above active rail lines, plate girder fabrication for this application demands close tolerance welding, verified material grade, and rigorous quality testing before dispatch and erection.
