The Folded Steel Plate Girder, or FSPG™
Is an economical alternative for simple and short span bridge construction. This innovative yet simple model has a long service life, requires little maintenance, and is designed for accelerated project delivery.
FSPG™ bridges utilize cold-bent steel plates to form an innovative girder shape that provides strength with lighter weight. Concrete deck panels are precast and attached to the girders to form composite units that can be shipped and erected easily and quickly. High-strength concrete closure pours connect the deck panels to complete the superstructure system.
