Girder bridges are a basic type of bridge that uses girders to support the deck. The deck is the roadway or pedestrian path that sits on top of the girders.A girder bridge has three parts: 

  • Foundation: Consists of abutments and piers
  • Superstructure: Consists of a girder, truss, or arch
  • Deck: Located at the top of the girder

Girders are horizontal beams that span between two abutments or piers. They carry the weight of the bridge deck. Girders often have an I-beam cross section, but may also have a box shape, Z shape, or other forms.

The two most common types of modern steel girder bridges are plate and box. Box girders are used for highway bridges, railway bridges, and footbridges.

Innovations in Design:

NPEC stands at the forefront of innovation in Plate Girder Bridge design. Our company consistently explores new materials and construction techniques to enhance the performance and longevity of its bridges.
