Exodermic® Bridge Deck System

An Exodermic® (or "composite, unfilled steel grid") bridge deck is comprised of a reinforced concrete slab on top of, and composite with, an unfilled steel grid. This efficient system maximizes the use of the compressive strength of concrete and the tensile strength of steel to provide a lightweight, strong and durable bridge deck.
