Prefabricated grid reinforced concrete and Exodermic® bridge decks help accelerate bridge construction using either cast-in-place or precast installation. These grid deck systems are also very lightweight and durable, often times weighing 30-50% less than conventional concrete decks and still providing increased life-cycle cost performance when considering they last 2-3 times as long as rebar decks. Open steel grid flooring is the lightest deck system available and is optimal for movable bridges or truss structures where weight savings is a key requirement.
