Since their inception in the early 1930's, concrete filled steel grid decks are unsurpassed in durability and longevity. In fact, there are bridges in the U.S. that have their original filled grid deck systems still in place from the 1930's. It is common to see filled grid deck systems last 50-70 years and, more often than not, find that the filled grid deck outlasts other superstructure components.

The longevity of filled grid deck can be attributed to its fundamental design. In combining the tensile strength of steel with the compressive strength of concrete, filled grid deck utilizes the capabilities of both materials. In addition, filled grid deck is usually substantially lighter than reinforced concrete slabs. As you will find below, filled grid deck systems come in a variety of heights and designs.
