The next generation of filled grid decks is represented by IDSI's weldless Concrete Overlayed Steel Decks (COS Decks). Our COS Decks offer two primary advantages over standard filled grid decking. First, by placing the concrete slab above the neutral axis of the steel, our COS Decks maximize the strengths of both steel and concrete. Second, our revolutionary weldless design eliminates the fatigue and distortions associated with welding, thus increasing the deck system's life.
Our COS Decks have been tested to more than 14 million cycles without fatigue failure of the steel members. Please click on the links below to download technical specification sheets for each of our COS Deck systems.
