First Edition CJ-Series Standard Specifications for Composite Steel Joists, Weight Tables and Bridging Tables, Code of Standard Practice PDF

CJ-Series Composite Steel Joists are an excellent choice for floor framing. The open web steel joists can span long distances to create wide-open spaces. At the same time, they offer an excellent span-to-weight ratio, which decreases the overall weight and cost of the steel structure. A maximum span-to-depth ratio of 30 is greater than the typical roof joist span-to-depth ratio of 24 and allows for even shallower joists to achieve the wide column spacing. The open web construction of the joists allows MEP trades to run plumbing, electrical, and mechanical equipment through the joists rather than under the beams. This minimizes the overall floor depth, maximizing ceiling heights, and/or reducing the overall building height.
