Mezzanine Systems

The standard Steel mezzanine framing system consists of a steel deck supported by joists framed onto main mezzanine beams. If required by design loads, the main beams shall also be supported by intermediate columns. The top flange of the joists fits immediately below the top flange of the primary beams. The economy of a mezzanine systems is affected by the applied loads (dead, live and collateral) and mezzanine column spacing. Wherever possible, the primary mezzanine beams should run across the width of the building and be located under the main frame rafters. Joints should run parallel to the roof purlins along the length of the building.
