Standard mezzanine floor system consists of galvanized steel decking/checking plate supported by joists framed onto main mezzanine beams. The main beams shall be supported by intermediate columns when required by design loads. The primary mezzanine beams normally run across the width of the building and the joists normally run lengthwise (parallel to the roof purlins). The economy of a mezzanine system depends on applied loads (dead, live and collateral) and mezzanine column spacing. Multi level mezzanines, interior equipment platforms, catwalks and staircase can be accommodated if required as per complete given design data.
