Benefits: Structural steel mezzanines allow for a much greater column spacing than any other mezzanine system.  Electrical conduit, water pipes etc. can be easily run through open web bar joists.  Open web bar joist give a much more "open feel" than standard beams, giving the illusion of more clear height.  Structural I-beams can be used to minimize the "deck profile" of the mezzanine.

Drawbacks: Structural steel mezzanines are much heavier than most other systems so will have a higher dead load and a higher floor load.  The increased weight will also increase freight cost from factory.  Structural steel has a rougher finish than any other mezzanine material.
