The issue is a timely one ...
At the Home Inspector forums, they're asserting that such 'light steel framing' MUST be bonded, and tell all manner of tales.
I agree that the NEC does NOT require such to be bonded. To me, ?structural steel' has a red primer and is at least 1/4" thick.
My experience has shown this type of framing to be something used only in commercial settings - where, oddly enough, practice has been to not use NM or plastic boxes.
Otherwise, as with suspended ceilings, I've always doubted it was possible to make one without it somehow being bonded.
On balance, I suppose it'snot such a bad idea to have some manner of bonding; I just don't want someone to go overboard, and require listed bonding jumpers all over the place! The last thing wer need is someone worrying about 'sheet metal screws being used ... to connect sheet metal!
