hah, got your attention….
got a job to relocate a 6’0″ double leaf fire rated door from in a block & furred out rock wall into a new alcove, so the doors don’t swing out into the corridor
floor to deck abpve is ~14′
ignoring for the moment (pretend you’re an architect here) the mass of pipes, conduit & ductwork above the accoustic ceiling, what gauge steel stud would you use to frame the new alcove?
prints show two studs set channel to channel at the door buck, no guage sepecified
what’s the heaviest guage you can use & still use tappits to srew it together?
thanks all you studs!

You could use structural steel studs and still be able to screw it, but 16 gauge is more than enough.
Depending on your field conditions you might want to put a stongback above ceiling hieght and/or a couple of diagonal braces. The weight of most fire rated doors and the amount of use they'll see will dictate if that's needed.... Buic
Thanks....I was leaning toward 18 or 20 guage...as far as strongbacks, I'll be lucky to get 60% of my ceiling track up in one uncut section, so some bracing will surely be in order....
