I recently removed the drywall ceiling from my basement with the intention to leave it as an exposed ceiling. Would I be correct in understanding that the metal ceiling joists (highlighted in blue in the pictures) are for drywall support only, and not structural? I believe that the iron girders are the structural support. Would like to remove the metal joists for more space.
To be more accurate, it would appear that these are metal furring channels, not joists.
The blue highlighted joists are the ones I am hoping to remove.
