what i got is a 50'long warehouse with about a 20'high ceiling and 18'wide. both ends have huge roll up doors. im going to make the front end in to a little store. so what i want to do is this...
strap both side walls with 2x4 and a wall across to make the back of the storeand drywall. i only wanted to make walls about 9' high and put a tbar ceiling in at 8'. now being that my original ceiling is like 20' can i hang my tbar from that or am i better off to put some kind of truss on top of my wall. and would 2x4 by enough of a truss remembering that are span is min 16'. thanks for any imput
