My house has metal stud-framed walls. I've ripped out the existing (steel) interior door jambs because they were ugly and busted. But I'm unsure of how to go about installing new prehung doors. I've heard that attaching a wood door jamb to the metal studs won't work because the screws into the steel studs will strip out, and that the solution is to line the rough opening with wood blocking (plywood perhaps). But doesn't this just replicate the problem? The blocking, just like the door jamb, has to be secured to the metal somehow.
Note that, because this isn't a new build, I can't come at the blocking from inside the wall (thus anchoring the screw head against the steel) without tearing up the drywall.
So what can I do? Just screw a wood jamb into the steel and cross my fingers? Rip out the rough opening and install a wood frame? Install a metal door jamb?
