I think I know the answer to this (NO!) but buddy who did the wall for me
says that he can insert wood into the metal stud and then lag-bolt the TV
mount to that. I want to believe him but that is why I am here: will a 2
foot length of wood in a metal stud support a 100 pound TV? Where does the
support come from if the wood isn't running ceiling to floor? Etc...
Any thoughts from the group (especially the framers out there!)
I know the truth is out there, but I like to stay in...
You don't just have a metal stud. Presumably, you have a wall with
multiple studs at a standard spacing, covered with sheetrock, etc.
In that case, even without using an additional wood support, the load
is spread out and carried across multiple studs. The studs are also
prevented from deflecting by the support of the sheetrock.
Distributing 100lbs over multiple studs should not be a problem. I'd
make sure whatever bracket is behind the TV is securely screwed to at
least 2 studs.

The real issue is how far out from the wall is the flat screen...if
the bracket picks up two studs & the TV mounts more or less flat to
the wall... a few Tek screws into the studs will do the trick.
If the TV hangs off the wall like ~12" then i'd be more concerned.
The gauge of the studs is also an issue...20 gage ( 22, 24) are
pretty thin & screw pullout is a concern.
Thicker studs; 18 & 16 gage are really very reliable with respect to
If you still have access to the steel framing, your buddy's idea of
putting two wood backers into the steel studs is fine.
The steel studs are very strong vertically but locally (screw pullout
& local bending) then are potentially weak. Putting the wood inside
them will stiffen then up & give the lags something to embed in.
I'm curious as well. I was going to suggest a well-trimmed and finished
3/4 plywood panel applied to the wall with lots of long countersunk
sheetmetal screws, and hang the TV off that.(You could even cut out part
of the rock, use 1/2 ply instead, and flush the wood in to make it
vanish completely.) Make it just shorter than the vertical height of TV,
and as wide you can to go across as many stud bays as possible. About
the same way stuff was hung off old plaster lath walls. But if wall is
open, even on one side, you could put massive blocks in the stud spaces
and stiffen the hell out of the wall.
If it's a house The studs are most likely a light gauge. What I would do I
would add extra studs were you want to mount the T.V. Then solid metal
backing over those studs ( your framer should know how to do this)to catch
the support area for the T.V. Most backing I've seen is 6" wide, but in
some instances they will use a solid piece of sheet (say like 24" wide 4'
long) metal. I have even seen metal studs covered with 3/4" ply for backing
. there's a lot of ways to solve how to hang a flat screen.
The support will still be the metal stud. The wood is just a backer to hold
the lags in place and spread the load over a portion of the stud.
Sheetmetal screws may pull out if just into a thin stud. I just saw doors
being hung by putting in a wood backer where the hinges will be.
