I have a situation where i am helping a friend hang a 50" plasma t.v. in his waiting area(lawyers office).The wall that he wants to put it on is made of those sheetmetal 2x4's and 1/2" drywall.The t.v weighs 110lbs and the bracket weighs about 30 lbs.what is the best way to anchor this.i was thinking of hitting 2 studs with lags then use large toggles on the other holes,but since this weighs so much i am skeptical? any ideas would be greatly appreciated.

Re: HANGING A 50" PLASMA
you would be surprised how much weight drywall on metal studs can hold.

Re: HANGING A 50" PLASMA
The last bracket I did saw installed was adjustable, and required a wall capable of supporting 400 lbs. It all has to do with the moment created by the weight (i.e. how far out away from the wall is the weight, and how far apart are the mounting holes?).
Other variables are how tall the wall is, and what gauge the studs are. I would at least let your friend know you aren't liable for damage to the TV if the unthinkable happens.

1/4" toggles through the studs. Possibly putting up a stick of strut, grabbing several studs, should work.
Goodluck

Re: HANGING A 50" PLASMA
It depends on how far out the monitor is and how far apart the screws are as Steve says.
I tend to be very nervous of these type of things. Manufacturers often have little idea about physics and only care about the looks. I certainly would not want to be responsible if that thing comes down.
My best advice is to use your head and your gut feeling. Steel studs, particularly the light gauge ones most often used offer little pull-out resistance compared to wood. With anchors in the sheetrock you are at the mercy of the pull out resistance (not SHEAR).
If I were in your shoes I would remove an area of sheetrock, install some large wood blocking attached to the studs then replace the sheetrock. This can be done from the other side of the wall if it makes it any easier.
If the lawyer doesn't like it walk away. Obviously he has the money, make sure he doesn't get yours someday.

Show him that you are smart too. Suggest a floor stand.

I was just thinking: If you asked this question on a professional carpenters forum, wouldn't you be accused of being a DIYer? In which case their response might be - Hire a professional.

110 lbs across two studs in a finished wall is no big deal.
)
Locate the studs use a 5/8" or 3/4" hole saw to make the holes and stick in some 1/4" toggles.

I was thinking the same thing, that is how I hang large panels on these walls and I can stand on the panel when I am done. (I am a bit over 110 lbs.

Re: HANGING A 50" PLASMA
Locating the metal studs and using toggles as the anchor with washers would seem to be okay.
"(I am a bit over 110 lbs. )"
Ya - which leg?
Just kidding Bob, I could not resist.

metal studs with drywall hung are A LOT stronger then you might think. 110lbs should be any problem at all. even with the thin gauge steel

I think the toggles in the metal studs would be better than the lags.

As many have said, the toggle bolts would hold that load, but if that don't work for you, get some marine grade plywood, cut it to size, toggle bolt it to the drywall, but first put some liquid nails on it. Now use wood anchors for your tv stand, or toggle thru the wood and the drywall. Now you can hang a fat momma up there on top of the lawyers tv set also.

YUCK!
Then there was the time I was wondering what the hell I was doing, when I had to pull a raw sewage pump on a Saturday so that they could upen back up their restrooms during a huge Pacific N.W. Tribal event. I ended up finishing up the job without a shirt, for the obvious reason cus the pump drained all over it.Originally posted by davedottcom:
