I am trying to mount a TV that's about 20lbs into some studs in the wall. I used a stud finder and drilled some holes where the studs should be but never hit any wood, instead I hit a metal plate about half a centimeter thick.
First off I am puzzled why I would have this metal plate to begin with but I am more concerned by the fact that I can't find any studs. Is this "ok"? Can I safely mount my TV by drilling into this metal plate?
The room in question is in the basement and has finished drywall on the walls. I tried drilling 16in from the corner of 2 walls and tried the stud finder in several locations but everytime I only hit the metal sheet. Where a stud shouldn't be (according to the stud finder), there's no metal plate which makes me think it's a substitute for studs.
If I left out any important details please let me know. Thanks!
