I've been trying to mount a TV on my wall, and have encoutnered a problem locating and drilling into studs.
I used a stud detector to look for studs in my wall, and proceeded to drill.
Instead, I have just hit a metal plate. I did some searching and reading, and it does not appear that the metal is a metal stud. I say this, because I can drill above or below where I hit the metal, and hit nothing. If I drill to the side I also hit nothing. The metal objects seem to be 16" apart.
Whatever the material is, is very tough. I was reasonably certain it was not a protective plate, so so applied some pressure to drill through, but was unable to even get close. I can see where I drilled on to the metal, and it barely left a scratch.
I don't have the experience to cut open and replace a section of my drywall, and so would prefer to avoid that if possible.
I've attached a photo of my wall. I tried to get FiOS installed which was a problem because of the metal I have in my walls, although the technician was not more specific.
What would this metal be that I can drill above, below and to either side of it?
edit: not sure if relevant, but the entire door frame and door are metal also.
edit2: the metal does not go in a straight line from top to bottom, but is rather on a diagonal slant. There is no wood to be found anywhere surrounding the metal.
edit3: I managed to take a picture inside the wall, by putting a phone through the hole to feed speakerwire. It looks like something is bolted in..not sure if this helps to identify what is there though.
