chalkboard studs....

[boaby]

hi all,

my flat has mostly chalkboard walls and im attempting to fix a metal plate (lcd mount) up in the living room. borrowing one of those cavity sensors i located my studs and marked out all my points of interest.

anyhoo, i poked the first hole through the chalkboard and set about pre-drilling a hole for a woodscrew. after about ten seconds of the drill bit just spinning, i cleared the hole in the gyprock and was quite surprised to see metal where i was expecting to see wood. i assumed the joists would all be wood (not sure why).

now im a little confused. without me ruining my walls further/needlessly can anyone tell me....

- are my joists like metal I-beams or something?, OR
- are they definately wood with a metal cover?


any help/advice would be appreciated here.

How old is the property?

Probably metal stud walls, if its an internal wall.

I didnt even know metal studs were even in use. Looks like your right, i only now noticed the cavity sensor also has a metal-sensing facility and it seems to confirm all metal studs.
