I am trying to install a bike hoist on my garage ceiling, and ran into this piece of metal when drilling through the drywall to the joist:
It looks like the material behind the metal plate is wood. Can you tell me what this steel is? Can I drill through it to the wooden joist?
Update:
Since this is in first floor garage, with Living room upstairs, it doesn't help to check from the attic.
I dug the hole a little more from both sides, it looks like, and I can feel, that it is the regular 2 by 4 wood stud behind the metal plate, and there seems to have no wire etc I can touch around. So is it safe to drill?
I need to screw with a 3" lag bolt through the metal, so I guess I will need a titanium drill bit to do the work?

I wouldn't drill it. It's probably a truss splice plate. Can you get in the attic and look to see if it wraps up the sides of the bottom chord?
