I found that my Designer home (built 2004) has a mix of wood and metal studs. For the metal studs, I used
"Toggler" SNAPTOGGLE heavy-duty toggle bolts. They are rated as having a
tensile strength of 265 lb. in 1/2" drywall. I used ~30 Togglers to install ClosetMaid vertical shelving brackets. Also used 2 Togglers to put up a massive 53 pound, 63" x 43" antique mirror. It took a bit of engineering to devise the appropriate hardware to use for hanging the mirror. Very happy with performance. Installation is not difficult, but more involved than driving in wood screws. I have 8 left over, if anyone wants them.
