Can metal studs be load bearing?
Similarly, how much weight can metal studs support?
The axial load, or load weight limit, for metal studs varies widely. An 8-foot, 3-1/2-inch metal stud, for instance, may support over 2,000 pounds, while a 16-foot stud of the same width will support as little as 400 pounds.
Moreover, can you use metal studs in residential?
The only material you CANNOT use on steel studs is traditional nails. There is no way you can hammer into a steel structure with a nail. Only wood is puncturable. You can use a drywall screw for metal studs to make up for the lack of nails available.
Metal studs aren't very wide (typically about 1.25″). Since you will be drilling a 1/2″ hole in the stud, that only leaves about 3/8″ of metal on either side of the whole. And if you've ever tried to drill into the edge of metal, you know that it's impossible without a drill press.
