Hello everyone.
Our prefabricated garage was installed on Monday. We chose a large steel prefab garage measuring 6 x 9 m (20 x 30 ft) from the company "Garagenrampe." We now want to add a partition wall inside.
I would like to build this using metal studs similar to those used in drywall construction. On these, I would first attach OSB boards, and then either gypsum board (drywall) or cement fiberboard on top.
My question is: Would this be feasible in an unheated garage where there is some moisture present? Is it possible to use OSB boards, for example? And is it really necessary to use cement fiberboard, or would impregnated gypsum boards be sufficient?
My main concern is mold growth.
Thank you very much in advance.

that my wife wouldn’t like a plain OSB wall visually.In a steel garage, you care about the appearance?Otherwise, I would just paint it white or gray and be sure to install the electrical wiring at the same time.
With thin metal walls, you always have to come up with a solution for how to install outlets and switches.

I think there are different profiles for steel garages. Maybe you have different ones than the original poster and me. (take a look at the pictures)
Gluing might work for light switches. For sockets, the forces from pulling and pushing would be too strong for me.
I cut a piece of OSB board to fit, glued it into the steel profile, and as a precaution, screwed it in from the side, then mounted the sockets and switches on it.

I cut a piece of OSB board to size, glued it into the steel profile, securely screwed it on the side just to be safe, and mounted the sockets and switches on it.You can screw it onto the vertical intermediate profiles. Or the screws will stick out if it’s on a hidden side. And these days there are such great adhesives that nothing will come off.
