Steel studs against gypsum ceiling, fastening
Hello!
I'm planning to frame an interior wall in the basement using steel studs and tracks. How should I attach the track to the ceiling, which is a gypsum ceiling with double gypsum boards (I believe) that are attached to wooden studs? What screw should I use?

The steel rail should not be attached to the ceiling if you're building an interior wall against the outer walls; it should be attached to the existing wall! If you're dividing a room, you attach the ceiling rail over the studs and drill and fasten with appropriately long wood screws, preferably stainless steel, as they are more flexible and do not break in the same way as ordinary sheet metal screws for wood! You don't need to remove the plasterboard before attaching the ceiling rail, but make sure it's firmly attached to the existing wooden studs! What will you use the room for? It matters somewhat for the construction.
Thanks!
I would like to have a small, small gap between the rails and the outer wall, though maybe it doesn't matter? I've just seen on the forum here that several people place their walls a few mm/cm away from the basement wall so that they have no contact at all.
What kind of screw is suitable for the outer wall, it's lightweight concrete blocks, if I were to attach there instead?
How would you attach the floor rail to the floor, concrete slab. Concrete screw? How long in that case?
There will be no insulation, only plasterboard and OSB board in certain places.

I would probably rather fasten with screws than glue in the floor. Is it concrete screws that are needed then? Is 40 mm enough?
One last question...: In part of the room, I have recently used EPS concrete and poured self-leveling compound on top. How should I fasten the rails to the floor here? Do concrete screws work in self-leveling compound/EPS concrete too? The self-leveling compound is about 20 mm thick, then there is EPS concrete, and then a concrete slab.

Glue is incredibly durable, otherwise you should drill and use nail plugs or drill, use nylon plugs, and stainless steel construction screws. The point with the stainless steel ones is that the screws hold up over time. Many people use the wrong screws because at the hardware store they often say it's fine with combination screws or something else. Nail plugs are better than screws many times, test drill in a couple of places and go with different systems, nail plug, screw, or glue, all three methods work just as well. You drill the nail plug straight through the metal stud and drive it directly into the drilled hole, if something goes wrong it's not the end of the world, the only thing that might happen is you have to buy more and drill a few extra holes! And to your question, no, I think it's wrong to use 40mm concrete screws. There are advantages to them but not for 20mm filler and eps concrete. Better with 100 mm nail plugs.
