Extending steel studs, how?

[stanlund2]

We are going to build a ceiling where the length is over 3m. How do I best join the steel studs (70mm wide)? Overlap, screw, pop rivet?

 

[Stefan1972]

optional but you'll probably hang them on something above with some nail tape or something.

Nail band as well, of course. How do I attach it to the ceiling, by the way, so that the batten is completely horizontal?

 

[Stefan1972]

there is a gadget called a spirit level..........a slightly more expensive solution is some form of laser level.

 

[stanlund2]

I mean how do you bend the steel band - should it go around the rule?

What type of ceiling will it be? Gypsum board? Spontaneously it feels difficult to screw a board onto a suspended metal stud. Is it a hat profile? Why not wood?

One uses so-called secondary rails on 30cc or 40cc depending on the panel type (900 or 1200), on top of that—depending on how large the room is—one uses primary rails on 1200cc.

For these, there are specially adapted clips to hold everything together, the clips can be screwed into the primary.
Patent band around the primary at suitable places and attached to the ceiling.


The clips are marketed by Lindab but are sold here and there, I have a box in some good place... Indeed, it works just as well to screw the secondary and primary together with blåpär, grispittar, or whatever you want to call machine screws.

And last I checked, the secondary rails came in 3800 length, at least from my supplier. But if you still need to splice, put them inside each other and screw or pop-rivet them together, make sure to support near the splice with a primary.

Around the walls, L-profiles or 45 or 70 Utlägg.
