Fxing to metal studwork

[JoinerMike]

Hi all
Long story short. Friend got someone to divide 1 room into 2 and he did it with metal studwork. It's all done and plastered. She now wants me to fit a couple of door casings and doors. I have never worked with metal studwork.
What is the best way to fix the wooden 4" door casing to the metal? What fixing do I need?
Thanks all

havnt done much with this stuff either,but would think you have to find 1 upright and try and work from there,maybe even build a sub frame within the metal studs to take the door linings???

Thanks for your reply
The uprights are there, they have done it properly. It has a metal lining in the opening. Guessing that there only thin pieces of metal so will need some sort of self tapping screws, but same as you never used it once.
Don't want to fit the casings & doors only to find them popping out when the kids slam their door in a tantrum

Beef up the stud with a bit of CLS.

How can I get the CLS in without destroying the plastered walls?

Gyprock screws go into this stuff without drilling, I'm not a great fan of this stuff but I guess that's a starting point, short of doing major take down,My instinctive feeling would be to foam the the frame in just for insurance always assuming that the rest of the stud is strong enough to take it

Casings should have gone in before plasterboard was applied so the metal work was screwed to the timber rather than the timber to the metal.Only option now is as HWW suggests.

Avoid over tightening or they will rip the metal work.

Thanks all
Not measured the opening yet but if there is room I will put some packers in and get some foam behind to try and secure it a but more.
Cheers all, thanks for the advice, i'll pick some of them screws up.
Why are even the simple jobs never bloody simple lol

I helped build a Gyproc metal studwork in a church some years ago. Bloody great 6" wide stuff. We were blocking off one end and this had a double door built into the framework. As others have said, the frame was fixed into position,(screwed from behind and through the metalwork) before the plasterboard was screwed on to the studwork.
I have used the smaller stuff before, but only on council house refurbs where the studwork was placed against all external walls and insulated, before covering with the plasterboard.
