Gypsum board and steel structure connection with what
A little bit of the use of self-tapping nails.
Decoration is it! First with a layer of primer, so that after the fixed gypsum board on the line, this seems to be unable to take it
I have not seen such a connection
If it is gypsum board will take some simple fixed measures
You mean steel structure decoration, gypsum board fixed on the keel, keel fixed in the steel structure, I suggest you use light steel keel.
