When building partition walls or installation walls from plasterboard, we must remember about this, that vertical elements – bars, made of C-type sheet metal profiles, inserted into U-profiles should not be permanently connected. U-profiles are anchored to the floor and ceiling. Only retracts the posts. The whole thing is only stiffened by screwed plasterboards. To prevent the posts from shifting or wobbling during installation, it is worth gluing them to the regular U-profiles, wide sticky tape.
