That weakens the construction quite a bit! A metal construction doesn't forget stresses!

Huh. You know some builders in my town thinking like you. You know what happened with them? They are in jail now. They took off ceiling general support pylons and wood covering little bit overstressed and broken down. 3 peoples was killed. Is ceiling has a metal rails covering 3 peoples doesn't die. Its only sagging, but not breaking. That is wood and metal constructions difference. Wood is wood, metal is metal. Thats not important where are you used it.
