Re: Steel framing
All I can tell you from a commercial/hospital point of view is:
1. They don't burn for a fire, but if heated enough they will lose their structural integrity and bend/twist (think of 911).
2. They are great for WDO problems.
3. I have heard from installers that they can go faster (vs lumber construction) if done by a competent/experienced crew.
4. They can be ordered in different gages/thickness for whatever the structural application is.
5. They can be ordered in different lenghts for balloon framing.
6. They come pre-punched for electrical, plumbing pipes to go through.
