When does it make sense to use metal framing for an interior wall? What are the advantages to traditional wood framing?
Around here they are generally only used in commercial construction or in buildings where flamable building materials like wood are not allowed. Wood is just much easier to work with generally.
Some advantages of metal over wood:
- They don't burn.
- They are always straight.
- Easier to run electrical through (come with holes, so no drilling needed).
And wood over metal:
- Easier to work with (cut, shape, toe nail, etc).
- Stronger. You can't use metal studs for load bearing walls.
- While metal is generally cheaper than wood, the extra accessories needed (special boxes, conduit, etc) can make it more expensive.
- Wood is generally easier to get - most of the big home shops don't carry steel studs.
In my area metal studs are not cheaper than wood studs, but still widely used by pros. That leads me to think that there must be a big time savings with metal once you're experienced. In a large installation the consistency of metal makes follow-on work like electrical and drywall go much faster.
I only used metal once, and found that it was slower than wood for a DIY guy like me. I can pick-and-choose my studs so there isn't a drywall issue for the small jobs I do.
In short, if you're finishing your basement or adding a wall in a remodel, I'd stick with wood. If you're framing an entire house metal might be worth the investment in tools and learning.
