Metal studs are standard for commercial framing from structural 10 or 12 gauge material to 20 gauge material.   There are so many sizes and products that will meet your needs.  We typically hold the non-structural variety in stock.  

For example we have a wide variety of 20 gauge material.  There is the 20 guage equivalent or 17 mil thickness.  These studs have strategic bends in that increases the structural value making them cheaper but still hold up to a 20 gauge standard.  Then there is the 30 mil product which is the standard 20 guage material.  It's a heavier product so its slightly more expensive.  But not as expensive as the 20 guage 33 mil product.  These studs typically come with an 1-5/8 or larger flange.  The 33 mil track comes with 1-1/2" leg.

There is so much to metal.  Come in and talk to one of our sales reps or we can get you in contact with the engineers directly.
