Basement perimeter wall construction
My basement has a full perimeter sump pump; drainage mat on wall from 1 foot below ground level to loop into the plastic cove that empties to the sump drain below; limestone foundation walls; penetrating sealer on the concrete floor.
I plan on installing light steel perimeter walls where no steel will touch the limestone foundation walls. Closed cell spray foam, treated with a fire barrier, will be installed professionally after plumbing and electrical runs are completed.
Behind the utility sink area, I plan on installing galvanized steel panels. My question is will I meet codes if I install the panels directly on the steel studs or do I have to install paperless drywall before installing the steel panels?
I do want to meet or exceed all applicable codes and I also plan on checking with my local building department before proceeding. But I want to understand my options first.

Make sure that there is plenty of room between the steel studs and your foundation walls. I would aim for between 2 and 3 inches -- enough room so the spray foam contractor can get plenty of foam behind those steel studs. The steel studs are a thermal disaster, so a fairly substantial foam layer behind the studs is essential.

I can't think of any reason why you can't install galvanized steel panels on your studs, but of course your local code authority will have the final say.
Hi Martin. Thanks for your response. I'll make sure the steel studs are positioned away from the foundation as you suggest. Thanks, again!
