Internal Garage Wall Ideas/Suggestions

I needed a wall between my basement and whats just crawl space. I used painted steel that was once a above ground pool wall. It looks like wood paneling on the face side. The framing is treated 2X6 that was once a deck behind a mobile home. Studs on 2 ' centers.
Access door is 1/4" corrigated styrene that was a Coca-Cola display in a convienence store.
My only expence was nails, screws, and couple sticks of vynil used to join and/or cap vynil lattice. The backside is insulated with 3/4 styrofoam. It was free too.
