How close to the border are you?
I buy a lot of my welding supplies and metal from our local welding company, Terry's Welding in Ardmore AL.
Two good steel suppliers are Limestone Steel, west Athens and Service Steel off of Schrimsher Ave. Since I moved to TN, I haven't used either in several years though.
Another possible source for both would be Russell Welding, north Washington Ave. I haven't been there in years either.
Good luck!
