lance sheet metal

Look up U.S. Steel in your area. May be some other steel company in your area. They sell just about any types of metal you would want to buy. steel, aluminum etc. comes in sheets of thickness you want. You normally place order and they will cut to size. You do need to do some research on grade and gauge you want etc. The pocket ref books from most hardware stores will point you in the right direction for gauge etc. Keep in mind metal has gone up in price a lot. I just paid $4 a foot for some 2" by 1/4" angle. Yup it was YIPES!!

BTW I just google and found Harbor Steel and Porter Steel in Muskegon and American Steel in Grand Rapids. Don't think you should have any trouble finding what you want.
