I recently visited the Surplus City store at 1880 Carlisle Pike, which is about 1.5 mile east of your hotel. It would be just past the Middlesex Diner in case you eat there. They have a lot of steel supplies, including sheet and sq/rect tubing, exhaust pipe and mufflers, and fasteners sold by the pound. You may as well check it out while you are in the area. They also sell body shop supplies, but I didn't really look at them.
