I have given that a lot of thought. A removable steel sturdy channel will go from side to side up top but actually attached to the side sheet metal for hanging parts. For the heavy parts I am welding up a steel bakers rack that will roll right into the oven. The other option is to take the finished ceiling section that is sitting on top of the 3 walls and attach the 18 ga sheet metal to the ceiling and then re-attach it to the walls. So the 18 ga. would be secured 3 5/8" all the way around the 3 walls.
