Thinking about next year --
I want to build a frame so I can use 6 gas burners to boil on 3 full size steam pans. Eventually I can ditch the steam pans and get a similarly sized pan from Silver Creek that is 18x34 (almost a perfect fit).

Questions:
  1. Would iron pipe work to make the frame instead of welded angle iron? Any thoughts on pipe diameter?
  2. How much of a lip do I need for the edges of the pan to sit on?
  3. The fittings on the corners will be taller than the pipe (rails) so I'll plan on using arch/rail gasket to fill that void.
  4. Does the pan need any support in the middle or just around the edges?

Some photos I've collected over time to help visualize this idea:
