What GA Metal?

[R. Hutchins]

I plan to have a local sheet metal shop make an extension ring to fit into the rim of my 22.5" OTG that will be 9-10" tall. The purpose is to make an oven for wood smoked pizza. I will have them cut an arc in the ring for a door. My plan is to make the arc with a chord of about 17" which will make the height of the opening at the center about 4.5".

Do these dimensions sound about right? Would you recommend different ones?

What gauge sheet metal would you recommend?

What type of sheet metal? Aluminum? Stainless? Brushed steel?

Get the metal shop to quote on all three metals with medium to heavy gauge (18 - 22), stainless will be the best but how much are you willing to spend ??

I think you might be better off buying a BBQ Stacker and having the shop cut the hole and make a door. Stacker is only $140 and it's SS. No shop can invest a one time setup for that amount (unless you're related to them).
