What gauge sheet metal?

[questor]

3.5 deep X4.5 wide X6 high oven. What gauge do I need inside to stand the heat? I'm going to use propane burner on bottom heating 1/4" plate.

im going to use 20ga, id say thats the minimum thickness you would want.

i picked up 5 5x5 20ga galvanized steel sheets yesterday for $15 apiece!!!
