I have a masonry offset smoker and I am installing a new steel firebox door. The angle iron frame and the steel plate door are both of 3/16" thick steel plate. The door measures about 20" tall by 14"wide. It will be hinged on one side. The door with have a few holes in it for damper air inlets. Below is a picture of the firebox opening:
Is a 3/16" thick steel plate door thick enough so that it isn't going to warp when I fire this thing up? Do I need to add some sort of reinforcing frame around the edge of the door?
Thanks for any knowledgeable input.
