So, I am in the middle of a build of an old commercial freezer. I have decided to split it into two smoking chambers. Now, I have completely extinguished my stainless steel fund. I went to a local auto parts store and bought two sheets of steel to divide the chambers. My problem is that I dont know if this steel is galvanized. Is Galvanized that bad to have in a smoker (only going 240 degrees)? I found some cheap aluminum, should I use that instead? Any problem solvers out there? Thank you for all your help!!!
