Smoker build question

[basicsmoker97]

Hello I'm new here, I'm building a cabinet type smoker, I have a few questions.
1- I'm building the cabinet out of mild steel and do you need to remove the mill scale on the steel on the inside of the cabinet?
2-what kind of stainless steel do I need for the racks?
Thank you Steve :usa:

Remove the mill scale and oil, from processing..... mild steel expanded metal works for grates.... coat both with cooking oil and heat to set the oil for a good coating.... repeat as necessary..... 304 SS is cheaper than 316 and works very well.... whatever is in your budget... expanded metal needs a framework to support it...
