B-Side BBQ out here does the sheet pan and liner thing as well. I forgot about that, but, I love it for BBQ. Much better feel than a basket or plate for a BBQ place.
That is a 1/4 steel sheet pan, any baking supply store should be able to supply them in bulk, and for around $4 to $6 each. Not all that cheap, but, they do not break, rarely bend, survive the sanitizer easily and look better with age.
me: I don't drink anymore
Yelonutz: me either, but, then again, I don't drink any less
