I would probably tend to use multiple kettles if needed for a large cook. Still there could be times your grate would be useful. I was thinking, if you can produce your grate in stainless, I was wondering what you could produce a full stainless grate for? I would really like to have one. Chrome plating eventually fails and rusts if neglected. Sometimes I think unplated steel would be better. At least it could be seasoned like cast iron.
