Those are usually "stand alone" pieces of metal for a firewall also and quite heavy compared to what we need on the KR. We have the 1/4" ply for structure and the "fiber frax" for flame barrier, so the stainless can be rather thin and light. In the case of the KR the stainless is just there to protect your fiber frax from damage. I don't know what thicknesses the galvanized comes in but I've never seen anything as light as say .007. Could be though....... Larry Flesner
