One more reason to go withe the solid SS grates from RCplanebuyer. I just restored a 3 or 4 year old Weber Spirit S-320. It came with the solid SS grates from Weber. Part number 7639 and they were rusted really bad. Not rusted through but even after scrubbing off all the loose rust they still looked bad like seen in the photo. And yes they are magnetic assuming it is 430 SS vs. 304 SS.
