QuliMetalSUS304 Grill Grates for Weber Spirit 300 and GS4 Spirit II 300 Series, Spirit 700, Genesis Silver B & C, Genesis Gold B & C, Genesis Platinum B & C, Genesis 1000-3500

These were everything promised, and I am still amazed.These grates arrived in a slightly beaten box (not surprising, as they are heavy). The contents were in perfect condition.I initially was waffling on these (0.5 mm) or the slightly heavier 0.7 mm grates. The old-man cheapskate in me decided to save the few dollars and went for the cheaper set. For once it paid off! I am seriously not disappointed.I first did a magnet test (with a heavy neodymium magnet) and it fell off like I was placing it on a piece of wood.I then installed it in my ancient Weber Genesis Silver B grill and they fit perfectly. Upon initial heating they turned a quite pretty blue, and did not show any signs of warping, twisting, or bowing. Rock solid.Now... after two + months of use, I can say these are performing admirably. There is no signs of rusting (and I frequently use salt-laden marinades). And, they remain flat and straight. The pretty blue color has been replaced by a yellow-brownish overall color, but nothing I would not expect from a normal grill grate.I will be the first to acknowledge, that I do NOT follow (more often than not) the routine care guidelines( (pre-cook oiling, and diagonal scrubbing). Yet, in spite of my own laziness, these grates are performing admirably, and brush (with a stainless steel grill brush) clean with a minimum of effort. Do they look "brand new, out of the box?" Of course not... remember, I am lazy. But... do they perform with a minimum of sticking (better than the seasoned original cast iron grates that I went through three sets of)? Heck yes!!!When I do remember to treat them the way they should be.... a burn-off, followed by a brush-down, and maybe a coat of vegetable oil, they clean right up and are ready to go again.I am not sure what else to say. The welds are solid, they fit perfectly, and the perform better than I hoped.I would buy these again without a second thought, and have already recommended them to several of my friends.

Good quality, heavy cast iron. Perfect fit.

I have decided to switch from original black metal to this beautiful stainless steel grid. Very happy with results. Perfect size and easy to install and clean.Highly recommend.

Heavy duty, true high quantity stainless steel. Perfect fit.

These fit very well on my Spirit. I had to make no adjustments at all. Simply remove your old grates and set these on the pegs. Nothing has skipped a beat when it comes to my grilling. I'm not sure they are made or are coated with the exact same formula/metal but they are holding up well. Nothing is sticking or otherwise acting differently than what I had before. You will need a bit to get these seasoned. Don't do anything differently, just know you'll need some time.Really pleased with these replacements.

Super heavy duty. Much better than the original cast iron

Bought my Weber Spirit 300 in March 2019. It’s a natural gas model. It’ll easily go to 600 degrees. The original grates lasted 3 years. March of 2022, I purchased these 9mm stainless replacements and after 2-2/2 years, they’re still shiny if you scrub off the seasoning. Why is that impressive? We live on the coast in FL and everything rusts. Plus high heat adds to the rust. Plus salty foods help it rust too. Yet after 2-1/2 years, they’re not rusted. I just clean them with a wire brush and hit them with some cooking spray to re-season and that’s it. And props to Weber. The grill has lasted longer than any grill I’ve ever owned. I expect this same setup will be running 5 years from now. These replacement grates are an excellent investment.

Fits great and wow are they heavy duty! Spend a little more on these, you will not be disapointed.
