The Best Grilling Accessory You’ll Ever Buy for your Weber Genesis® II 400 Series.

Nobody wants a burnt or dry meal. Flare-ups can quickly ruin any backyard cookout. At GrillGrate, we believe that grilling should be easy, fun, and stress free – every time. All you need is GrillGrates for your grill.

GrillGrates are a must-have accessory for your gas grill. Whether you sit them on top of your current grates, or use them to replace your factory grates, GrillGrates will make your old gas grill better than new. Made of hard anodized aluminum, they never rust. GrillGrates are reversible, interlocking panels, giving you two grill surfaces in one. Even out those hot and cold spots with GrillGrates and produce juicier, more flavorful food. GrillGrates make everyone a better, faster, more confident cook. The Hard Anodized Aluminum and Raised Rail design promote conductivity and control for juicier, more flavorful food. Steakhouse quality sear marks, guaranteed! Here’s why:

  • Non-stick Hard Anodized Aluminum Interlocking Panels
  • Two-in-One Surface; Rails Side Up for Traditional Grilling & Flat Side for Flat Top Griddling
  • Rust Resistant Material


  • Faster cooking
  • Simpler grilling with better results
  • Reduced flare-ups
  • Versatility
  • Easy to use and clean
  • Light and transportable

Your Grill, But Better. As opposed to traditional grill surfaces that merely just hold the food above the heat source, GrillGrates concentrate heat through the patented raised rail design cooking food faster and more evenly. GrillGrate’s air flow vents and flat side work together to trap grease, prevent charring, and block those pesky flare-ups that tend to engulf and dry out food. When we say better, juicier food every time – we mean it! It is central to the innovative design of this grate. The sizzling-hot valleys vaporize drippings and juices, retaining moisture and enhancing flavor.

  • Assembled dimensions = 18.8” deep x 32.575” wide

  1. RL

    Love the consistent heat dispersion across the entire surface – or section, if you so desire. The fat run-off and sizzle process add to the quality of the food flavor. Still have to watch out for grease fires – not sure there are fewer versus using standard grates.

    The big benefit is knowing that the surface temperature is the same from one side to the other.

    All that’s left for Grill Grates to do is to make these out of highly rust resistant stainless steel instead of aluminum.

  2. Gerry

    Perfect so far. Cooks great!

  3. AFarris

    Fit great. If you had a set, you’ll always have a set. If you haven’t tried them, these are by far the best accessory to any grill I have ever purchased.

  4. Dennis G

    I would recommend this product for natural gas grills. I have always had issues creating a good sear w/o overcooking my meats. With Grillgrates; I am able to obtain a great sear and not overcook.

    My Genesis 400 series came with SS grates. I used them for a couple of weeks and realized I did not care for them. I have used Webers’s enameled grates on a past weber and I preferred them. Prior to ordering the Weber product, I researched other options and came across Grillgrates. I read all the positive reviews and ordered them. The set arrived in a timely fashion and they fit very well on my grill. The gap panel was used to fill in the far left side of the grill. My first use was cooking up some Rib Eyes and I do admit the cooking was more even, no flareups and did in fact heat up faster than the grates that came with my grill. I have used the grillgrates only a few times, but I can see it is an improvement over the stock grates. So far , I am happy, but I will reserve final judgement after using them for a few months.

    This is my second set for a 2nd grill I have. The first set of Grill Grates were a gift from my daughter and after several months of usage I am a strong “believer”. I think they are a wonderful upgrade to both my 3 and 4 burner Weber Grills. We grill all our meats, seafood and most vegetables 5 to 6 nights a week all year long and these grates give me an even heat distribution that results in a great sear, food cooked more evenly all over the grill and it cooks at a much lower heat. Now, instead of 500 to 700 degrees I do the same thing at 300 degrees and with fewer burners. We have our grates split with the flat side up on 1/2 of the grill. The grates seems to be to be a little expensive but they are amazing and I do recommend them.

    These grill grates are very useful. Yes, it also heats up the grill faster as well. It leaves awesome grill marks on your food and it does make your food juicer. No flare ups!!

  8. Harry Sach

    If you own a Genesis, you know who crappy the cast iron grates are. They take forever to pre-heat….and they cool off quickly. The “Flavorbars” are a joke too.

    With the Grillgrates….pre-heating time is cut down from 30 minutes to 10….the grill marks are insane….cooking time is a lot faster…and the valleys of the Grillgrates give you food a much better grilled taste than the “Flavorbars”.

    But these now and thank me later.

  9. William

    Great quality product. Perfect fitment on my Weber. Easy to clean amd cook on. Very impressive grill marks. Just follow the instructions from them and you will be ok. I would buy again if needed.

  10. Jim Morris

    I’ve had a full replacement set of Grillgrates on my Weber Genesis Silver A 2 burner for almost 2 years, and a set on my Weber Performer 22.5″ kettle as well, for longer than that. When I recently found a Weber Genesis II E-410 4 burner on clearance for $399, I took it home the day I found the deal, but did not even bother to cook on it until my full set of Grillgrates came in for it! It just makes the grilling/griddling/cooking experience so much better, and eliminates flareups on gas grill so much.

    P.S. anyone need a set of never used cast iron grates for a Genesis 4 burner? 😉

  11. Dr. G

    If you’re like me, you’re probably still researching, and/or thinking about possibly buying these grates. Since I purchased them, I have come to realize that these grates are incredible! My cooks use much less gas, so I’m conserving there. The food is more moist, and flavorful! I highly recommend these grates! You too wil love them!!!

  12. Mike Watson

    This is the very best grilling surface I have ever used. I use them on a Weber Genesis. No hot and cool spots and no flare ups. I would have given them a perfect 5 stars but I feel they should fit better. They are about 1/4 too short, Seems like they are about to fall into the grill. If I ever need a new grill I would absolutely get Grill Grates again , But I would custom order them for a better fit.

    Hey Mike, Michael here with GrillGrate. We have found if we go with full front to back coverage the lid will not close properly on Genesis and will end up resting on the GrillGrates. That is why they are a little short but trust us, they will not fall in.
