The Stainless Steel Grate Valley Grill Brush


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.

Your new secret weapon will bring you from everyday grill enthusiast to newly crowned neighborhood GrillMaster known for creating professional level sear marks every time.

BONUS: Use GrillGrates rails up for traditional grilling, or flip them over for masterful flat top griddling. When you're done cooking on GrillGrates, cleaning your grill surface is easier than ever.

Note: While we recommend replacing grates on gas grills for maximum fuel efficiency, you can also use GrillGrates on top of your existing grates.



Never burn a steak again. The flame shield eliminates flare-ups. And the raised rails deliver the perfect sear.


GrillGrates can be configured to your needs. Create independent heat zones by separating the grates. Even flip over for an instant griddle!


Made from anodized aluminum, these grates will never rust out. When properly seasoned, they are non-stick and easy to clean.

    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!!

    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.

    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.

    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? 😉

    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!!!

    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.
