The Best Grilling Accessory You’ll Ever Buy for your Weber Spirit 300 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.

PLEASE NOTE: If using this set on a new model Spirit, you will experience about a 2″ gap. We recommend either centering the set to have a slight gap on either side or separating your grates in the middle for two-zone grilling.

The magic equation:

GrillGrates + your gas grill = Carefree grilling and juicier food!

These reversible interlocking panels replace the existing grates on your gas grill, and immediately kick your cooking up a notch. Flare-ups are no longer a concern as heat concentrates up the raised rails, making burnt, charred and dry food a thing of the past. 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.

THE BOTTOM LINE: Hard anodized aluminum GrillGrates lock in flavor by vaporizing moisture and heating food evenly in its own natural, juicy steam. The direct heat delivered by our patented raised rail design easily locks moisture and flavor into your food - where it should be. Ready to get started?

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.

    So far, so good! Grates fit well (a bit of extra room on the side, but it makes moving and repositioning easier). Five meals cooked so far… and zero flare-ups! I’m eager to try flipping the grates and using them as a griddle (with holes) surface.

    I’ve received and used my new Grill Grates just once. I removed my original Weber Spirit 310 grates and scraped away every internal grilling deposit I’d made over the last year; then I placed the Grill Grates where the old cast iron grates were. A perfect fit that provides air circulation from both right and left.
    I fired up the grill to about 400 degrees, cut a whole onion in half and, using the new Grill Grate gloves, I wiped the tops of the Grate rails for about 3 minutes, until I could see that the onion discolored the rail tops. I had checked the rail top temp with an instant read thermometer. Wow! A 400 degree grill temp produced just over 500 degree rail tops!
    Now! I placed two beautiful 1-1/4” thick NY Strip Steaks, previously prepared, onto the rails at a 45 degree angle. I closed the lid and after about 1-1/2 minutes I rotated the steaks 90 degrees. About 1-1/2 minutes later I flipped the steaks over and witnessed the most perfect grill sear-marks I’ve ever created. After repeating the grill process on the back side, the internal temp was 230 degrees.
    We cut into the best looking medium rare steaks ever! I’m completely sold!
    Now to use the flat plate side for some veggies.

    Exceeded my expectation. Really works as promised.

  5. Dean S. (verified owner)

    Wouldn’t use any other grate, BUT the flat side should be considered the A side.

    Only used it once so far but it worked great. Super grill marks and sear.
