  1. Works Great But Fits Poorly When Hot 3 Star Review

    Posted by on Nov 25th 2020

    I've had my grillgrates for almost a year and they're awesome. Not much more needs to be said about their performance. If you've done your research you'll know that these are fantastic for uniform heat and creating perfect grill marks.

    BUT when I use them with my Weber Genesis II (for which my set is designed) the lid won't fully close once they're hot. At low temps they fit perfectly, but after about 500 degrees the cook box lid starts scraping against the grates and won't fully close. It nearly closes, but not completely. This happens every time I cook steaks and need the grill piping hot. It makes cooking times unreliable, especially on cold days when the outside air creeps under the lid. I live in Canada and grill year round, so this is a particular problem for me that I didn't struggle with using traditional grates. If these grates were designed to flatten at the ends it would eliminate the problem.

    All in all the product is great and deserves your money. Just be aware that the grates expand at high temps and may prevent your grill from fully closing due to their design.
    David- very surprised to hear this we've sold possibly a thousand or more sets. I am wondering if our size may be a bit long and we missed that? Also one thing to double check to is the shelf area in the back will get build up and that will start to nose the GG forward a bit? OR the grill is slightly off spec. I am private messaging you as well but want folks to see my reply. Brad

    Posted by on Oct 22nd 2020

    Took a BBQ class from Harry Soo and he introduced the Grill Grates to the class. Picked up a set and have been using them for a number of years. I just purchased the grates for my Weber Genesis. Great fit and as always, works extremely well.
    Harry Soo is one of the classiest guys in our industry. You are lucky to be able to attend his class! #grillgrateful

  5. Best thing i've ever done for my grill 5 Star Review

    Posted by on Jul 23rd 2020

    I read about GrillGrates from - I waiting until i purchased my weber grill before buying a set. I'm so glad I did! These grates don't disappoint. Perfect grill marks, and even cooking. I'm not worried about flare ups either.

    If you enjoy grilling you have got to give these things a try.
    We appreciate Meathead and his gang at THE Site for BBQ and Grilling!

    I’ve used my grates already for smash burgers, steak, wings, brats, and a few random cuts. I love the heat I’m able to get and the sear quality is awesome.

  9. What a Difference!! 5 Star Review

    Posted by on Dec 19th 2019

    Love the grills! Truly makes a difference for my Genesis. I couldn't afford a more expensive grill, but with these GrillGrates, I don't have to.

  10. Grill Grates convert 5 Star Review

    Posted by on Aug 16th 2019

    I use grill grates on a gas Weber. They were bought for the grill from new, I wanted to avoid the flare-ups of the past and these do just what it says on the box. Other than that, its grillin' as usual. The modular design is another bonus, I just unhook two from one end for adding a smoker box. That's a short review but I highly recommend these, I cant imagine going back to the old style of grate. Well worth the money.
