  1. Wonderful grill upgrade 5 Star Review

    Posted by on Oct 20th 2020

    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.

  3. Please Don't Hesitate Any Longer 5 Star Review

    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!!!

    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? ;)

  5. Awsome Product 4 Star Review

    Posted by on Jul 16th 2018

    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.

  6. Awesome 5 Star Review

    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!!

  7. BUY THESE NOW 5 Star Review

    Posted by on Dec 8th 2017

    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 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.

  8. awesome grate 5 Star Review

    Posted by on Jul 26th 2017

    Works as well as the videos you see. I bought a natural gas e410 grill and never even used the stock grates. Put in grillgrates from day 1 and am absolutely loving the meats that we cook. Amazing flavor and so much easier to cook / clean.
