  1. GrillGrates is no doubt one of the best upgrades you can do to your BBQ. 5 Star Review

    Posted by on Apr 2nd 2018

    I purchased GrillGrates for my new Weber Genesis II E-310 grill. The grill came with heavy duty porcelain/cast iron grates; although I wanted to start grilling right away I waited for the GrillGrates to arrive. When I received them they were well packaged and came with the GrateTool which is perfectly designed for flipping and cleaning the channels. The GrillGrates fit perfectly. There are 5 panels in this set and I turned 2 of them over to get a griddle type surface. Next was seasoning them so I checked out the GrillGrates videos on how to do this. After a few cooks the GrillGrates were now blackened and had a non-stick coating. Also on the website was information stating that the GrillGrates run hotter than normal grates upwards of 200-250F, Now I cook at medium to low heat settings which saves fuel. Do yourself a favour and purchase some GrillGrates as you'll be totally satisfied with your decision.

    Best thing since sliced bread
    Best thing since indoor plumbing
    Best thing since hot water on tap
    Best thing since_____(well, I think I better stop right there) Get yours. I have three sets including the 18" Weber Smokey Joe, 22" Weber kettle and now my Pit Boss 820FB Deluxe Pellet Grill.

  3. Great Grates, but... 4 Star Review

    Posted by on Oct 31st 2017

    I love GrillGrates. I've recommended them to my friends. I had them in my old Weber I bought replacements for the Genesis II before it even arrived. I was disappointed to see the gap left on the side after installing the new grates. I'll still use them. I'll just have to be careful on the side.

  4. What a "Grate" Invention 5 Star Review

    Posted by on Oct 30th 2017

    I replaced the grates on a brand new Weber Genesis II after only 1 cook on the original grates. Of the 5 pcs. I installed the left 3 pcs. the normal way and the right 2 pcs. upside down. This broke the continuity for zone cooking. I did the steaks on the ridges and sauteed onions and mushrooms on the upside down side. What a "grate" meal. I have also seared a steak on the upside down pcs. and it does a total sear there.
    I am very happy with my purchase. Kudos to Brad for not only coming up with fthis idea but also for taking the initiative to develop and distribute such a fine product.

  5. Perfect Cooking and fit! 4 Star Review

    Posted by on Oct 24th 2017

    I love my Grill Grates but I was disappointed I was not offered 10% off as a returning customer. That is not fair.
    - Michael here with GrillGrate, we would be glad to get you that 10% off discount.

  6. Used Grill Grates to replace the grates on my beefeater built in grill 5 Star Review

    Posted by on Aug 7th 2017

    I needed to replace the grates on my beefeater built in gas grill because they started rusting. Grill grates fit my grill perfectly. So far they are a fantastic product. The grates clean so easily that it has cut the amount of time that it normally takes me to prepare the grill for grilling in half. I use a hickory wooden paddle that I run over the grill grates while it is hot which creates perfect cleaning grooves in my paddle which then enables me to very quickly clean the tops and sides of the grill grates without having to use any wire brushes etc. So far everything that I have grilled has come out perfectly. These grates are one of the best products that I have ever purchased and for my money these worth every penny that I paid for them.

  7. New grill, new to grillgrate 5 Star Review

    Posted by on Jul 21st 2017

    Awesome char on steaks and chicken first time out. Love em.
    Could be 1/16-1/8" shorter to make easier to close grill lid.

    Brad here Chris- make sure they are all the way to the back too. It is a close fit with the lid- I spent a lot of time at Home Depot with my head inside the new Genesis II series :-) impressive improvements

  8. The Final Touch 5 Star Review

    Posted by on Jun 27th 2017

    I used three sit on top panels with my old gasser and really liked them, I bought a new Geneses II E-310 NG and did a couple cooks on the stock grates and realized the stock grates are the missing link to a perfect grill. I ordered the direct replacement GrillGrates and turned my Weber from a Cadillac to Lamborghini, such a pleasure, temps are easy to control, even heat and the GrateTool is the icing on the BBQ.
