  1. Why did I wait 5 Star Review

    Posted by on Feb 19th 2018

    I had looked at Grill Grates for a previous gas grill which I disliked due to temperature control issues and flareups. I didn't want to spend the money on that grill. What a mistake I made then. These grills have been a huge change for my new Weber. They allow me to grill with lower heat and I can safely leave chicken with skin, grilling and leave to prepare the rest of the meal. The grill marks are terrific too. Don't procrastinate any longer and do yourself a favor. Your family and friends will appreciate it.


  2. Should Have Replaced Earlier 5 Star Review

    Posted by on Jan 8th 2018

    All I can say is simply "WOW". I truly wished that I had replaced my cast iron grates for my 2003 Weber Genesis Silver B propane grill many years ago. I just cooked the best medium ribeye steak with no flair ups and without a sous vide device to a perfection! The second item that I cooked were teriyaki pork chops for my daughter's birthday party without any flare ups which I have to fight with each time I grill these due to the sugar in my marinade - was not even an issue and the teriyaki flavor was more evident with the grill grates. Ordering was easy and quick, told them I wanted to replace the grates on my grill, told them what the grill was and they responded the same day to tell me which set to purchase - best grill purchase replacement part that I have ever bought for my grills, hands down.

  4. Love these grates 5 Star Review

    Posted by on Sep 29th 2017

    I really love these grates and I think they will last a long time. I love how they cook and I love the fact they won't rust. I've used them 3 times and I am looking forward to more cooking on the grill.

  5. Even Heat all the Way Through 4 Star Review

    Posted by on Sep 13th 2017

    I have cook only once since receiving my Grill Grates and hand picked two sirloin steaks of the same size. Preheated grill and through them on. Cooked at same temp and for the same time and they both turned out perfectly medium rare with no burning or flare ups. Couldn't be happier and the whole family said it was the best tasting London broil they've had in a long time. Thank you for making my life so much easier. The only thing I would want is about 3/4-1 in wider to cover the entire surface.

    Food doesn't stick. Even cooking. Rare small flare up when cooking burgers but nothing like before. Waited a long time before getting these. So glad I did!!!

  7. Great Product 5 Star Review

    Posted by on Sep 5th 2017

    I have an older Weber Genesis Silver B Grill and I thought I would try the Grill grate system I have replaced the cast iron grates and I must that there a big difference in heat control and regulating the temperature and it uses less propane I liked these so I ordered a set for Weber Q1000 gas grill that use in the fire place in my kitchen and some accessories it a great product and I rate it at 5 stars

  8. great grill grates. 5 Star Review

    Posted by on Aug 28th 2017

    Fit the weber spirit 300 perfectly. Cooked ribs on the grill and they were prefect. Set the temp at 200 degrees using one burner. Put some hickory chunks under the grate and above the burners on a metal box. It smoked very well. Went inside for 2 hours, then wrapped them and continues to cook for about 2 hours. I even put some bbq sauce on them at the beginning and they did not flame up. With greasy ribs, you may get the occasional flare up, but I did not have that problem.

  9. 70 to 700 Degrees and No Flare Ups 5 Star Review

    Posted by on Aug 8th 2017

    Install takes about 5 seconds. Front to back fit close enough to perfect. Side to side leaves 1/2 inch on each side so near perfect. Aewsome tasty grill marks on steaks and chops, still getting the hang of chicken, it's me not the grates. Being able to put sugar BBQ sauce on during the cook instead of just the last few minutes is a plus. At first it starts to look like these are going to get nasty and fill up the lower channels, valleys, with grill mess but each cook out seems to self clean without a whole lot of brushing, some brushing is needed and for really tough loads of sticky BBQ sauce a putty knife does the trick on the very top grill mark making surface. If you have read this far I think you need to go ahead and order a set for your grill. They are nice and you will love them.

    The Grill Grates are expensive so I was happy that they perform better than I expected. I was not disappointed. They do heat evenly and flair-ups are nonexistent for me. The design of the Grill Grates suppresses flair-ups nicely. The four prong Grate Tool is much sturdier than I expected and works well turning even the heaviest of steaks. I find the Grill Grates no harder to keep clean than any other grates. The Grate Valley Grill Brush works well clearing the deep channels of the Grill Grate. Since Grill Grates are aluminum they will never rust out and should provide years of service, justifying the initial purchase cost. If I had to do it over I would buy the Grill Grates again and I recommend them without hesitation to friends.
