I have been looking into these but not many folks reviewed these under their pellet grills. Plenty of reviews under Weber and Kamado grills. These grates are suppose to get 100 - 200 degrees hotter than the rest of the grill and the same goes for other types of grills but even higher temp increase or difference. They are anodized aluminum.
GrillGrates are a revolutionary grilling surface that can sit on top of your existing grill surface or replace entirely. GrillGrates eliminate flare ups, evens out the heat, never rust and will give new life to any grill. Take your grill game to the next level with GrillGrates
