GrillGrates are the No. 1 ranked grill surface in America! Made in the USA from hard anodised aluminium which will never rust, they have patented raised rails with a flat base plate interspersed with holes for airflow. It is this design that amplifies the heat and eliminates hot-cold spots, whilst the bottom plate protects food from flare-ups. In addition, drippings are vaporised in the valleys adding flavour and moisture to food. For an added boost of smoky flavour, you can sprinkle some wood pellets in the valleys.
