GrillGrates are made of Hard Anodized aircraft grade aluminum that will last a lifetime. Two interlocking GrillGrate panels and the GrateTool are packaged as a grilling gift kit that works with any grill- gas or charcoal. No more burned and dried food and bring on the sauces and marinades! The hard anodized finish resists foods sticking and the rails brush perfectly clean with a wire brush and a bit of water just like restaurants clean their griddles.
