They are perfect for cooking a variety of foods and help achieve professional-looking grill marks on your dishes. For optimal performance, it's recommended to season the grates before their first use Porcelain Steel Grill Replacement Parts: The flavorizer bars and heat deflectors are made of porcelain-enameled steel and have distinct yet complementary functions. The flavorizer bars evenly disperse heat, catch drippings that infuse food with a smoky flavor, and shield burners from grease drippings, while the heat deflectors direct heat toward the cooking surface, prevent direct flame exposure, and ensure more even heat distribution 7524 Cooking Grid Grate 7621 Flavorizer Bars 7622 Heat Deflector Replacement Grill Parts
