About This Designed for Genesis 2025+ Gas Grills: Specifically engineered for Weber Genesis 300 & 400 Series gas grills released in 2025 and newer, including E/S-325, E/S-330, E/S-335, E/S-435, E-430 and EX-335 Smart models. Sizing is optimized for the updated firebox structure used on newer Genesis grills. Matte Porcelain-Enameled Cast Iron Construction: Constructed from solid cast iron with a matte porcelain-enameled surface, these grates deliver strong heat retention while helping reduce sticking. The enamel coating protects the cast iron during frequent high-heat grilling. 2-Piece Split Design for Full Genesis Coverage: Includes one 18.9” × 10.4” grate and one 18.9” × 16.5” grate, designed to match the split cooking surface of Genesis 2025+ grills. The two-piece layout allows easier handling and stable placement. Even Heat for Consistent, Defined Searing: Heavy-duty cast iron stores and distributes heat evenly across the cooking surface, helping create deep, well-defined sear marks on steaks, burgers, chicken, and vegetables. Easy Cleaning with Durable Enamel Finish: The porcelain-enameled surface cleans easily with a grill brush after preheating and requires less maintenance than bare cast iron. Smooth edges improve handling safety during installation and routine cleaning.
