Crafted from heavy-duty cast iron, these 17.5-inch grill grates are designed as a direct replacement for multiple Weber Spirit, Genesis, and Silver/Gold series models. The material provides excellent heat retention and even distribution, helping to achieve consistent searing marks and reduce hot spots during cooking. Each grate features a pre-seasoned surface that supports natural non-stick performance over time, making it easier to release foods like steaks, chicken breasts, and vegetables. The solid construction resists warping under high temperatures and offers long-term durability for frequent grilling sessions. With a precise fit for models such as the Spirit 300/400, Spirit II 300, Spirit E/S-310 through E/S-330, Spirit 700, Genesis Silver/Gold B & C, and Genesis 1000-3500, these grates replace OEM parts 7638 and 7639 without modification. The cast iron material also helps maintain higher cooking temperatures, which is beneficial for achieving a good crust on meats. While the grates require regular seasoning to prevent rust and maintain performance, their affordability makes them a practical upgrade for users seeking better heat control and cooking surface quality. The weight and thickness contribute to a stable cooking experience, and the design includes adequate spacing for proper airflow and flame contact. These grates are suitable for propane and natural gas grills, and they are compatible with most standard Weber burners. The pre-seasoned finish is intended to reduce initial sticking, though additional oil-based seasoning before first use is recommended for best results.

The QuliMetal 17.5 grill grates offer a reliable combination of material quality, compatibility, and value, making them a sensible choice for both casual and dedicated outdoor cooks.
