Grillflame Cast Iron Grates for Weber Spirit 300 Series – 17.5 x 11.9 in (2-Pack)

Upgrade your Weber Spirit grill with Grillflame cast iron grates

Elevate your outdoor cooking with a two-piece replacement set built for durability and performance. Each grate is crafted from cast iron and finished with a matte enamel coating, offering a sturdy feel and strong heat retention that stands up to high-heat searing. The result is steady, even heat across the grate surface and the potential for rich caramelization without the fragility seen in some porcelain-coated alternatives.

Why these grates stand out

• Durable construction: Cast iron with matte enamel resists rust and remains solid during hot searing sessions.
• Even heat and sear-ready: Heavier core supports uniform heat distribution for reliable results across the surface.
• Low-maintenance seasoning: With proper oiling, the surface can develop a natural non-stick patina over time and becomes easier to clean.
• Broad compatibility: Designed to fit Weber Spirit 300 and Spirit II 300 series, plus select Genesis/GS4 configurations, offering flexible replacement options.

Package details and fit

• Includes 2 grates, each measuring 17.5 x 11.9 inches; total coverage is 17.5 x 23.8 inches.
• Compatible with a wide range of Weber models; for best results, measure your grill grids to verify a precise match.

In everyday use, these grates can translate to a satisfying sear on steaks, mushrooms, or vegetables, while maintaining temperature consistency across the cooking surface. The matte enamel finish helps resist chipping and provides a more robust appearance compared with some lighter coatings. Regular seasoning and gentle cleaning help preserve the surface and heat performance over time.

Tips for best results include preheating adequately, applying a thin layer of oil to the grates before cooking, and avoiding aggressive scrubbing that could wear the coating. With routine care, these grates can contribute to a dependable grill setup that supports flavorful results and easier maintenance.

Fit and care guidance

To ensure a proper fit, compare your grill model and grate size with the compatibility notes. Clean while warm and follow this surface-friendly care routine to help maintain the matte enamel finish over the long term.
