Grill Valueparts Matte Enamel Cast-Iron Cooking Grates for Weber Genesis 300 Series — 2-Piece Replacement Set, 12.9" x 19.5" Each

These two matte-enamel cast-iron cooking grates replace worn or damaged Weber Genesis 300-series grates to restore even heat, bold sear marks, and long-lasting performance.

If your Weber Genesis E/S 310/320/330 or compatible 300-series grill is showing uneven cooking or rusted bars, this 2-piece set from Grill Valueparts is sized and finished to match OEM performance. Each individual grate measures 12 9/10" x 19 1/2" (combined width 25 4/5" x 19 1/2") and is made from upgraded matte enamel cast iron to balance heat retention with corrosion resistance. The set is sold as a single pack of two grates and fits a wide range of Weber part numbers and model years.

Will these grates fit my Weber Genesis 300-series grill?

Yes — these grates are manufactured to the common dimensions used across many Genesis 300 models produced between roughly 2007 and 2016. They are intended as direct replacements for multiple Weber part numbers and model variants, though measuring your existing grates before ordering is always recommended.

• Individual grate size: 12 9/10" x 19 1/2".
• Two-piece set combined: 25 4/5" x 19 1/2".
• Compatible models include Genesis E-310, S-310, E-320, S-320, E-330, S-330 and EP/CEP/ESP variants.
• Replaces Weber parts such as 7524, 65937 and many listed OEM numbers.

How do these grates affect cooking performance?

The upgraded matte enamel cast iron construction provides strong heat retention and helps produce clear sear lines while promoting even temperature across the grill surface. Because cast iron holds heat well, the grates contribute to consistent cooking and increased caramelization, improving the texture and appearance of grilled foods.

• Matte enamel finish reduces sticking after seasoning with oil.
• Thick cast iron promotes even heat distribution and searing.
• Enamel coating resists rust, chipping, and cracking under typical grill temperatures.
• Durable design resists warping during regular use.

What care and maintenance do these grates need?

Proper care will extend the life of the enamel-coated cast iron: preheat, oil lightly before first use, and clean without harsh scrapers that can damage the enamel. Routine maintenance is simple and keeps the grates performing like new for many seasons.

• Apply a light coating of cooking oil before each use for a semi non-stick surface.
• Clean after cooking with a grill brush and warm water; avoid metal tools that chip enamel.
• Dry thoroughly before storing to prevent moisture spots.
• Replace if enamel becomes heavily chipped or underlying iron is exposed.

Which Weber replacement part numbers and model years match these grates?

These Grill Valueparts grates are listed as compatible with a long roster of Weber part numbers and many Genesis 300-series model years. They’re intended to be an aftermarket match for the original cooking surface geometry used across multiple generations.

• Listed compatible Weber numbers include 7524, 7528, 7566, 65937 and many OEM codes.
• Fitment covers Genesis 300 series models from about 2007–2016 and several EP/ESP/CEP variants.
• Works with a broad range of Weber gas grill part codes referenced in the product features.
• If unsure, compare the grate dimensions to your current grates before purchase.

Who this is for: This two-piece set is designed for backyard grillers and maintenance-minded owners of Weber Genesis 300-series grills who want OEM-style heat performance without the OEM price. It’s a practical replacement for anyone with worn, rusty, or damaged cooking grates who needs accurate sizing, improved searing, and a durable enamel finish that stands up to regular grilling seasons.
