GGC Porcelain-Coated Cast Iron Grill Grates 2-Pack 12 3/8" x 19 1/4" — Heavy-Duty Replacement for Weber Nexgrill Jenn-Air

These GGC porcelain-enameled cast iron grill grates are two heavy-duty replacement cooking grids (12 3/8" x 19 1/4" each) designed to restore even heat and classic sear marks to compatible Weber, Nexgrill, Jenn-Air, Charmglow and other grills.

If your original cooking grates are warped, rusted, or scored, this pair of porcelain-coated cast iron replacements provides a reliable aftermarket option. Each grate measures 12 3/8" by 19 1/4" and together they cover 24 3/4" by 19 1/4" when installed side by side. The porcelain enamel finish helps resist sticking and simplifies cleaning while the cast iron core retains heat for steady cooking and better searing.

Will these grates fit my grill model?

These grates are made as compatible replacements for a broad range of models across multiple brands. Before ordering, match the 12 3/8" x 19 1/4" dimension of each grate to your original parts and verify the manufacturer's model compatibility list.

• Compatible with many Charmglow, BBQ Grillware, Aussie, Costco Kirkland Pro Series, Nexgrill, Jenn-Air, Grill Zone, Weber Genesis, Presidents Choice and Perfect Flame models.
• Specific model numbers are included in the product details for cross-referencing.
• Measure the width and depth of your existing grates to confirm the fit before purchase.

How do porcelain-coated cast iron grates change cooking performance?

Cast iron stores and distributes heat more evenly than thinner materials, which improves searing and temperature stability. The porcelain coating provides a smoother, easier-to-clean surface and reduces food sticking compared with bare cast iron when properly preheated and oiled.

• Superior heat retention helps maintain consistent grill temperatures during searing.
• Porcelain enamel minimizes rust and simplifies cleanup with routine brushing and wiping.
• Heavy construction yields durable service life under regular grilling conditions.

What maintenance does porcelain-coated cast iron require?

Care is straightforward but important to preserve the enamel. Avoid metallic scrapers that can chip porcelain; instead use a soft-bristle brush and warm water for post-cook cleanup. Periodic seasoning with a light coat of cooking oil keeps food release reliable and helps protect the coating.

• Clean after each use with a nylon brush and warm soapy water; dry thoroughly to prevent moisture buildup.
• Lightly oil the grates after drying to maintain a non-stick surface and protect enamel edges.
• Avoid thermal shock from pouring cold water on a hot grate to reduce risk of enamel damage.

Why choose aftermarket GGC replacements instead of OEM parts?

Aftermarket grates like these GGC units offer a cost-effective way to restore full cooking function when originals are damaged, discontinued, or costly. GGC designs these grates to match popular OEM dimensions and to provide the same cast-iron heat properties with a porcelain finish.

• Economical alternative when OEM parts are unavailable or overpriced.
• Constructed from heavy-duty cast iron with a baked-on porcelain enamel for durability and ease-of-cleaning.
• Sold as a two-piece set to replace both cooking grids for consistent surface coverage and appearance.

Who this is for: Grill owners who need a full set of durable cooking grates to replace worn or damaged originals, especially those with compatible Weber Genesis, Nexgrill, Jenn-Air, Charmglow, Costco Kirkland Pro Series and similar models. Ideal for backyard cooks who want cast-iron heat retention and easy-clean porcelain finish without paying a premium for OEM parts—just check the 12 3/8" x 19 1/4" grate size against your current grills before ordering.
