These FlameDuty 7524 porcelain-enameled cast-iron grates are a two-piece direct replacement for Weber Genesis 300-series grills, delivering superior heat retention and distinct sear marks. Designed to be a drop-in match for Weber Genesis E-310/E-320/E-330 and S-310/S-320/S-330 (2007–2016) models, this 2-pack replaces original parts 7524 and 7528 and restores your grill’s cooking surface to like-new performance. Each grate measures 19.5 x 12.9 inches for a combined cooking area of 19.5 x 25.8 inches, giving you ample room to cook multiple items at once while preserving the factory fit and mounting points.

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

Yes — the FlameDuty replacements are manufactured to match OEM dimensions and mounting points for compatible Genesis E and S 300-series models from 2007 through 2016. They are intended as direct substitutes for parts numbered 7524 and 7528, so installation requires no modifications.

• Compatible models: Genesis E-310/E-320/E-330 and Genesis S-310/S-320/S-330
• Exact sizing per grate: 19.5 x 12.9 inches
• Sold as a 2-pack to replace both original grates simultaneously
• Designed to align with factory mounting tabs and supports

How do these cast-iron grates perform compared to porcelain-coated options?

FlameDuty’s heavy-duty cast-iron core with a porcelain-enameled finish combines the heat retention of cast iron with the easy-clean properties of porcelain. Expect stronger sear marks and more even heat distribution than thin steel grates, while the enamel helps reduce sticking and simplifies routine care.

• Superior heat retention for consistent searing
• Prominent grill marks and caramelization
• Porcelain enamel reduces food sticking and simplifies cleanup
• More durable and less prone to warping than thin steel grates

What maintenance steps keep these grates performing and rust-free?

Caring for porcelain-enameled cast iron is straightforward: season and clean them regularly to protect the surface and prevent corrosion, especially if you grill near salty air. Follow a brief preheat-and-oil routine before first use and reapply oil periodically to maintain the enamel and minimize food residue buildup.

• Preheat grates to 500–600°F for 10 minutes before cooking
• Brush with a small amount of olive oil, then reheat to set the surface
• After use, brush off debris and wipe with a lightly oiled cloth
• Store dry and avoid prolonged exposure to salt or moisture

Why choose this FlameDuty 2-pack instead of replacing a single grate?

Replacing both grates at once ensures consistent cooking height and even wear across the cooking surface, restoring balanced heat distribution and matching appearance. Buying a set also avoids mismatched patina or performance differences that come from pairing a new grate with an older, worn piece.

• Uniform cooking surface and sear quality across the entire grate area
• Identical fit and finish on both sides of your grill
• Convenient swap-out to restore original factory geometry
• Better long-term value than replacing individual pieces over time

Who is this for? This FlameDuty 7524 replacement set is for grill owners who need a precise, durable substitute for worn or damaged Weber Genesis 300-series grates. Choose it if you want stronger searing performance, improved heat retention, and a porcelain-enameled surface that’s easier to maintain than bare cast iron. It’s also a good option for anyone restoring an older Genesis to full cooking capability or upgrading aftermarket grates for consistent results.
