GasSaf Cast Iron Grill Grates for Weber Genesis 300 Series — Set of 2 19.5" x 12.9" Thick 0.5" for Even Heat & Sear

These GasSaf cast iron replacement grill grates (19.5" x 12.9" each) restore even heat retention and classic sear marks to compatible Weber Genesis 300-series grills.

If your original Weber 7524/7528 grates are warped, worn, or flaking, the GasSaf replacement pair brings back heavy-duty cast-iron performance without buying a new grill. Each grate measures 19.5 x 12.9 x 0.5 inches and comes as a set of two, giving you a full cooking surface of 19.5 x 25.8 inches when both are installed. These aftermarket grates are made of solid cast iron for heat retention and durability; they are designed to fit specific Weber Genesis E-310/E-320/E-330, EP-310/EP-320/EP-330 and S-310/S-320/S-330 models produced between 2007 and 2016. Note: they are not compatible with Genesis II 300 or Genesis II LX 300 series grills—measure your originals before ordering.

How do cast iron grates affect grilling performance?

Cast iron holds and distributes heat evenly, which improves searing and helps maintain steady grill temperatures. These GasSaf grates give pronounced grill marks and a consistent cooking surface, especially useful for steaks, vegetables, and thicker cuts that benefit from retained heat.

• Superior heat retention for even searing
• Heavy-duty thickness (0.5 inch) resists warping
• Creates clear sear lines and caramelization
• Requires seasoning to maintain non-stick surface

What care and maintenance do these grates need?

Cast iron performs best when seasoned and cleaned correctly. After initial seasoning, clean with a brush while warm, avoid soaking in water, and apply a light oil coat to prevent rust; periodic reseasoning will keep the surface non-stick and extend service life.

• Season before first use and after deep cleaning
• Brush food residue off after each cook while warm
• Avoid soap and prolonged soaking to protect seasoning
• Store dry and lightly oiled to prevent rust

Are these grates a direct replacement or aftermarket alternative?

These GasSaf grates are aftermarket replacements designed to match the size and mounting of Weber 7524/7528 units, offering a cost-effective option to restore your grill. They replicate original dimensions and function, but as aftermarket parts, you should confirm measurements and fit prior to purchase.

• Aftermarket alternative to Weber 7524/7528
• Exact dimensions listed for verification (19.5 x 12.9 x 0.5 inches each)
• Durable cast-iron material for longevity
• Sold as two pieces to replace both factory grates

Who is this for: The GasSaf cast iron grill grate set is for homeowners and outdoor cooks who own compatible Weber Genesis 300-series grills (2007–2016) and want to revive heat performance and searing capability without replacing the entire grill. It’s well suited to people who prefer heavy-duty cookware that can be seasoned and maintained for many seasons, and to anyone replacing warped or damaged factory grates with a robust, high-heat option.
