Weber Porcelain‑Enameled Cast‑Iron Replacement Grates for Genesis 300 Series (2007–2016) — Set of 2, Superior Heat Retention

These two porcelain‑enameled cast‑iron cooking grates replace the primary grates on select Weber Genesis 300 series grills, restoring heat retention and searing performance.

If your Weber Genesis 300 series grill (models produced 2007–2016) needs new cooking surfaces, this set of two porcelain‑enameled cast‑iron grates is designed to match the original fit and cooking characteristics. They are engineered to hold and distribute heat well for consistent searing, and their enamel finish helps resist rusting when used and maintained correctly. Note that these grates are not compatible with Genesis II, Genesis II LX 300 series, or Genesis models manufactured since 2022.

Will these grates fit my Genesis 300 series grill?

These replacement grates are manufactured to fit Genesis 300 series grills built between 2007 and 2016. Compatibility is model‑specific, so confirm your grill’s series and year before ordering to ensure a correct fit.

• Fits: Genesis 300 series (2007–2016)
• Not compatible: Genesis II or Genesis II LX 300 series
• Not compatible: Genesis models produced since 2022
• Sold as a set of two grates to replace the primary cooking surface

How do these porcelain‑enameled cast‑iron grates affect cooking?

Cast iron stores and radiates heat effectively, yielding stronger sear marks and more even cooking across the surface. The porcelain enamel coating creates a smoother, more rust‑resistant exterior that’s easier to wipe clean after use.

• Superior heat retention for consistent searing
• Porcelain enamel reduces sticking and corrosion risk
• Creates clear grill marks and even browning
• Heavy duty construction supports long‑term use when cared for

What care and maintenance do these grates require?

To keep enamel cast‑iron grates performing well, preheat the grill and use a stiff grill brush to clear residue after cooking. Avoid soaking or using harsh detergents that can damage the enamel and follow the recommended preheat routine to burn off stuck food before brushing.

• Preheat grill on high for 15 minutes before cleaning
• Brush clean with a grill brush after preheating
• Manual care: do not use dishwasher or abrasive chemicals
• Store dry to minimize long‑term moisture exposure

Why choose porcelain‑enameled cast‑iron over other grate materials?

Porcelain‑enameled cast iron blends the heat performance of cast iron with a protective enamel layer that improves durability and makes the surface easier to maintain. It offers a balance of professional searing capability and lower maintenance compared with bare cast iron.

• Better heat storage than stainless steel grates
• Enamel finish reduces rust and sticking compared with raw cast iron
• Robust weight and thickness for steady cooking temperatures
• Designed to replace original OEM grates for authentic performance

Who is this for? These replacement grates are ideal for owners of Weber Genesis 300 series grills (2007–2016) who want to restore original cooking performance and searing capability. They suit backyard cooks who value heavy‑duty heat retention and clear grill marks, and who are willing to follow manual care instructions (preheating and brushing) to preserve the porcelain enamel. If your grill is a Genesis II, Genesis II LX 300 series, or a post‑2022 Genesis model, select the matching grate specified for those platforms instead.
