QuliMetal Cast Iron Grill Grates for Weber Genesis II 300 Series — 18.75" Pair, Pre-Seasoned Heavy-Duty

The QuliMetal 18.75" cast iron grill grates are heavy-duty replacement cooking grates engineered to fit Weber Genesis II 300 Series and select KitchenAid models for improved heat retention and searing performance.

Upgrade your grill with a pair of pre‑seasoned cast iron grates sized to match many Genesis II 300 Series configurations. These two grates (each 18.75" x 13.25", combined 18.75" x 26.5") are designed as direct replacements for several Weber part numbers and offer thicker, denser construction than common aftermarket options. That construction helps deliver steady heat, better sear lines and a cooking surface with smaller gaps to keep food from falling through.

Will these grates fit my Weber Genesis II 300 Series grill?

Yes — the QuliMetal set is cut to fit many Genesis II 300 models from 2017 onward. Check your model designation against the compatible list to confirm fit before ordering.

• Compatible with Genesis II E-310, S-310, SE-310 and other listed 300 Series models.
• Replaces Weber part numbers 66095 and 66802 and several GS4 accessory numbers.
• Also fits certain KitchenAid models (720-0954 / 720-0954A).

How does cast iron affect grilling results?

Cast iron's density holds and distributes heat more evenly than thin steel grates, which helps with consistent searing and stable cooking temperature across the surface. The thicker bars produce pronounced sear marks while the flatter tops and tighter spacing provide more meat-to-grate contact and reduce food loss through the grate.

• Heavier mass (about 15.07 lb for the set) increases heat retention.
• Flat-top bars yield stronger sear marks and improved crust development.
• Smaller gaps prevent small items from falling through.

What maintenance do these pre-seasoned grates need?

They arrive pre-seasoned to reduce initial sticking and improve food release, but regular upkeep keeps them performing and prevents rust. Light cleaning after each use and occasional re-seasoning will extend the grates' life and maintain their nonstick characteristics.

• Wipe or brush away residue after grilling, avoid harsh detergents.
• Dry thoroughly and apply a thin coat of cooking oil before storage.
• Re-season on the grill periodically by heating with oil to build a protective layer.

How do I verify dimensions and weight for my setup?

Each grate measures 18.75" x 13.25", combining to a full span of 18.75" x 26.5"; the set weighs about 15.07 pounds. Compare these measurements to your existing grate or your grill's specifications to ensure a correct fit and to account for the heavier weight during installation.

• Individual grate: 18.75" x 13.25"; combined: 18.75" x 26.5".
• Set weight: approximately 15.07 lb — heavier than many alternatives.
• Measure your grill opening and confirm model number for compatibility.

Who is this for: The QuliMetal 18.75" cast iron grates suit backyard chefs and grill owners with compatible Weber Genesis II 300 Series or listed KitchenAid models who want better heat retention, stronger sear marks and a more durable cooking surface than stock or lightweight aftermarket grates. They’re a practical upgrade for anyone prioritizing even cooking and reduced food flare‑through while remaining straightforward to maintain with routine seasoning and care.
