QuliMetal 9mm 304 Stainless Steel Grill Grates for Weber Genesis II 300 — 18.75" Pair, Heavy-Duty Seared Searing & Heat Retention

These QuliMetal 9MM 304 stainless steel grill grates are heavy-duty replacement cooking grates sized for Weber Genesis II 300-series grills that deliver deeper sear marks, improved heat retention, and long-lasting corrosion resistance.

If your Weber Genesis II 300-series grates are warped, pitted, or simply not holding temperature like they used to, this pair of 18.75" x 13.25" grates (combined 18.75" x 26.5") offers a direct-fit, durable upgrade. Constructed from food-grade 304 stainless steel using solid 9mm rods, this set is engineered to resist rust, minimize sag under heavy food loads, and distribute heat more evenly for better grilling results.

How will the 9mm rod thickness change my grilling?

The 9mm solid steel rods are significantly thicker than standard 5mm–7mm options, which raises heat capacity and surface rigidity. Thicker rods hold more thermal mass, so they sear faster and maintain contact heat when you add cold food.

• 9mm solid rods for deeper, defined sear marks
• Greater heat retention means fewer temperature drops when adding food
• Stiffer structure resists sagging under heavy cuts or cast-iron pans

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

This QuliMetal set is designed specifically to replace Weber part numbers 66095 and 66802 and fits many Genesis II 300-series and compatible KitchenAid models. Measuring 18.75" x 13.25" per grate, they match the footprint of 2017-and-newer Genesis II 300, LX 300, and several sub-models listed below.

• Compatible with Genesis II E-310, S-310, SE-310, E-315, E-325, E-330 and more
• Also compatible with certain Genesis II LX and KitchenAid 720-0954 models
• Always verify your original grate dimensions before purchase

How durable and maintainable are these stainless grates?

Made from food-grade 304 stainless steel, the grates resist corrosion and high-heat deformation for long-term outdoor use. The smooth stainless finish reduces sticking and simplifies cleaning after each cook, and the heavy 19.85 lb build increases toughness compared with lighter aftermarket options.

• 304 stainless resists rust and corrosion for extended life
• Large mass (about 19.85 lbs) minimizes bending and warping
• Smooth surface eases scraping and washing after use

What cooking improvements can I expect with these grates?

Because they hold more heat and stay flat under pressure, these grates deliver more consistent searing and grill marks across the whole cooking surface. You’ll notice improved crust development on steaks and steadier temperatures for vegetables and thicker proteins.

• Better crust and sear on steaks, burgers, and chops
• More even temperature across the cooking surface
• Reduced hot-spot variability for repeatable results

Who is this for: These QuliMetal 9mm stainless grates suit backyard grillers who own a Weber Genesis II 300-series or compatible models and want a robust, longer-lasting replacement. They’re ideal for cooks who prioritize strong sear marks, stable heat retention during busy cooks, and low-maintenance materials that stand up to frequent outdoor use. If you need a trustworthy direct-fit replacement that increases grilling performance without modifying your grill, this set is tailored for you.
