QuliMetal 18.75 in 9MM Grill Grates for Weber Genesis II - Heavy-Duty

In this review the QuliMetal 18.75 in 9MM grill grates are evaluated as a direct, heavy-duty replacement for a range of Weber Genesis II 300 series models. The bottom line: these grates are for owners who want long-lasting, food-grade 304 stainless steel cooking surfaces that resist corrosion and make cleaning easier. They stand out because of their thick 9MM rods and substantial weight, which deliver even heat contact and an improved sear compared with thinner stainless or porcelainized cast iron alternatives.

Key Features

• Exact fit for Genesis II 300 series: Designed to replace Weber part numbers 66095 and 66802 and fit many Genesis II E, S, SE and LX 300 models for drop-in installation.
• Food-grade 304 stainless steel: The SUS304 material offers excellent anti-corrosion properties so the grates remain rust-free through frequent use.
• 9MM solid rods: Thicker rods provide a sturdy cooking surface that tolerates high-intensity grilling and resists deformation over time.
• Improved sear and heat transfer: The heavy grid structure gives fuller contact with steaks and other foods to develop richer char marks and more even cooking.
• Easy to clean finish: Smooth 304 stainless resists food adhesion and wipes clean faster than porous or flaking surfaces.

Who It's For

These grates are best for grill owners who use their Weber Genesis II frequently and want a durable, long-lived upgrade that improves searing and is easy to maintain. The heavy construction suits people who value build quality and expect grates to endure years of regular barbecues without rusting or flaking.

Those who should look elsewhere include owners of older or non-compatible grill models - the size and model list should be confirmed before purchase - and buyers who prefer the heat retention characteristics or aesthetics of cast iron over stainless steel.

Pros & Cons

Pros

• Thick 9MM SUS304 rods create a robust, long-lasting cooking surface that resists bending.
• Matches multiple Genesis II 300 series and LX 300 models for a straightforward replacement.
• Food-grade stainless steel cleans easily and stays corrosion-resistant under heavy use.

Cons

• Heavier than typical grates, which is excellent for durability but may be more cumbersome to lift and handle.
