Grill Parts for Weber Genesis 300 Series 19.5in Grill Grates - Durable

Our review of these 19.5in replacement grill grates finds them best suited for owners restoring or upgrading a Weber Genesis 300 series with front control knobs or an equivalent Pit Boss PB700. The single biggest reason to buy is the use of heavy-duty SUS304 food-grade stainless steel with 7mm solid rods and 18 cross bars, which gives a sturdier, longer-lasting cooking surface that resists corrosion and is easier to clean than coated cast iron. For anyone wanting near-original fit and improved maintenance, these grates deliver dependable value.

Key Features

• Compatibility: Fits Weber Genesis 300 series models with front control knobs including E-310, E-320 and E-330 model ranges and select part numbers, ensuring a correct replacement for those grills.
• Material: Made from SUS304 food-grade stainless steel for corrosion resistance and heat durability during frequent grilling.
• Rod Diameter: 7mm solid rod thickness gives greater rigidity and helps prevent bending or deformation under heavy pans or repeated use.
• Design: Each grate has 18 parallel bars instead of the usual 15, reducing the chance of food slipping through and improving sear consistency.
• Cleaning: Smooth stainless surface is easier to wipe or brush clean than porcelain-coated cast iron, lowering maintenance time between cooks.
• Weight and Build: Heavier overall construction than the original, which contributes to a substantial feel and long-term durability.

Who It's For

These grates are ideal for grill owners who need a robust replacement for Weber Genesis 300 series grills with front control knobs or those refurbishing an older E-310/E-320/E-330 grill. They suit people who prefer stainless steel over porcelain-coated cast iron for lower maintenance and who want a grate with thicker rods for durability and better searing.

They are not suitable for owners of Weber Genesis II 300 series or Genesis II LX 300 series models, so shoppers with those newer Genesis II variants should look for parts specifically listed for those grills instead.
