QuliMetal Grill Parts Replacement for Weber Genesis 300 Series

In this review of the QuliMetal Grill Parts Replacement for Weber Genesis 300 Series, the bottom line is simple: this set is aimed at owners of Weber Genesis 300 grills with front-mounted control knobs who want heavier, long-lasting cast iron grates and reliable porcelain-steel flavorizer bars and heat deflectors. The single biggest reason to buy is durability - the cast iron grates are noticeably heavier and thicker than stock, offering better heat retention and a flatter cooking surface that reduces food falling through. For anyone replacing worn grates or seeking improved heat distribution, this set makes a clear, practical upgrade.

Key Features

• Perfect compatibility: Designed specifically for Weber Genesis 300 series models with front-mounted control knobs, replacing the common Weber grate and flavorizer part numbers for a direct fit.
• Cast iron grates: Two heavy cast iron grates provide better heat retention and a flatter slat profile that helps prevent food from dropping into the burners.
• Porcelain-steel flavorizer bars: Five porcelain-steel flavorizer bars create classic barbecue vaporization and protect burners from drips while adding smoky flavor.
• Porcelain heat deflectors: Two porcelain-steel heat deflectors shield the burners and promote more even heating across the cooking area.
• Enhanced thickness: Built at a 16GA thickness for added strength compared with many thinner aftermarket options, improving longevity and burner protection.
• Snow point coating: A high-temp resistant surface finish helps prevent premature coating failure and reduces the risk of off flavors from coating degradation.

Who It's For

This kit is best for owners of Weber Genesis E-310, E-320, E-330, S-310, S-320, S-330 and EP/CEP-310/330 who need a robust replacement for worn or damaged grates and flavorizer bars. It suits backyard grillers who prioritize longevity, heat retention and a flatter grate surface for easier grilling and cleaning.

It is not appropriate for owners of the Genesis II 300 series, Genesis II LX 300 series, or any Genesis 300 model with side control knobs - those variants have different part shapes and sizes and will not fit this set.

Pros & Cons

Pros

• Sturdy cast iron grates with superior heat retention and a flatter slat design that prevents food loss.

• 16GA construction and porcelain-steel parts add durability and resistance to chipping compared with thinner aftermarket pieces.

Cons

Frequently Asked Questions

Will these parts fit my Genesis 300?
They fit Genesis 300 series grills with front-mounted control knobs such as E-310, E-320, E-330 and related S and EP models; they do not fit Genesis II 300 or models with side control knobs.

Are the grates non-stick?
Cast iron grates offer excellent non-stick performance when maintained and oiled after each use, which customers report helps with cleaning and food release.

Do the flavorizer bars add real smoke flavor?
The porcelain-steel flavorizer bars vaporize drippings to create barbecue flavor while protecting the burners, producing the expected smoky taste.
