QuliMetal 19.5in 9MM Grill Grates for Weber Genesis 300 Series - Heavy

In this review the QuliMetal 19.5in 9MM grill grates are evaluated for owners of Weber Genesis 300 Series grills who want a heavy-duty, low-maintenance replacement. The single biggest reason to buy is the thicker 9MM SUS304 stainless steel rods that deliver noticeably better heat retention and durability than typical 5MM or 7MM replacement grates. These grates are a direct-fit option for many Genesis 300 models and provide a substantial upgrade in solidity and cleaning ease for regular grillers.

Key Features

• Perfect Compatibility: Designed specifically for Weber Genesis 300 Series grills with front control knobs and selected Pit Boss PB700 Series units for a direct, worry-free fit.
• Precise Dimensions: Each grate measures 19.5in x 12.9in and two grates cover 19.5in x 25.8in, matching the cooking area of Genesis 300 grills.
• 9MM SUS304 Construction: Thick 9MM food-grade stainless steel rods resist rust and heat, offering greater long-term durability than thinner replacements.
• 18 Crossbars: More crossbars reduce food slippage and improve heat distribution compared with typical 15-crossbar designs.
• Low Maintenance: Smooth stainless finish cleans easily and resists flaking or chipping common to cast iron alternatives.
• Substantial Weight: At about 22.7 lb total, the grates keep heat and remain stable on the grill for consistent searing and cooking.

Who It's For

This product is aimed at owners of compatible Weber Genesis 300 Series models (including many E/EP and S variants from 2007 to 2016) who want a long-lasting, near-professional cooking surface that is easier to maintain than cast iron. Serious weekend cooks who value heat retention, sturdiness, and easy cleaning will appreciate the thicker SUS304 rods and denser crossbar layout.

These grates are not for owners of Weber Genesis II 300 or Genesis II LX 300 Series; those users should look for grates explicitly marked for the II series. Casual grillers who prefer the seasoning and nonstick properties of cast iron may still prefer cast iron grates despite the greater maintenance they require.

Pros & Cons

Pros

• Excellent fit for many Genesis 300 models, giving users confidence during installation and use.
• Thick 9MM SUS304 rods provide superior durability and heat retention compared with thinner alternatives.
• More crossbars and heavier build reduce food slipping and improve cooking stability and searing.
• Easy to clean stainless surface that resists flaking and rust for lower upkeep.

Cons

• Not compatible with Weber Genesis II 300 and Genesis II LX 300 Series, so verifying model fit is essential.
• Heavier weight can be cumbersome for some users when removing or handling grates during cleaning.

Frequently Asked Questions

Do these grates fit my Genesis 300 grill?
They are designed for many Weber Genesis 300 Series models with front control knobs and select Pit Boss PB700 Series units; verify your model year against the compatibility list before buying.

How do these compare to cast iron grates for maintenance?
The SUS304 stainless surface cleans more easily and will not flake or chip like cast iron, though cast iron can offer different searing characteristics if properly seasoned.
