QuliMetal 18.75ft Grill Grates for Weber Genesis II 300 Series - Heavy

In this review the QuliMetal 18.75' Grill Grates are presented as a direct replacement for a range of Genesis II models; they are aimed at owners who want a durable, long-lasting cooking surface with improved searing. The bottom line: these porcelain-enameled cast iron grates are best for Genesis II 300 and LX 300 owners who need heavier, corrosion-resistant replacements that fit models listed from 2017 and newer. The single biggest reason to buy is the combination of strong heat retention and a glossy finish that reduces sticking and simplifies cleaning.

Key Features

• Exact fit: Designed to replace factory grates for multiple Genesis II 300 and LX 300 models, giving a hassle-free swap for compatible grills.
• Premium material: Built from porcelain-enameled cast iron for even heat distribution and strong resistance to corrosion.
• Improved searing: Flat, wide slats and smaller gaps deliver clear sear marks and keep food stable while grilling.
• Ready to use: Pre-seasoned surface offers good food release out of the box, reducing the break-in time before regular use.
• Easy maintenance: The glossy enamel wipes clean or soaks free of residue, cutting time spent on post-cook cleanup.
• Sturdy build: Heavier construction improves stability and heat retention compared with lighter grate options.

Who It's For

These grates are ideal for owners of Weber Genesis II 300 Series and Genesis II LX 300 Series grills (models listed for 2017 and newer) who want a heavy-duty, porcelain-enameled cast iron replacement that sears well and resists corrosion. They suit weekend grillers and frequent hosts who value even heat and a grate that makes the grill look refreshed.

They are less suitable for users who need non-enameled stainless steel grates or those who prefer very lightweight, travel-friendly options; also confirm your exact model and year before buying to avoid compatibility issues.

Pros & Cons

Cons

• Heavier weight means they are less convenient to lift and handle than lighter grate alternatives.
