19.5 inch Grill Grates for Weber Genesis 300 Series - Cast Iron

In this review of the Paayox 19.5 in grill grates, the bottom line is simple: this is a practical, heavy-duty replacement set for owners of Weber Genesis 300 series grills who want solid heat retention and a near-original fit. The reviewer found these cast iron cooking grids best for people who value even searing and long heat hold, especially on Genesis E310/E320/E330 and S310/S320/S330 models. The package of two 19.5 in x 12.9 in pieces replaces the factory center grates and aims to deliver the look and cooking performance expected from original-style cast iron grids.

Key Features

• Exact size fit: Each piece measures 19.5 in x 12.9 in so they align with the Genesis 300 series grill openings for a secure fit.
• Cast iron heat retention: The cast iron material heats quickly and holds temperature to create even searing and stable cooking heat.
• Compatibility list: Designed for multiple Genesis 300 variants including E310, E320, E330 and S310, S320, S330 models for straightforward replacement.
• Two-piece set: The package includes two matching grates that together cover a 19.5 in x 25.8 in cooking area for balanced coverage.
• Durable finish: The grates are made to resist shedding after repeated heating cycles and maintain grilling performance over time.

Who It's For

This set is for owners of Weber Genesis 300 series grills who need a direct replacement for worn or damaged center grates and who prefer the sear and heat behavior of cast iron grids. It also fits some Pit Boss models and a broad list of factory Weber part numbers, making it suitable for users trying to restore even cooking across the main grill surface.

It is less appropriate for owners of grills outside the listed Genesis 300 family or for buyers who need porcelain-coated or stainless steel alternatives; those shoppers should verify dimensions and consider other materials if they require a different finish or lower maintenance.
