Grill Grates for Charbroil Performance 18in x 25in - Heavy Cast Iron

In this review the focus is on replacement cast iron grill grates designed for a wide range of Charbroil Performance grills. The bottom line: these 18in x 25in grates are for grill owners who want the heat retention and searing performance of cast iron without paying for an OEM part. They work well as a direct fit for many 4-, 5- and 6-burner Charbroil models and provide the bold sear marks and durable surface more experienced home cooks expect from cast iron grates.

Key Features

• Dimensions: The full cooking surface measures 18in x 25in, giving clear guidance on fit and coverage for compatible Charbroil models.
• Material: Made from matte cast iron, these grates retain heat well and deliver consistent searing across the cooking surface.
• Model compatibility: Listed to replace original models such as G470-0003-W1 and G470-0002-W1, so buyers can match them to their existing grate layout.
• Durability: Cast iron construction is more resistant to chipping than enamel finishes and stands up to regular use when maintained properly.
• Cleaning and care: The included basic cleaning steps-high heat burn-off, scraping, seasoning and oiling for storage-make maintenance straightforward.
• Versatility: Compatible with a long list of Charbroil Performance 2-, 4-, 5- and 6-burner models, which simplifies replacement across model years.

Who It's For

These grates are best for Charbroil owners who want a heavy-duty replacement that reproduces the heat retention and sear of cast iron, particularly people who grill steaks, vegetables and thicker cuts that benefit from even high heat. A buyer who values a long-lasting surface and the ability to re-season the grates will appreciate this offering.

Not every shopper should choose these grates: those who prefer enamel-coated grates for low-maintenance rust protection or who need a precise OEM multi-piece set should double-check model compatibility and consider alternatives if they require factory-finished coatings.
