BBQ-PLUS Cast-Iron Cooking Grates Replacement for CharBroil & Nexgrill — 17-1/16 x 9-1/2 in Set of 3, Heavy Matte for Even Heat

These three 17-1/16" x 9-1/2" cast-iron cooking grates replace original CharBroil and compatible Nexgrill infrared grill grids to restore even heat and crisp sear marks.

If your CharBroil or compatible gas grill has a warped, rusted or missing grate, these heavy matte cast-iron replacements from BBQ-PLUS are sized to match multiple infrared 3–4 burner models. Sold as a set of three, the pieces fit the specified CharBroil and Nexgrill part numbers and offer excellent heat retention for consistent cooking across the whole surface. The grates arrive unseasoned and benefit from routine cleaning and seasoning to extend their service life.

Will these grates fit my CharBroil or Nexgrill infrared model?

These replacement grids are manufactured to the dimensions and mounting pattern used on many CharBroil Signature and Performance infrared models, as well as several Nexgrill and retailer-branded units. Check your grill’s part number against the compatible list and measure the cooking area before ordering.

• Individual grate size: 17-1/16" x 9-1/2".
• Total assembled span (3pcs): 17-1/16" x 28-1/2".
• Compatible with CharBroil and Nexgrill model numbers and certain retailer SKUs.

How does cast iron improve grilling performance?

Cast iron holds and spreads heat more evenly than thin steel, stabilizing surface temperature when you add cold food. That steady heat helps create crisp, professional-looking sear marks and better caramelization without hot spots across the cooking area.

• Superior heat retention for even cooking.
• Produces clear sear lines that enhance flavor perception.
• Durable composition withstands repeated use when properly maintained.

What maintenance do these cooking grates require?

Cast-iron grates need regular scraping and occasional seasoning to prevent rust and keep food from sticking. After each cook, scrape off residue while the grate is warm; periodically apply a thin oil coating and heat the grill to polymerize the oil into a protective layer.

• Scrape while warm to remove stuck-on debris.
• Season with high-smoke-point oil after cleaning to build protection.
• Store dry and avoid prolonged exposure to rain or humidity.

What comes in the box and what should I expect at installation?

The package contains three cast-iron grates sized to span your grill’s cooking area when placed side-by-side. No additional hardware is required; simply remove the old grates and set the replacements in the same notches. Verify alignment before first use to ensure stable contact with burner covers and heat distribution plates.

• Set of 3 BBQ-PLUS cast-iron grates.
• Ready to position — no bolts or adapters included.
• Inspect fit and confirm stable seating before heating.

Who is this for? Grillers who own compatible CharBroil Signature, Performance, or specified Nexgrill/retailer models and want a durable, heat-retaining replacement grate will find this set ideal. Choose these BBQ-PLUS cast iron grates if you need restored searing performance, a dependable cooking surface for frequent use, and parts that match the original dimensions for easy, no-fuss installation. If you prefer low-maintenance stainless alternatives, these cast-iron grates require occasional seasoning but reward you with superior sears and longevity when cared for properly.
