Uniflasy 18-Inch Cast Iron Grill Grates — 4-Piece Direct-Fit for Char-Broil 6-Burner, Heavy-Duty Sear

These Uniflasy 18-inch heavy-duty cast iron grill grates replace the original Char-Broil Performance 6-burner grates to restore even heat, professional sear marks, and long-lasting durability.

If your Char-Broil Performance 6-burner grill (models like 463244819, 463276517, 463245917, 463276617 and related numbers) has worn or broken cooking grates, this four-piece set from Uniflasy offers a direct-fit replacement made from upgraded cast iron. The set includes three larger grates and one smaller piece sized to match the factory layout, delivering the same coverage and mounting points as the original parts so you can resume grilling quickly.

How do these cast iron grates improve cooking performance?

Upgraded heavy-duty cast iron balances heat retention and distribution for steadier cooking and stronger sear marks compared with thin or warped factory grates. The weight and thermal mass help maintain steady temperatures when you add food, and the dense material produces clearer char lines for a more professional appearance.

• Thicker cast iron preserves heat for consistent cooking across the surface.
• Produces defined sear marks to enhance appearance and Maillard flavor.
• Less brittle alloy reduces breakage risk during handling or thermal cycling.
• Improved corrosion resistance compared to lower-grade cast grates.

What maintenance is required to keep these grates rust-free and non-stick?

Cast iron grates need simple, regular upkeep: scrape clean after each use, season with oil, and keep them dry when stored. These practices limit surface oxidation, maintain a natural non-stick patina, and extend the life of your grates without harsh chemicals.

• Scrape food residue after every cook and wash with soapy water if needed.
• Dry thoroughly and season by brushing a thin layer of cooking oil on the surface.
• Leave grill dampers ajar and cover the grill to prevent trapped condensation.
• For long-term storage, heavily oil and wrap grates in plastic inside a covered grill.

How simple is installation and are replacement parts included?

Installation is straightforward: lift out the old grates and set the Uniflasy pieces into the same mounting slots. No tools are required if your grill originally used removable grates; the set mirrors the original sizes so placement is intuitive.

• Plug-and-play replacement for original factory grate positions.
• Set includes three larger grates and one smaller grate to match the original arrangement.
• No extra hardware required—use existing grate supports and brackets.

Who is this for? Home grillers and backyard chefs who own compatible Char-Broil Performance grills and want a durable, professional-quality replacement will appreciate these Uniflasy cast iron grates. They suit anyone replacing warped or damaged factory grates, seeking better heat retention and sear results, or preparing a grill for season-long reliability with straightforward maintenance.
