6 Best Alternatives to the Gcostar Cast Iron Grill Grates (2026)

How these alternatives compare

FORYEYC 3-Piece Cast Iron Grill Grates

The FORYEYC 3-Piece Cast Iron Grill Grates offer a complete 3-piece set, whereas the Gcostar provides a 2-piece narrow and 1-piece larger grate configuration. FORYEYC dimensions are listed as 17 by 24.5 inches total coverage, differing from the Gcostar’s 17 by 7 and 17 by 10.5 inch split. Both use cast iron for solid heat retention and classic searing marks. FORYEYC targets the same Char-Broil Performance 4-Burner grill, ensuring direct fit compatibility. You choose FORYEYC if you prefer a single unified grate set over the split layout of the Gcostar. The material quality remains comparable, focusing on durability and authentic grill performance for gas grill owners.

Hisencn 18" x 25" Cast Iron Grate and Heat Plate Kit

Hisencn provides an 18 by 25-inch cast iron grate and heat plate kit, designed for 5-burner Char-Broil Performance models. This contrasts with the Gcostar’s 4-burner specific 17 by 7 and 17 by 10.5 inch grates. Hisencn includes essential burner protection plates, a feature absent in the Gcostar product data. The Hisencn grate is slightly wider at 18 inches compared to the Gcostar’s 17-inch width. You should select Hisencn if your grill model requires a 5-burner setup or if you need burner guards to protect your gas lines. Both options utilize cast iron for robust cooking surfaces, but Hisencn offers a more comprehensive repair solution for larger grill configurations.

BBQration 18 3/16-Inch Cast Iron Grate

The BBQration 18 3/16-Inch Cast Iron Grate is intended for Big Green Egg Large units, not Char-Broil gas grills. It is a single, round grate measuring 19 inches in length and 10 inches in width. This differs significantly from the Gcostar’s rectangular 17 by 7 and 17 by 10.5 inch design. BBQration weighs 1 pound and features a matte finish, while Gcostar is black cast iron. You should only consider BBQration if you own a Kamado-style ceramic grill. It is not a compatible replacement for your Char-Broil Performance grill. This option serves kamado owners needing a durable, direct-fit grate for standard 18-inch charcoal grills, offering a completely different cooking environment than gas grates.

Kamado Joe Classic Reversible Cast Iron Griddle

Kamado Joe Classic Reversible Cast Iron Griddle is a half-moon shaped griddle for Kamado Joe grills. It measures 18.3 inches in length and 8.98 inches in width, weighing 7 pounds. This is a flat cooking surface, unlike the Gcostar’s slatted grill grate. The Kamado Joe product is designed for charcoal cooking, not gas grills. You should pick this if you want to add flat-top cooking capability to a ceramic grill. It is not compatible with your Char-Broil Performance 4-burner gas grill. The reversible design allows for searing on one side and griddling on the other. This option provides versatility for kamado owners but does not serve as a direct replacement for your existing gas grill grates.

Charbrofire 9.75-Inch Cast Iron Fire Grate

Charbrofire 9.75-Inch Cast Iron Fire Grate is a base charcoal grate for Kamado Joe Classic series grills. It measures 10 by 10 inches and weighs very little compared to cooking grates. This product is designed to catch ash and support charcoal, not to cook food directly. It is incompatible with your Char-Broil Performance gas grill. You should choose Charbrofire only if you need to replace the base grate in a Kamado Joe grill. The Gcostar grates are for cooking surfaces in gas grills. This distinction is critical, as the Charbrofire grate serves a foundational role in charcoal setups. It does not offer the same cooking functionality as the Gcostar cast iron grates.

Cmanzhi 18-Inch Cast Iron Grate and Griddle Set

Cmanzhi 18-Inch Cast Iron Grate and Griddle Set is a heavy-duty 15-pound set for Kamado Joe Classic and Big Green Egg Large grills. It includes both a grate and a griddle, offering versatile cooking options. This is significantly heavier and larger than the Gcostar’s 17-inch grates. The Cmanzhi product is designed for ceramic kamado grills, not gas grills. You should select this if you own a kamado and want to upgrade your cooking surface. It is not a compatible replacement for your Char-Broil Performance grill. The set provides flat-top cooking capability alongside traditional grilling. This option serves kamado owners seeking durability and versatility, differing entirely from the gas grill-specific Gcostar product.
