How these grates compare
Kamado Joe Classic Reversible Cast Iron Griddle
The Kamado Joe Reversible Griddle offers dual cooking surfaces, unlike the Cmanzhi set which provides separate grate and plate pieces. It measures 18.3 inches by 8.98 inches and weighs 7 pounds, making it significantly lighter than the 15-pound Cmanzhi unit. The cast iron construction is similar, but the reversible design allows you to cook different foods simultaneously. It fits Kamado Joe Classic and Large Big Green Egg grills. You should choose this if you prefer a single, versatile surface over two distinct components. The thinner profile at 0.94 inches may retain less heat than the thicker Cmanzhi grate.
BBQration 18 3/16-Inch Cast Iron Grate
The BBQration grate is a single-piece replacement measuring 19 inches by 10 inches. It is much lighter at 1 pound compared to the 15-pound Cmanzhi set. This model is designed for standard kamado grills and focuses on durability rather than multi-surface versatility. You lose the included griddle plate and the heavy-duty feel of the Cmanzhi option. However, the matte cast iron finish provides reliable heat retention for direct grilling. It is a straightforward choice if you only need a grate replacement. The dimensions are slightly larger, so verify your grill interior before purchasing. It suits users prioritizing weight savings and basic functionality.
Charbrofire 9.75-Inch Cast Iron Fire Grate
The Charbrofire grate is a fire grate, not a cooking surface. It measures 10 inches by 10 inches and sits in the charcoal base of Kamado Joe Classic series grills. This is fundamentally different from the Cmanzhi cooking grate and griddle set. You cannot cook food directly on this piece. It is designed to catch ash and support charcoal. Choose this if your original fire grate is worn out and you need to restore proper airflow. It does not replace the cooking grate. The cast iron material is similar, but the application is entirely different. This is a base component, not an upgrade for your cooking surface.
Terefour 18-Inch Cast Iron Grate and Griddle Set
The Terefour set is a reversible cast iron griddle measuring 19 inches by 9 inches. It weighs less than the Cmanzhi set and offers a reversible design for cooking eggs and steaks on the same surface. The Cmanzhi option provides a separate grate and plate. The Terefour unit fits 18-inch ceramic grills well. It is a practical choice if you want versatility in a single piece. The height is 0.24 inches, which is thinner than the Cmanzhi grate. You give up the dedicated cooking grate but gain a multi-use surface. It is a good alternative for users who prefer flipping food or cooking different items on one plate.
Oklagarden 9.75-Inch Cast Iron Fire Grate
The Oklagarden grate is a fire grate for Kamado Joe 18-inch grills. It replaces the charcoal base, not the cooking surface. This is not a substitute for the Cmanzhi grate and griddle set. You need this if your fire grate is damaged. It is made of cast iron and fits models like KJ23RH and KJ23RHC. The dimensions are not fully specified in the data, but it is designed for the base. Do not buy this if you need a cooking surface. It is a functional replacement for the bottom of the grill. It does not offer any cooking versatility. It is strictly for maintaining the charcoal bed and airflow.
Grillflame 9.75-Inch Cast Iron Fire Grate
The Grillflame grate is a 9.75-inch fire grate for Kamado Joe Classic 18-inch grills. It replaces the charcoal base to restore airflow and heat distribution. This is not a cooking grate. The Cmanzhi set is for cooking food. The Grillflame unit is made of cast iron and fits models like KJ23RH and KJ23RHC. It is a precise replacement for the firebox base. You should pick this if your original fire grate is worn. It does not provide a cooking surface. It is essential for proper grill operation but does not replace the grate or griddle. It is a structural component, not a cooking accessory.
