Hongso Cast Iron Plate Setter for Large 18in Kamado Grills - Even Heat

In this review of the Hongso Cast Iron Plate Setter, the conclusion is straightforward: it is a practical heat deflector for owners of large 18in kamado grills who want consistent indirect heat and solid heat retention. The plate setter's cast iron construction and three-leg design make it a simple way to convert a grill into a reliable pizza stone or heat deflector, keeping food flavorful while producing good grill marks. It is best for cooks who prioritize durability and even cooking over ultra-precise fitment quirks.

Key Features

• Applicable Model: Fits large Big Green Egg and most other 18in kamado grills, providing a direct replacement for similarly sized parts.
• Material & Size: Made from high-density cast iron at 18in diameter and 2.5in height, the plate setter delivers strong thermal mass for steady temperatures.
• Three-Legged Design: The integrated 3 legs improve bearing capacity and stability so the stone sits solidly in the firebox during cooking.
• Even Heat Distribution: The cast iron spreads heat across the entire surface so pizzas, roasts, or ribs cook more evenly and retain original flavors.
• Easy to Maintain: Cleaning is simple: soak in hot water with detergent and scrub with a soft brush, then air-dry and store to protect seasoning.
• Longevity: The heat deflector complies with material standards and is intended to extend the life of a pizza stone or grill insert through robust construction.

Who It's For

The Hongso plate setter suits kamado owners with an 18in cooking diameter who want a heavy-duty, cast iron heat deflector that doubles as a pizza grilling stone. It appeals to backyard cooks who value heat retention and want predictable, evenly cooked pizzas, roasts, or low-and-slow dishes.

Those who should look elsewhere are users with nonstandard or slightly different internal dimensions; some buyers reported fit inconsistencies, so anyone with tight tolerance racks or unconventional grate arrangements should measure carefully before ordering.
