How do these cast iron grates change cooking performance?

Cast iron retains and distributes heat more steadily than thin steel, producing consistent searing and deeper caramelization. These grates help create defined grill marks, reduce hot-spot variability, and maintain cooking temperatures when you sear or grill over medium-high heat.

• Improved heat retention for even browning and searing
• Matte cast-iron surface produces stronger grill marks
• Thicker bars reduce heat loss when opening the lid
• Durable under repeated heating and cooling cycles when maintained properly

What maintenance and seasoning do these grates need?

Cast iron performs best when kept rust-free and lightly seasoned. After the first few uses, coat the bars with a thin layer of cooking oil and heat to build a protective patina; clean with a grill brush and avoid soap or long water exposure.

• Season with high-smoke-point oil after cleaning and drying
• Scrape with a nylon or brass brush; avoid steel wool that strips seasoning
• Store in a dry place or indoors during long off-seasons to prevent rust
• Re-season periodically if food begins to stick or metal looks dull

How easy is installation and what does the package include?

Installation is straightforward: remove your old grates and drop in the matched pair; no tools are typically required if your grill accepts the same mounting points. The package includes one larger and one narrow cast iron grate to match the original two-piece layout.

• Package contains two cast-iron grates: 18 1/8" x 9 5/16" and 18 1/8" x 6 1/2"
• Matte cast-iron construction for durability and heat control
• Direct replacements for multiple Char-Broil part numbers listed on the product page
• Simple drop-in swap for compatible Performance 2-burner grills
