How to choose the best grill grates
Choosing the right replacement grate starts with knowing your grill’s exact model and the size of the old grates. Always measure your existing grates and check the manufacturer’s compatibility list before buying. The material is the next major decision, as it affects cooking performance, maintenance, and durability.
What to look for
- Material: Cast iron retains heat excellently for searing but requires seasoning and care to prevent rust. Porcelain-coated cast iron adds a easy-clean layer but the coating can chip. Stainless steel is durable and low-maintenance but may not hold heat as well.
- Precise Fit: Grates must sit securely on your grill’s firebox. Check the listed length, width, and any model-specific cutouts or leg positions.
- Maintenance: Consider how much effort you want to invest. Bare cast iron needs regular oiling, while enameled or stainless steel options are simpler to clean. Always follow the manufacturer’s care instructions.

FAQ
How do I know if a replacement grate will fit my grill?
The safest method is to measure your existing grates (length, width, and thickness) and compare them to the product’s listed dimensions. Also, check the manufacturer’s compatibility list for your grill’s specific make and model number, which is often found on a rating plate on the grill body.
What’s the difference between cast iron and stainless steel grill grates?
Cast iron is prized for its superior heat retention and ability to create a strong sear, but it requires seasoning to maintain a non-stick surface and prevent rust. Stainless steel is more corrosion-resistant, generally easier to clean, and doesn’t require seasoning, but it may not get quite as hot or hold heat as evenly as cast iron.
Can I put my grill grates in the dishwasher?
It depends on the material. Porcelain-enameled or stainless steel grates are sometimes dishwasher safe, but cast iron never is. Always check the manufacturer’s cleaning instructions. Washing cast iron in a dishwasher will strip its seasoning and cause rust.
Why are some grates sold in packs of two or three?
Most gas grills have a cooking surface made of multiple grate sections that sit side-by-side. A pack of two or three grates is designed to replace the entire cooking surface of a 2, 3, or 4-burner grill, respectively. Always check how many grates your specific grill uses.
