Upgrade Round Fire Pit Grate (The Easy Way) | Arteflame

Upgrade Your Round Fire Pit to a Pro-Grade Grill

You can instantly transform a standard brick, stone, or metal round fire pit into a professional wood-fired grill by installing a solid carbon steel cooktop. Unlike traditional wire grates that rust and lose heat, a heavy-duty carbon steel plancha insert creates distinct temperature zones, prevents flare-ups, and seasons over time to become naturally non-stick for a lifetime of cooking.

Why Choose a Carbon Steel Plancha Over Wire Grates?

Most fire pits come with cheap wire grates that warp under high heat and allow food to fall into the fire. Upgrading to a solid carbon steel surface changes the physics of how you cook. The solid metal conducts heat laterally, allowing you to sear steaks at high temperatures near the center while simultaneously roasting vegetables gently near the outer edge.

Pro Tip: Because carbon steel heats evenly, you get the "Maillard reaction" across the entire surface of your meat, resulting in a steakhouse-quality crust that wire grates simply cannot achieve.

Below is a comparison of why enthusiasts are switching from wire to solid steel:

How Do I Know Which Replacement Grate Fits?

Finding the right fit for a round fire pit grate upgrade is easier than it looks. You generally do not need a custom build. Most circular fire pits fall into standard sizing categories. Focus on the outer diameter of your pit.

• Measure the Opening: Measure the interior width of your fire pit.
• Check Support: Ensure your pit has a ledge or sufficient rim width to hold the steel plate heavy weight (often 50+ lbs).
• Choose the Size: Select a grate that covers the opening entirely or sits flush inside, depending on your pit's design.

Common Sizes for Upgrades

Arteflame and similar manufacturers typically offer inserts in standard sizes like 20", 30", and 40". If your fire pit is a non-standard size (e.g., 34"), you generally buy the next size up to ensure the plate rests securely on the rim without falling in.

What Are the Benefits of the Center Opening?

You will notice top-tier fire pit grill grates, like the Arteflame, feature an open center. This isn't just for aesthetics; it is crucial for airflow and fuel management.

The center hole creates a chimney effect, drawing air in to feed the fire efficiently. It also allows you to add wood logs or charcoal without lifting the hot cooking surface. For those who want direct flame contact, you can often add a "grill grate riser" into this center hole to get flame-kissed sear marks on your burgers or steaks.

Pro Tip: Use the temperature gradient to your advantage. The ring is hottest near the center (600°F+) and cools as you move outward (300°F). Sear your protein in the middle, then slide it to the outer edge to finish cooking internally without burning the exterior.

How Do You Maintain a Carbon Steel Grate?

Maintenance for a carbon steel grate is identical to caring for a cast iron skillet. It requires seasoning with oil to prevent rust and maintain its non-stick properties.

1. Initial Seasoning: Coat the cooktop with a high-smoke-point oil (like grapeseed or flaxseed oil) and heat it until the oil polymerizes, turning the steel black.
2. Routine Cleaning: After cooking, scrape food residue into the fire while the plate is still warm. wipe it down with a lightly oiled cloth.
3. Winter Storage: If you leave it outside year-round, keep a light coat of oil on it. The steel is thick enough to withstand winter, but oil prevents surface oxidation.

Frequently Asked Questions

Can I leave my carbon steel fire pit grate outside all year?

Yes, carbon steel is extremely durable and designed for outdoor use. However, you should keep it seasoned with a thin layer of oil to prevent surface rust, or cover it when not in use for extended periods.

What type of wood is best for cooking on a fire pit?

Hardwoods like oak, hickory, maple, or pecan are best for cooking because they burn hot and clean. Avoid softwoods like pine, as they produce resinous smoke that can impart an acrid flavor to your food.

How long does it take to heat up the cooktop?

Generally, allow your fire to burn for 20 to 30 minutes before cooking. This ensures the carbon steel plate has absorbed enough heat to sear meat effectively and that the fire has established a bed of hot coals.
