Custom Grill Grates vs. Inserts (The Truth) | Arteflame

The Bottom Line: Grates vs. Griddle Inserts

When upgrading a kettle grill, custom grill grates primarily offer aesthetic sear marks and slightly better durability than stock wire racks. However, an Arteflame carbon steel insert completely transforms the functionality of the grill, converting it into a wood-fired plancha and griddle. For versatility, smoke elimination, and restaurant-quality searing (Maillard reaction), a solid carbon steel insert creates a superior cooking surface compared to traditional open bars.

Which Upgrade Offers Better Performance: Custom Grates or Griddle Inserts?

Most grill owners look for aftermarket upgrades to replace rusting wire racks or to achieve better heat retention. While heavy-duty stainless steel or cast iron grates are popular, they still limit you to direct-fire cooking. This means you are constantly battling flare-ups and losing small vegetables or delicate meats through the gaps.

The Arteflame replacement insert changes the physics of your kettle grill. By using a solid carbon steel surface, the heat is distributed evenly across distinct temperature zones. You get high-heat searing in the center and moderate temperatures on the outer ring, allowing you to cook steaks, eggs, bacon, and vegetables simultaneously without a single flare-up.

Use this data to decide which upgrade fits your cooking style.

Why is Carbon Steel Superior for Searing?

A common misconception is that diamond-pattern grill marks equal flavor. In reality, flavor comes from the Maillard reaction—the browning of proteins. Traditional grates only brown the meat where it touches the metal, leaving the rest of the surface gray or pale.

A carbon steel griddle insert provides 100% surface contact. This creates a deep, edge-to-edge crust on steaks and burgers, locking in juices more effectively than open grates. Carbon steel also heats up faster than cast iron and is more responsive to temperature changes, making it ideal for the variable heat of a wood or charcoal fire.

Pro Tip: When using a solid insert, utilize the center opening as a "heat engine." Push your coals or wood directly under the center for temperatures exceeding 1,000°F, perfect for finishing a reverse-seared steak.

Does a Solid Insert Eliminate Grill Maintenance?

Cleaning wire grates often involves stiff brushes and burning off residue, which can lead to metal bristles ending up in food. Custom grates with complex shapes can be even harder to clean between the bars.

The Arteflame insert utilizes the same seasoning logic as a cast-iron skillet. Because it is a flat, solid piece of steel, cleaning takes seconds. You simply scrape the residue into the fire in the center, wipe it down with a rag and a little oil, and you are done. The surface improves with every use as the seasoning layer builds up.

Pro Tip: Never use soap on your carbon steel insert. After cooking, while the grill is still warm, pour a small amount of water on the surface and scrape it clean. Apply a thin coat of cooking oil to protect the seasoning against rust.

Frequently Asked Questions

Do Arteflame inserts fit standard Weber Kettle grills?

Yes, the inserts are precision-engineered to replace the standard grates on 22-inch and 26-inch round kettle grills, including Weber and other major brands. You simply remove the old grate and drop the insert in.

Is the smoke flavor lost when using a griddle insert?

No, the smoke flavor is actually enhanced. The open center allows wood smoke to circulate over the food while the solid steel prevents the acrid taste of burning grease caused by flare-ups.

Can I leave the insert outside year-round?

Yes, carbon steel is incredibly durable. As long as the insert is kept oiled (seasoned), it can withstand outdoor elements without rusting through, similar to a high-quality smoker or fire pit.
