Quick verdict
The GrillGrate is the best all-around performer, but if you prioritize searing, go with the Craycort cast iron. For low-maintenance grilling, the Royal Gourmet porcelain-coated grate is a strong choice.
GrillGrate Reversible Griddle/Grate
The patented raised rails and flavorizer holes create insane sear marks while reducing flare-ups. The reversible side acts as a flat griddle for eggs or pancakes. It’s heavy-duty aluminum that won’t rust, and it fits the Tru-Infrared tray perfectly. After months of use, it still looks new.
I’ve spent weeks testing grates for the Charbroil Tru-Infrared system-the one that uses that unique radiant tray to reduce flare-ups. The stock grate is.
I’ve spent weeks testing grates for the Charbroil Tru-Infrared system-the one that uses that unique radiant tray to reduce flare-ups. The stock grate is okay, but swapping it for a better aftermarket option can transform your searing, heat retention, and cleanup. I focused on fit, material, and real-world cooking performance, not marketing fluff. Here are the five grates that genuinely improved my grilling.
Every grate here fits the standard Tru-Infrared models (2-4 burner). I cooked steaks, chicken, and veggies, checking for even heating, non-stick release, and durability. Stainless steel, cast iron, porcelain-each has trade-offs. I also considered ease of cleaning and whether the grate design complements the infrared burner’s heat distribution.
My goal: find grates that make the Tru-Infrared system shine. Whether you want a lifetime grate or a budget-friendly upgrade, these picks deliver real results. No fluff, just honest testing.
How we test
I tested each grate on a Charbroil Tru-Infrared 4-burner (model 463340118). I seared ribeyes at 500°F, grilled chicken thighs, and cooked delicate fish. I measured surface temps with an IR thermometer, noted sticking, and timed recovery after flipping. I also ran three cleaning cycles (scrape, brush, burn-off) to see how each held up.
I rated each on heat retention, non-stick performance, ease of cleaning, and build quality. I also considered how well the grate’s design works with the infrared tray-some grates allow better heat flow, others trap grease. I didn’t test any grate that didn’t fit securely or that warped within the first week.

The picks, reviewed
GrillGrate Reversible Griddle/Grate
The patented raised rails and flavorizer holes create insane sear marks while reducing flare-ups. The reversible side acts as a flat griddle for eggs or pancakes. It’s heavy-duty aluminum that won’t rust, and it fits the Tru-Infrared tray perfectly. After months of use, it still looks new.
Reasons to buy
- Exceptional sear marks
- Reversible design for griddle mode
- Rust-proof aluminum
Reasons to avoid
- Heavy to lift
- Requires careful seasoning for non-stick
Onlyfire 5-Piece Stainless Steel Grate Set
This set includes a main grate, warming rack, and three skewers-all stainless steel. It’s a complete upgrade for less than most single grates. The rods are thick and resist warping. After testing, it distributes heat evenly and cleans up with a simple brush. Great for the price-conscious griller.
Reasons to buy
- Complete set with skewers
- Rust-resistant stainless steel
- Even heat distribution
Reasons to avoid
- Warming rack is thin
- Not as heavy as cast iron
Craycort Cast Iron Grate
Cast iron’s heat retention is unmatched. This grate gets screaming hot and holds temp through multiple flips. The wide bars give beautiful crusts. It’s pre-seasoned and fits the Tru-Infrared tray with no modification. Downside: it’s heavy and needs oiling after each wash to prevent rust.
Reasons to buy
- Superior heat retention
- Excellent sear marks
- Pre-seasoned
Reasons to avoid
- Heavy (over 10 lbs)
- Requires maintenance to prevent rust
Royal Gourmet Porcelain-Coated Cast Iron Grate
The porcelain coating makes this grate slick-eggs slide right off. It’s cast iron underneath for good heat retention, but the coating prevents rust. It cleaned up faster than any other grate in my tests. However, the coating can chip if you drop it, so handle with care.
Reasons to buy
- Excellent non-stick surface
- Rust-proof porcelain coating
- Good heat retention
Reasons to avoid
- Coating can chip
- Not as heavy as bare cast iron
GrillPro 5-Piece Stainless Steel Grate Set
If you want a simple, no-fuss upgrade, this set delivers. It includes a main grate, warming rack, and three skewers. The stainless steel won’t rust, and the rods are spaced well for infrared heat flow. It’s not as heavy as cast iron, but it sears well and cleans easily. A solid value.
Reasons to buy
- Affordable complete set
- Rust-proof stainless steel
- Easy to clean
Reasons to avoid
- Thinner rods may warp over time
- Not as good heat retention
What to look for
Material Matters
Cast iron gives the best sear but needs maintenance. Stainless steel is rust-proof and easy to clean but doesn't hold heat as well. Porcelain-coated cast iron offers a middle ground—good heat retention with a non-stick surface, but the coating can chip. Aluminum (like GrillGrate) is lightweight and rust-proof but less traditional.
Fit and Compatibility
Not all aftermarket grates fit the Tru-Infrared tray perfectly. Some are too wide or too narrow, which can cause uneven heating or instability. Always check dimensions and user reviews for your specific model. The grates I picked are verified to fit standard 3- and 4-burner units.
Heat Retention vs. Recovery
Thicker, heavier grates (cast iron) retain heat better, so they recover quickly when you flip food. Thinner stainless steel grates cool down faster, which can lead to uneven cooking if you open the lid often. For high-heat searing, prioritize weight.
Our verdict
The GrillGrate is the best all-around performer, but if you prioritize searing, go with the Craycort cast iron. For low-maintenance grilling, the Royal Gourmet porcelain-coated grate is a strong choice.
FAQs
Yes, most aftermarket grates are designed to fit the standard Tru-Infrared models. However, you must ensure the grate sits flat on the ceramic tray without blocking the infrared heat ports. The grates I tested all fit securely and allowed proper heat flow.
Absolutely. Cast iron grates work great with infrared because they absorb and radiate heat efficiently. Just be aware that cast iron requires seasoning and regular oiling to prevent rust. The Tru-Infrared system’s even heat helps maintain seasoning.
For stainless steel, a brass brush after cooking works. For cast iron, scrape off residue and wipe with oil. Porcelain-coated grates can be cleaned with mild soap and water, but avoid abrasive pads. Never use oven cleaner.
Yes, heavier grates (like cast iron) store more heat, so they sear better and recover faster after placing cold food. Lighter grates may drop in temperature more, leading to less crust formation.
Stainless steel is lower maintenance and won't rust, but it doesn't sear as aggressively as cast iron. For infrared, cast iron maximizes the heat output, while stainless steel offers convenience. Choose based on your priority: performance or ease.
