Our Picks at a Glance
How To Choose The Best BBQ Grid Replacement
The most common mistake is ordering by burner count instead of measuring the grate’s physical dimensions. A “4-burner” grate from one brand can be a completely different width than a “4-burner” from another. Always measure your current grate from edge to edge before you click buy.
Material Choice Affects Performance and Longevity
You are choosing between two main materials. Porcelain-coated cast iron holds heat superbly and gives those deep sear marks, but the coating can chip and flake over time. Solid stainless steel is generally rust-proof and easier to clean, but it does not hold heat the way cast iron does. Think about whether you prioritize searing power or low-maintenance longevity.
Exact Fit Prevents Installation Problems
Even when the model number looks right, grates can run slightly narrower or wider than the originals. A half-inch gap might be fine for cooking, but a quarter-inch too wide means it will not sit down into the frame properly. Check the exact dimensions listed, not just the compatible model numbers, and compare them to your original part.

In‑Depth Reviews
1. Hisencn 17 Inches Grill Grates for Nexgrill
Our pick — over 4.5★ from 600+ verified ratings; the strongest balance of quality and price.
This stainless steel upgrade eliminates rust and flaking, outperforming the original cast iron.
Most people replacing Nexgrill grates expect to match the original cast iron, but this pick trades that for 100% stainless steel with 7mm bars — a move that eliminates the flaking-coating problem entirely. Because it is non-magnetic and resists rust, it suits anyone who grills outdoors year-round and is tired of watching original parts degrade. It fits a wide range of Nexgrill 4-burner and 5-burner models, including the 720-0830H and 720-0888N.
What wins people over here is the quality — it is the single most-discussed point, cited by over 50 owners — followed closely by the fit, with over 40 confirming it drops in perfectly. Buyers report using these for a full year with zero issues, and several note they are “better than the original” cast iron they replaced. The smooth surface also means food sticks less, so cleaning is a warm-water-and-soft-brush job rather than a scrape-fest.
The honest trade-off is that stainless steel does not sear quite as aggressively as thick cast iron. If your whole grilling identity is about maximum crust on steaks, this is a small step down. But for even heat distribution up to 830°F and a surface that will not chip, it is the most balanced replacement on this list.
stainless durability
- 100% stainless steel will not rust or flake
- 7mm bars resist warping at high heat
- Non-stick surface cleans up easily
pricey upgrade
- Lighter than cast iron, so sear marks are less pronounced
- Fits Nexgrill models — measure before ordering
top pick: This is the one to grab if you want a permanent fix for flaking grates on a Nexgrill, with the crowd rating it 4.8 across 600+ owners.
budget skip: You insist on cast-iron searing power over rust-proof convenience.
2. Hongso G460-0500-W1 Grill Grates for CharBroil
This porcelain-coated cast iron set delivers pro-level searing at a fraction of the OEM price.
For Char-Broil 2-burner owners, this set is the workhorse pick. Each grate measures 16 15/16″ x 8 5/16″, and the polished porcelain-coated cast iron retains heat superbly, producing the kind of prominent sear marks that stainless just cannot match. It covers a huge compatibility list, from CharBroil Performance and Advantage to Thermos and even Nexgrill 2-burner models.
The thing everyone raves about is the fit — it is the most-mentioned aspect by a wide margin, with over 75 owners confirming it drops in correctly. Value is the second-biggest praise point, with buyers noting they paid about a third of what the manufacturer charges and got a grate that brought their grill back to life. After four months of use, several owners mention zero rust, and the porcelain surface cleans up without a wire brush.
The recurring note is that these run about a half inch narrower than the originals — customers note the gap is noticeable when you first place them, but it does not affect cooking. They are heavy, which is a sign of solid cast iron, but means the box is awkward to lug around.
sear efficiency: At a budget-friendly price point, you get genuine cast-iron heat retention and a fit that owners consistently confirm — the rare budget pick that behaves like a premium part.
fit tolerance: The half-inch narrower fit is the one thing to know before you install, and it is cosmetic, not functional.
value pick: You cook on a 2-burner Char-Broil and want the sear marks back without paying dealer prices.
measure first: You need a perfect edge-to-edge match with the original width.
3. Charbroil Professional TRU-Infrared Replacement Grate & Emitter
This factory-grade set restores TRU-Infrared grills to flare-up-free performance.
This is not just a grate — it is the grate and the emitter plate together, which is exactly what a failing TRU-Infrared system needs. Each section measures 6-inches wide by 17-inches deep, and you buy three sections for a 2-burner grill, four for a 3-burner, and five for a 4-burner. Owners confirm the math works: “3 sets fit perfectly for a 2 burner grill.” The porcelain-coated surface and stainless frame keep flare-ups down and heat even across the cooking surface.
The biggest single feedback point is fit, but it is genuinely mixed — some owners find the sections run narrower than the originals, so measure carefully. That said, the functionality gets consistent praise, with owners noting the grates are lighter than the heavy original pieces and clean up far more easily. One owner with a 3-burner model 463367016 found that 4 pieces matched the exact span of their old 3-piece setup, so the math is flexible.
Durability is the fair caveat here: while some owners say their grill is “like new again,” others report rust within three months. That split means this is a solid official replacement, but you should consider a cover and regular care to get the most from it.
authentic choice: If you want to restore the original no-flare-up performance of a Commercial, Signature, or Professional TRU-Infrared grill, this is the exact matching system.
costly option: Fit and rust reports are split, so check your model year and keep it covered when not in use.
4. Parts DC104 17inch Cast Iron Grids for Nexgrill & Charbroil
A cast iron two-pack that fits an unusually wide range of Nexgrill, Charbroil, and Kenmore models.
Each grate here measures 17″ x 13 1/4″, and the two together span 26 1/2″ — which is why this set covers so many grills, from Nexgrill 4-burner and 5-burner models to Charbroil 4-burner and even Kenmore Sears models. The polished porcelain-coated cast iron handles temperatures up to 500°C, so it is built for serious heat. The compatibility list is long enough that this is a prime candidate if you are unsure of your exact part number but know your grill size.
Quality is what owners praise most here — it is the #1 aspect by count, with over 90 buyers calling it out — and fit is a very close second at over 80 mentions. One owner learned the hard way that “the flat side should be up,” which is the kind of practical tip that saves you a frustrating first cook. Several reviewers point out their grates held up great for 4-6 years, which is a strong longevity signal for a mid-range cast iron set.
The honest caveat is the same one that follows all porcelain-coated cast iron: some shoppers say the coating flaking off over time. The brand even warns in the listing that cast iron grids are fragile and may break in transit, so inspect the box on arrival.
versatile fit: This is your pick if you own Nexgrill, Charbroil, Kenmore, or even Uniflame and want one order to work across a 26 1/2″ span.
maintenance needed: Porcelain coating can chip on heavy impact, and occasional units arrive damaged in shipping.
5. Parts DC115 Porcelain Coated Cast Iron Cooking Grids (Set of 3)
A three-grate kit that saves you from buying a whole new grill when the originals rust out.
This set of three polished porcelain-coated cast iron grids is the fix for grill owners who want to avoid the cost of a new machine. Each grid is 8 5/16″ x 16 15/16″, and the three together span 24 15/16″ x 16 15/16″. It covers a staggering list of brands — Charbroil, Broil King, Costco Kirkland, K Mart, Master Chef, and Kenmore — which makes it a strong “probably fits” candidate for many 3-burner and 4-burner setups.
The #1 praise point is quality, with 80 owners citing it, followed by fit at 69. Owners on Charbroil Gas2Coal 3-burner grills report it fits “perfectly inside the grill,” and several note it was “better than OEM” in at least one respect. The clean-up story is good too — a non-bristle brush and warm water keep them looking fresh after months of use.
The practical warning from owners is to measure before you order. One buyer ordered for a 4-burner without checking width and had to return them — the grates are well made, but the burner count is not the same as the width. Durability gets a mixed read: some owners say rust is not a worry, while others report the coating peeling and flaking.
porcelain coated: At a budget-friendly price, this three-pack is the economical route to reviving a grill where the original parts are beyond saving.
size variance: Burner count and grate width are not the same thing — measure the cooking surface first.
easy clean: You own a Charbroil, Broil King, or Kirkland grill and want a sturdy, well-fitting replacement without the OEM markup.
check dimensions: You cannot confirm the width of your current grate — this one rewards careful measuring.
6. Hisencn 21 inch Grill Grate for Dyna Glo
The dedicated Dyna-Glo fix that restores a five-year-old grill to like-new condition.
If you own a Dyna-Glo 2-burner gas grill, this is the matched replacement. Each piece is 15.5″ x 10.5″, and the two together span 15.5″ x 21″ total. It is made of durable cast iron, which retains and spreads heat more evenly than thinner stamped steel, and it fits the Dyna-Glo DGF350CSP, DGF350SNP, and DGH353CRP lines, among others, with part number 70-01-634.
Fit is what owners praise most — it is the #1 aspect with 69 mentions — and quality follows at 53. One owner said the replacement was “an exact fit” and that it “got my grill back into action” after years of decline. Another noted the quality is “just as good as name brand at 60% of the cost,” which is the kind of value math that makes this an easy sell for Dyna-Glo owners.
The maintenance story is worth reading twice. These are bare cast iron, so the brand advises coating oil before and after use — before to stop sticking, after to stop rusting. If you store the grill for a long stretch, heavy greasing and a covered spot are required. Durability gets mixed reviews: some owners find them heavy-duty, while others report rust after a few weeks, which points straight back to the seasoning routine.
simple swap: This is the pick for Dyna-Glo 2-burner owners who want a precise fit and good cast-iron heat retention at a fair price.
upkeep needed: Bare cast iron needs oiling to stay rust-free, so skip this if you want a set-and-forget surface.
7. Grill Valueparts 463365021 Cast Iron Grates for Charbroil Performance 4 Burner
A chunky enameled cast iron set that restores even heat and bold sear marks to Performance 4-burner grills.
This is the heavy-duty route for Charbroil Performance 4-burner owners. The set includes one large grate at 10 1/2″ x 17″ and two narrow grates at 7″ x 17″, spanning 24 1/2″ x 17″ total. The upgraded enamel cast iron is built to resist rust, chipping, cracking, and deformity, and it holds heat well enough to deliver bold sear marks and even cooking temperatures. It replaces part numbers G426-0005-W1 and G426-0004-W1, covering models like 463365021, 463351021, and 463350722.
Quality is the #1 praise point, with over 50 owners citing it, and fit is close behind at 44. Owners describe the grates as “thick, heavy, the coating is thick and durable,” and several say they are an exact match for the originals. One owner who tried a different model first came back to these, noting “the original ones are the way to go.” The weight — 9.88 pounds — tells you this is genuinely substantial cast iron, not a flimsy stamped substitute.
The recurring note is that these run slightly smaller than the original grates. It is not a functional problem for most, but if you demand a millimeter-perfect edge, this will bug you. Durability also has a mixed read, with some owners reporting rust within a year, so a light oil coating before use is a smart habit.
heat master: Grab this if you want the closest thing to factory-grade searing on a Performance 4-burner without paying OEM prices.
verify size: The slightly smaller fit is the trade-off, and rust resistance improves with a quick oil wipe-down.
8. BBQration 17 x 9 1/2 inch Cast Iron Grates for Charbroil TRU Infrared 4 Burner
A premium three-pack built to revive the 4-burner TRU-Infrared lineup with genuine heft.
This three-pack of matte cast iron grates is the premium fix for Charbroil Commercial, Signature, and Performance TRU-Infrared 4-burner grills. Each grate measures 17″ x 9 1/2″, and the three span 17″ x 28 1/2″ total. It replaces part numbers G541-0016-W2 and G533-0009-W1, covering models like 463242715, 463255020, and 463276016. At 17.96 pounds, this is the heaviest set on the list — you can feel the solid construction the moment you lift the box.
Fit is what owners praise most, with 67 mentions, and quality follows at 49. Owners on 4-burner TRU Infrared grills report the grates “fit PERFECTLY” and are “every bit as heavy as the originals.” One owner even used them to restore a Sabre Grill to “brand new performance.” The construction gets consistent praise — “the quality of the grate is evident in its well-crafted construction.”
The fair caveat is compatibility. If you pair these with a different brand’s emitter plates, the holes can misalign — buyers report one side fitting while the other does not. The brand also notes that if you need a matching emitter, you should search for a specific companion part. Durability has a mixed read, with some owners reporting rust and breakage, so this rewards careful handling.
premium choice: This is the pick for TRU-Infrared 4-burner owners who want heavy, well-crafted grates that drop in perfectly and restore original performance.
check fit: Stick with matching-brand emitters, and handle with care to avoid the rust and breakage some owners mention.
9. SnS Grills EasySpin Charcoal Grill Cooking Grate
The spinning stainless grate that finally makes two-zone charcoal cooking easy on a 22-inch kettle.
This is a completely different animal from the gas grill grates above. Designed for any 22″ kettle grill — Weber Original Kettle, Performer, and MasterTouch included — this 304 stainless steel grate has a large hinged opening that lets you add charcoal mid-cook without disturbing the food on top. The EasySpin feature means you rotate the whole grate by hand to move food closer to or farther from the heat, giving you precision temperature control with zero power needed.
Quality is the thing everyone raves about, with 109 owners citing it — the highest single aspect count on this entire list — and functionality follows at 33. Owners describe it as “heavy duty” and note it “spins easily,” with one calling it “the ultimate Weber Kettle replacement grill grate.” The rust resistance gets its own praise at 19 mentions, which is the whole point of upgrading from the factory steel. One owner summarized it well: it is “not cheap but it will outlast several cheap replacement grates.”
The trade-off is value — it is the priciest pick here by a clear margin, and the value-for-money aspect is rated mixed by owners. It is also slightly less heavy-duty than the original Weber grate, per one owner’s observation, so it is a smart upgrade rather than a bulletproof replacement. The 10-year warranty from the brand helps soften that cost over the long run.
two-zone control: This is the definitive upgrade for Weber 22″ kettle owners who want to sear on one side and smoke on the other with total heat control.
higher cost: You pay more upfront, but the 304 stainless build and spinning mechanism justify it for serious charcoal cooks.
control pick: You grill on a 22″ Weber kettle and want a rust-proof grate that lets you add coals mid-cook and spin food for perfect temperature control.
pricey option: You are on a strict budget or want the absolute heaviest grate possible — this one trades a little heft for the spin feature.
Understanding the Specs
Cast Iron vs. Stainless Steel
Cast iron, often with a porcelain coating, holds heat superbly and produces deep sear marks, which is why most factory grates use it. The catch is that the coating can chip and the metal can rust if neglected. Stainless steel skips the coating problem entirely and resists rust, but it does not hold heat as aggressively — expect slightly less pronounced sear marks in exchange for a surface that lasts longer with less care.
Bar Thickness and Heat Distribution
Thicker bars, like the 7mm on the Hisencn pick, resist warping at high temperatures and distribute heat more evenly across the surface. Thinner stamped bars heat up faster but can warp over time. For gas grills, look for bars that are thick enough to hold heat without bending — the bar thickness is the single spec that tells you whether a grate will stay flat after a few seasons of high-heat cooks.

Final Thoughts: The Verdict
Across the board, the bbq grid replacement winner is the Hisencn 17-Inch Nexgrill set because it trades the flaking-iron problem for a rust-proof stainless surface that owners rate as better than the original. If you want the sear marks back on a 2-burner Char-Broil, grab the Hongso porcelain cast iron set at a value price. And for Weber kettle owners who want total heat control, the SnS EasySpin is the upgrade that changes how you grill — 304 stainless, a large hinged opening, and a spin mechanism no factory grate offers.
