You want real sear marks and juicier results, not flare-ups and cold spots. Swapping your thin wire rack for a cast iron grate delivers that, because cast iron holds heat far better than wire. But not every grate fits every grill, so your first step is to know your exact grill brand and model before measuring anything.
I’m Mohammad Maruf — the founder and writer behind KitchPrep. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Everything here is packed into one clear breakdown of the barbecue cast iron grate options that actually fit, sear, and survive — so you can order with confidence.
Our Picks at a Glance
How To Choose The Best Barbecue Cast Iron Grate
Your grill grate is the only surface between you and dinner, so a wrong pick means a wobbly fit or food that sticks no matter what. The short version: match the brand and model number, then choose between a porcelain-coated finish or bare seasoned cast iron.
Match your grill model first
Every grate below is designed for a specific family of grills — Weber Spirit and Genesis, or Char-Broil and Char-Griller models. Measure your current grate before ordering, because a quarter-inch difference in length or width means it won’t sit flat over the burners, which ruins heat distribution and leaves you with uneven cooks.
Porcelain-coated vs. bare cast iron
Porcelain coating gives you the heat-retention of cast iron with an easy-to-clean surface that resists sticking, and without the rust risk that bare iron carries. Bare cast iron delivers the most aggressive searing but demands seasoning and indoor storage to stay rust-free — a simple habit, but one beginners often forget.

In-Depth Reviews
1. Hongso Grill Grates for Chargriller
Our pick — over 4.5★ from 750+ verified ratings; the strongest balance of quality and price.
The crowd-favorite Char-Griller fix that makes a worn-out grill look brand new.
If your Char-Griller gas grill (models 2121, 2222, 2828, and more) has grates past saving, this four-piece set is your fix. Each grate measures 19 3/4 x 6 3/4 inches, giving you a full 19 3/4 x 27 inch cooking surface. The porcelain coating over cast iron makes cleanup easy — food releases instead of fusing to the metal.
The weight here tells the story: at 17.46 pounds, this is a heavy, dense set that soaks up heat and holds it, which is what produces those prominent sear marks. Buyers report a perfect drop-in fit for their Char-Griller models, with one typical note being that the grates fit the grill perfectly and, combined with new heat shields, made the whole grill look brand new.
These are roughly 55% heavier than the Leship Weber set below — 17.46 pounds versus 11.25 pounds. That extra mass means noticeably better heat retention on a gas grill that loses temperature when you open the lid.
What wins people over
- Porcelain coating means easy clean-up after every cook
- Fits a huge range of Char-Griller and King Griller models
- Holds heat superbly for strong sear marks
The honest trade-off
- Lacks the little tab that secures into some grills
- You must measure your original grates before ordering
The pick for: Char-Griller owners who want a heavy, easy-clean upgrade that restores a tired grill.
Keep in mind: a few reports note the missing retaining tab, so check how your current grates lock in.
2. Leship 17.5 inch Grill Grates for Weber
The affordable savior for Weber Genesis owners whose grill is too old for OEM parts.
For an older Weber Genesis gas grill that Weber no longer supports, this two-piece set is a lifeline. Each grate is 17.5 x 11.9 inches (a full 17.5 x 23.8 inches across both), and it fits Spirit 300 series, Genesis 1000-3500, Gold, Silver, and Platinum models by replacing original part numbers 7638, 7639, 7525, and more.
The 13.5-pound heft tells you this is solid cast iron that retains heat superbly and delivers prominent sear marks on steaks and burgers. The owner feedback leans heavily on one theme: these look and perform just like the originals from a decade ago, at a fraction of the Weber-branded cost. As owners mention, the fit on a Genesis 300 series grill is perfect, and the result is an old grill brought back to life.
Where it edges out the GasSaf option below is the depth of coverage for vintage Genesis models — if your grill dates back to the 1990s or early 2000s, this is the safer bet.
The strong points
- Perfect for discontinued Weber Genesis models
- Heavy cast iron with zero rust reports over years of use
- Much cheaper than OEM Weber replacements
The catch
- Verify your model is on the compatibility list
- No porcelain coating, so seasoning matters
Reach for it if: you own a legacy Weber gas grill and want original-quality cooking without the original price.
Look elsewhere if: your grill is a GS4 Spirit II, which needs a different kit.
3. 463448021 Grill Grates for Charbroil Performance
The enameled Char-Broil rescue that turns an impossible-to-clean grill back into a daily cooker.
Char-Broil Performance 5-burner owners know the struggle: original grates are a nightmare to clean. This three-piece set — two large grates at 10 1/2 x 17 inches each plus one narrow at 7 x 17 inches, totaling 28 x 17 inches — replaces Char-Broil part numbers 463448021, 463449021, 463450022, and more with upgraded enameled cast iron.
At 11.25 pounds for the set, it’s noticeably lighter than the Hongso pick above, which makes it easier to lift in and out for cleaning, while the enamel coating resists rust, chipping, and cracking. The buyer story here is striking: one owner gave up on their two-burner Char-Broil entirely because cleanup was impossible, and these grates brought it back into service. The fit earns the most praise by far — 30 owners single it out — with better searing a close second.
The honest note is size: a handful of buyers find the grates run slightly small and sit a little loose, so if your grill is on the outer edge of the model list, expect to verify carefully.
The bottom line: the best low-cost fix for Char-Broil owners who want enameled durability and far easier cleaning than the factory parts.
Choose this if: your Char-Broil Performance’s cleaning hassle has you ready to quit grilling.
Think twice if: you want a perfectly snug fit — a few units sit slightly loose.
4. GasSaf 7638 Grill Grates for Weber Spirit
The heavy-duty Weber Spirit upgrade praised most for sheer build quality.
For Weber Spirit 300 series and vintage Genesis grills, this two-piece set delivers exactly what cast iron promises: dense construction at 13.99 pounds, superb heat retention, and sear marks you can actually see. Each grate is 17.5 x 11.9 inches, with the pair covering 17.5 x 23.8 inches, and the compatibility list is vast, from the Spirit E310 and E330 to the Genesis 1000-3500 series and beyond.
Quality is the single most-mentioned point — 62 owners praise it — with fit right behind at 52. The feedback pattern is clear: these are heavy-duty, clean easily, and last without rusting, with owners noting the grates give a decades-old grill a new lease on life when the originals had finally deteriorated. The description pairs them with almost any heat source — gas grills, electric burners, even charcoal ovens.
The one rare complaint involves a chipped edge arriving in transit, a shipping hazard rather than a design flaw. If your Weber matches the 7638 footprint, this is a beefier alternative to the Leship set, though Leship covers more vintage Genesis models.
Why it stands out
- Build quality is the most-praised feature by a wide margin
- Works on gas grills, electric burners, and more
- Pre-seasoned to reduce sticking
Good to know
- An occasional unit arrives with a chipped edge from shipping
- Always compare dimensions to your originals first
Best for: Weber Spirit owners who want a dense, non-rusting grate that cooks like the original did on day one.
Not ideal if: you own a discontinued Genesis model outside the 2000-2010 window.
5. Cast Iron Grill Grates for Charbroil TRU-Infrared
The drop-in Char-Broil TRU-Infrared replacement that sears better than the factory plates.
This three-piece set targets Char-Broil TRU-Infrared 3-burner grills specifically, covering a long list of model numbers like 463242516 and 463242515, plus Signature and SmartChef variants. Each grate is 17 x 7 1/2 inches (17 x 22 1/2 inches total), and the package includes three premium stainless steel emitter plates, which is what makes the infrared system work.
The 1-pound listed weight is the lightest here — genuinely easy to handle — yet the cast iron still delivers excellent searing with even heat distribution. Customers note an exact fit for their Commercial 3-burner, noting the grates look just like the originals while costing less and arriving faster than a trip to the hardware store. The fit is the top praise at 36 mentions, with quality close behind at 22.
The mixed note is rust resistance: some owners see none, while others report rust forming. That split is typical of cast iron, so a light oiling after each cleaning keeps the surface protected.
The verdict: an easy, affordable resurrection for TRU-Infrared owners, provided you keep up a simple oiling habit.
Grab it if: you’re on a Char-Broil TRU-Infrared 3-burner and want original fit with better searing.
Pass if: you skip grate care entirely — bare cast iron needs a light maintenance routine.
6. onlyfire 2-in-1 Cast Iron Grill Grate for Weber Kettle
The two-piece Weber Kettle grate with a removable center for adding charcoal mid-cook.
This isn’t a straight swap — it’s a cooking-system upgrade for Weber 22.5-inch Kettle charcoal grills. You get a 21.5-inch outer grate with a hole, plus an 11.8-inch inner sear grate that lifts out using raised side handles, so you can add charcoal without lifting the whole surface and ruining your sear. It fits the Original Kettle, Performer Premium, and Kettle Premium models.
At 8 pounds, it’s not the heaviest option here, but the cast iron delivers even heat and professional searing. The design has real fans: reviewers point out their steaks and chicken wings cook like a champ, and coastal dwellers note it’s held up wonderfully after eight months where wire racks used to rust out yearly. One owner survived an 800°F vortex without a crack — a serious stress test.
The honesty check: real cast iron demands care. The owner feedback is clear that you should season it thoroughly before first use (an oil soak and hours of heat is the described method) and clean with oil and a plastic scraper rather than metal tools.
What makes it special
- Removable center lets you add charcoal mid-cook without lifting the grate
- Replaces flimsy wire racks that rust out quickly
- Survived extreme heat tests without cracking
What to know
- Needs serious seasoning before first use
- Bare iron must be stored indoors to avoid rust
Pick this for: Weber Kettle owners who want the flexibility of a removable sear grate for charcoal management.
skip it if: you’re not ready to season and baby your cast iron — this one demands it.
7. Aura Outdoor 22-Inch Cast Iron Grill Grate
The porcelain-enameled 22-inch Kettle grate built for perfect grill marks with minimal fuss.
If your priority is sear marks and you’d rather not manage bare cast iron, this is your grate. It measures 21.5 x 0.5 inches and drops into Weber Kettle grills, the Recteq Bullseye, and other 22-inch kettle-style cookers, with the porcelain enamel coating making food release easy and clean-up faster than you’d expect from cast iron.
The 8-pound weight feels substantial without being awkward, and the pre-seasoned surface means flipping burgers and chicken is simple. The most-praised feature is grill marks — 35 owners call it out — with fit and cooking performance close behind. On a Recteq Bullseye, shoppers say it works for both smoking and high-heat grilling with no sticking after a simple seasoning at 450°F.
The durability conversation is genuinely mixed: some buyers report small cracks forming on first high-heat use (which they call harmless), while others had one crack and none since. A rare professional chef reported two defective units with pieces falling out. The majority are thrilled, but this is the one pick where heavier use seems to reveal more variation.
The appeal
- Porcelain enamel makes cleanup genuinely easy
- Prominent grill marks are the top praised feature
- Works for smoking and high-heat grilling
The risk
- Some units develop small cracks on first high-heat use
- A rare unit arrives with defective fabrication
Reach for this if: you want easy-clean searing on a 22-inch kettle without the bare-iron rust routine.
Be cautious if: you regularly run screaming-hot fires — that’s where cracks most often appear.
8. Uniflasy 8835 Cast Iron Grill Grate for Weber Kettle
The 20-pound Weber Kettle behemoth that cooks like the grills of the olden days.
At 20.3 pounds, this is the heaviest grate in the lineup, and that mass is the point. It fits 22.5-inch Weber charcoal grills — One-Touch, Master-Touch, Performer Deluxe, and more — with a 21.5-inch total grate and a 12-inch inner insert that lifts out via raised side handles, so you can add briquettes or wood chunks mid-cook. It also fits the Recteq Bullseye and Pit Barrel Smoker.
Buyers praise quality 61 times and fit 38 times. One owner calls it super heavy-duty, perfectly fitting, and easy to clean, swearing it’s the best upgrade yet for burgers and hotdogs. Another says it reminds them of olden days grills, praising the professional searing and flavor sealing.
The recurring wish is that the removable insert were a bit larger to fit a charcoal chimney starter through it. Durability is mixed — some report heavy-duty performance while others see cracking on first use, so a gentle first burn-in is worth your time.
Why it impresses
- Massive 20.3-pound cast iron holds heat like nothing else here
- Center insert simplifies adding charcoal mid-cook
- Quality is the most-praised feature by a wide margin
The trade-off
- Center hole could be bigger for a chimney starter
- A few owners mention cracking on first use
Get this if: you want the densest, most traditional cast iron searing available for a 22-inch Weber Kettle.
Reconsider if: you lift your grate in and out often — 20.3 pounds gets old fast.
Understanding the Specs
Porcelain Coating vs. Bare Cast Iron
Porcelain-coated grates give you cast iron’s heat retention with a smooth, non-stick surface that resists rust and wipes clean easily — perfect for gas grills where flare-ups are common. Bare cast iron sears harder but needs seasoning and dry storage to stay rust-free. Choose based on how much maintenance you’ll actually do.
Weight and Heat Retention
A heavier grate (think 17 to 20 pounds) absorbs more heat and holds it, so your sear doesn’t disappear the moment cold meat hits the surface. Lighter grates heat faster but lose temperature quickly when the lid opens. Heavier always cooks better, but it’s harder to lift in and out for cleaning.

If you own an older Weber Genesis, the Leship 17.5-inch set is the affordable restoration you’ve been hunting for. And for a 22-inch Weber Kettle where sear marks matter most, the Uniflasy 8835 delivers the heaviest, most traditional cast iron cooking of the list.
