Finding the best cast iron grill grates for charcoal grills comes down to one number most listings bury: the actual diameter of the cooking surface. Cast iron stores heat the way a brick stores heat, so a heavy grate sears hard, keeps cooking after the coals fade, and lays down grill marks you can actually read. The catch is fitment, because a cast iron cooking grid is a model-specific part, not a universal one.
We should concede the strongest objection first. The number one result for this query tells readers not to bother with cast iron, and the valid part of that argument is rod spacing. Thick cast iron rods sit closer together than thin steel bars, so less smoke passes through and contacts the food. That is a real effect. It is also a design variable, not a material law, which is why the grates below are judged partly on rod spacing and the open area above it.
One more fact worth stating plainly before any shopping: Weber does not sell a complete cast iron grate as a cooking surface replacement for most of its charcoal kettles. Owners searching for a Weber cast iron grate are usually looking at a third-party part for a 22-inch or 22.5-inch bowl, plus the factory plated steel lower fuel grate. If you are still choosing a cooker, our beginner charcoal grill picks cover the fitment question from the other end.
How we picked: we compared all 12 grates on eight criteria drawn from what owners argue about most often in grill forums and what the top competing guides actually measure. Heat-up penalty, thermal reserve after coals are spent, grill-mark definition, rod spacing and open smoke area, weight and handling, rust and maintenance burden, coating failure risk, and non-stick performance once properly seasoned. Every rating and review count quoted here is taken directly from the listing. We are not affiliated with any of these brands, and a couple of them ship with far thinner social proof than the category deserves, so we flag that too.

1. Weber Factory Charcoal Grate for 22-Inch Kettle Grills: The Exact-Fit Baseline
Weber® Replacement Charcoal Cooking Grate for 22″ Kettle Grills
17 in heavy gauge plated steel
1.4 kg
Fits 22 in Weber kettles
Pros
- Drops straight into 22 in and 22.5 in Weber bowls
- Opens airflow between the vents and the coals
- Moisture and weather resistant plating
- Backed by a 1 year limited warranty
Cons
- This is the lower fuel grate not a cooking surface
- Does not fit 18 in Weber models or the Smokey Mountain Cooker
We put this one first for a reason: it is the part you need regardless of which cast iron cooking grate you choose. It sits under the charcoal, holds it above the vents, and keeps airflow moving so the coals burn the way Weber designed them to.
The owner record here is enormous. A 4.8-star average across 4867 reviews, with 87 percent five-star, is the deepest sample in the guide, and the recurring theme is simply that it fits. If you have a 22-inch One-Touch, Master-Touch, Bar-B-Kettle, or Performer, this is a bolt-in part with no measuring involved.
Be clear-eyed about one thing: this is not a cast iron cooking grate and it will not give you cast iron searing. It is the fuel grate, and its job is airflow. The cooking grid sits a full layer above it, and that upper layer is where a cast iron upgrade pays off.
The steel is heavy gauge and holds up to weather, which matters if your kettle lives outside year-round. Rated to a 500 degree F maximum setting, it is not intended for the searing zone of a kamado, but on a kettle charcoal grill that is nowhere near the temperature range it sees.
Best Cast Iron Grill Grate Pairing for Weber 22-Inch Kettle Owners
Pair this fuel grate with the Uniflasy 8835 cast iron cooking grid listed below and you have a matched system. The lower grate sets the airflow, the cast iron upper grid does the searing, and both parts are model-documented rather than guessed.
What You Give Up by Skipping a Cast Iron Cooking Grid
You keep excellent, even cooking on a thin plated steel grid. What you lose is thermal reserve and grill-mark definition, which is exactly the complaint that drives most owners to search for a cast iron replacement in the first place.
2. Uniflasy 8835 Cast Iron Grill Grate for Weber 22 and 22.5-Inch Kettles
Uniflasy 8835 Cast Iron Grill Grate for Weber 22 and 22.5 in Kettle Grills Gourmet BBQ System
21.5 in outer diameter
12 in center insert
20.3 lb cast iron
Pros
- Exact drop-in fit across 22 in and 22.5 in Weber bowls
- Removable 12 in center insert for adding charcoal
- Prominent sear marks and a better crust
- 90 day warranty with free replacement parts
Cons
- Very heavy to lift in and out
- Center hole will not accept a chimney starter
- Grate claw tool in the photos is not included
This is the cast iron upgrade most 22.5-inch Weber owners end up buying, and the fit data behind it is unusually specific. It covers the One-Touch Silver, Bar-B-Kettle, Master-Touch, Performer, Performer Deluxe, Original Kettle Premium, Smokey Mountain Cooker, plus the Recteq Bullseye and Bullseye Deluxe.
At 20.3 pounds it is the heaviest grate among the round cookers covered here, and that is not a complaint so much as a fact you plan around. Owners overwhelmingly describe the searing as a step up from factory steel, with a crust and grill marks that are visibly deeper.
The 12-inch removable center insert is the feature that changes daily cooking. You lift the insert, add charcoal, and drop it back in rather than clearing the whole cooking surface. On a long cook that is the difference between a two-minute fix and a ten-minute rebuild.
Two caveats come up repeatedly. The insert opening is too small for a chimney starter, so you need a funnel or a different charcoal method, and the grate claw shown in the product photos is not in the box.
Best Cast Iron Grill Grate for Weber 22.5-Inch Performer Owners
The Performer and Performer Deluxe are explicitly on the fit list, which is rare in this category. It also fits the 22-inch Original Kettle, so if you are unsure which Weber generation you own, this one covers the widest span of the bowl grills here.
Why the Extra Weight Matters More Than the Price
That mass is the entire point. A heavy grate absorbs heat during preheating and then radiates it back, so your steaks still sear after the charcoal has burned down to ash and the internal grill temperature has dropped.
3. Aura Outdoor Products 21.5-Inch Cast Iron Grill Grate for Recteq Bullseye and Barrel Grills
Cast Iron Grill Grate for 22 Inch Weber Kettle Grill, Better Sear Marks
21.5 x 0.5 in round grid
8 lb cast iron
Pre-seasoned surface
Pros
- Excellent grill marks and crust on steaks and poultry
- Handles very high heat without warping
- Non-stick pre-seasoned surface
- Cleanup is mostly a burn-off
Cons
- A portion of owners report cracking on a first high heat fire
- One pro chef reviewer returned four grates for cracking
- 9 percent one-star share is the highest in the 22 in group
At 8 pounds, this is a lighter cast iron grate than the heavy two-level models, and the cooking results owners report are close to identical. The 21.5-inch diameter is the same footprint as the Weber 22.5-inch options, so it covers Recteq Bullseyes, barrel grills, and Weber kettles in one part.
The finish is pre-seasoned with a porcelain enamel coating, which is why food releases cleanly on a first cook and why cleanup is usually a burn-off rather than a scrub. That coating is also the source of the product’s most serious complaint.
Cracking on an early high-heat fire is the defining issue here. It is not universal, but it is real enough that 9 percent of reviews are one-star, and one professional chef reviewer returned four separate grates for the same defect.
The pattern among owners who have no problems is consistent: they season the grate carefully, they avoid piling all the charcoal under a single dual-zone grid, and they ramp heat more slowly. The single-zone cast iron layout is more demanding than a three-piece stainless setup.
Best Cast Iron Grill Grate for Recteq Bullseye and Barrel Smokers
Owners running a Bullseye or a barrel smoker call out high-heat durability specifically, and several report cooking on it without warping. For a barrel where the fire box runs hotter than a kettle, that is the relevant data point.
Why the Enamel Coating Is a Double-Edged Choice
Enamel gives you a non-stick surface out of the box and kills the seasoning chore, but cast iron under enamel still rusts if a chip exposes the bare metal. A bare cast iron grate, once seasoned, has no coating to lose and no chip failure mode at all.
4. onlyfire 2-in-1 Cast Iron Grill Grate for Weber Original Kettle Premium
onlyfire 2-in-1 Cast Iron Grill Grate Replacement Weber Gourmet BBQ System
21.5 in outer plus 11.8 in insert
8 lb uncoated cast iron
1452 sq in surface
Pros
- Drops into 22 in kettles with no fitting
- Real uncoated cast iron that owners prefer for durability
- Removable center doubles as charcoal access
- Clean cast finish with no flashing
- Survives a high heat charcoal ring
Cons
- One reviewer reports the center ring snapped after a few uses
- That review never received the promised replacement insert
- Needs a deliberate seasoning routine first
- Insert is thinner than the Weber Genuine Sear Grate
Owner writing makes this one of the better-documented cast iron upgrades in the guide, on review detail rather than review count. The single most-detailed review on the listing is a full seasoning walkthrough that confirms this is genuine uncoated cast iron, not a coated imitation, and that it holds together under a high-output charcoal ring without cracking.
It is a two-piece system: a 21.5-inch whole cooking grate and an 11.8-inch inner sear grate with raised side handles. That gives you 1452 square inches of listed cooking surface, which is far more usable area than the single-level grates listed here.
Uncoated cast iron is a deliberate choice here and it cuts both ways. There is no enamel to chip and no coating to flake, so the failure mode that ends a coated grate simply does not exist. In exchange, you own the seasoning and rust maintenance from day one.
Manufacturing oils are still on the grate when it arrives, so burn them off before the first real cook. The top review on the listing walks through exactly this, and following it is the difference between a grate that seasons well and one that stays blotchy.
Best Cast Iron Grill Grate for Weber Original Kettle Premium and Performer Premium
Those two models are named directly in the fit list, alongside the Original Kettle. The three-piece stainless arrangement most Weber owners run is exactly what this two-level cast iron layout replaces, and owners report the sear difference immediately.
When the Center Ring Is Not the Right Answer
It costs a little more and it is heavier, but it gives you a small dedicated searing zone. If you mostly grill burgers and vegetables on a wide surface, the single-level grates listed below do the same job with one less part to maintain.
5. Votenli C883E Cast Iron Grill Grate for Weber 22.5-Inch Kettle Grills
Votenli C883E Cast Iron Cooking Grid Grates Replacement for Weber 22.5 inches One-Touch Silver, Bar-B-Kettle, Master-Touch and One-Touch
21.5 in diameter
12 in inner grid
Single level configuration
Pros
- Exact fit for the listed Weber 22.5 in models
- Even heat retention and distribution
- Professional level sear marks
- Faster searing than the onlyfire setup but less versatile than the Uniflasy
Cons
- Smallest review base in the 22 in group at 296
- Manufacturer advises inspecting cast iron on delivery
- Listed cooking surface area is far lower than the 2-in-1 grates
- Center insert is smaller than Uniflasy and onlyfire
This is the straightforward single-level cast iron answer for a 22.5-inch Weber bowl. One 21.5-inch round grate with a 12-inch inner cooking grid, and that is the whole part. No insert to drop, no second level to store.
The fit list covers the Original Kettle Premium, Original Kettle, Performer Premium, Performer Deluxe, Master-Touch, Smokey Mountain Cooker, and the 22.5-inch charcoal smoker. Owners confirm the fit is accurate rather than approximate.
What you give up versus the 2-in-1 systems is usable cooking surface. The listed area of 361.66 square inches is a fraction of what the onlyfire 8835 offers, so on a busy cook you will be working in more passes.
The manufacturer itself advises inspecting the grate carefully on delivery because cast iron can arrive chipped. That is unusual candor for a parts listing, and it is worth taking them at their word the first time the box opens.
Best Cast Iron Grill Grate for Weber Owners Who Want One Simple Part
If your only goal is a heavier, more even cooking surface with deeper grill marks than factory steel, this does that and nothing more. Simplicity has real value in a part you will lift over a hot fire every weekend.
Why We Would Not Choose This Over the Uniflasy 8835
Both are 21.5-inch grates for the same bowls, and the Uniflasy has roughly twice the review history, a longer warranty, and a larger documented center opening. If the two land close together, the better-tested part is the easier choice.
6. Kamado Joe Half-Moon Cast Iron Grill Grate for Big Green Egg and Kamado Cookers
Kamado Joe Durable Half-Moon Cast Iron Cooking Grate with Grill Grate Lifter for Classic Joe 18-inch Charcoal Grill and Smokers in Black, Model KJ-HCICG
Half moon cast iron grid
7 lb
18 x 9 in per piece
Pros
- OEM grade part for the Classic Joe and 18 in round kamados
- Excellent heat retention for searing
- Works with divide and conquer racks
- Includes a cast iron grate lifter
- Three year warranty
Cons
- Half moon piece so two are needed for a full surface
- Only fits 18 in round kamados
- Rectangular shape is tied to the divide and conquer system
This is the factory grid from Kamado Joe, and the review record is the strongest we could find in the kamado half of the guide: 4.8 stars with only 1 percent one-star reviews. Owners talk about heat retention for searing and about the included lifter in roughly equal measure.
Each piece is a half moon, 18 by 9 inches, so two of them make a full 18-inch round cooking surface. That layout is what makes the divide and conquer system possible, letting you cook directly over the fire on one side and indirect on the other.
Fit is the entire constraint here. It covers the Classic Joe series, the Large Big Green Egg, and other 18-inch round charcoal grills. It will not cover 19.5-inch or 22-inch cookers, so an Akorn or an Oval needs a different part entirely.
The included cast iron lifting tool matters more than it sounds. A kamado runs hot enough that a bare-hand lift is a burn risk, and having the OEM tool in the box removes one more accessory purchase from the list.
Best Cast Iron Grill Grate for Kamado Joe Classic and Big Green Egg Owners
If your kamado is 18 inches round, this is the OEM part, backed by a three-year warranty. The 655-review history is the deeper sample, and it means a predictable replacement rather than a gamble.
When a Half-Moon Layout Is the Wrong Shape
If you want a full flat surface with no split, or your kamado is not 18 inches round, a full round grate is the correct part instead. The Dracarys and BBQration options below fill those gaps for smaller and larger cookers.
7. Dracarys 15.5-Inch Cast Iron Grill Grate for Medium Big Green Egg and Fire Pits
15.5″ Cast Iron Grate Grids Sear Grate Fire Pit,Dracarys Round Cooking Grate big green egg accessories Fit for Medium Big Green Egg Grill Dome Char-Griller or Same Size Charcoal Grill(Medium – 15.5″)
15.5 in round high density cast iron
6.7 lb
Cast iron outer, steel inner
Pros
- A dependable low cost route to put cast iron under a medium Big Green Egg
- One owner has run it as his standard grate for six years
- Noticeably better grill marks than the original wire grate
- Doubles as a fire pit grate
- Care instructions included for rust prevention
Cons
- Sold in 15.5 in and 18 in variants so check your size carefully
- Sits a little higher than the factory grate
- Heavier than the grate it replaces
- Round only with no half moon option
This grate covers more cooker types than the others here. It fits a medium Big Green Egg, Char-Griller ceramic grills and smokers, 15.5-inch fire pits, and at least one owner fits it in a Weber Jumbo Joe 18 without losing cooking space between the handles.
At 6.7 pounds it is among the lighter cast iron grates here, which makes sense for a smaller cooker where the surface area is also smaller. The high density casting is rated well above normal grate temperatures and does not deform under a direct flame.
The one thing to get right is size. This is sold in a 15.5-inch and an 18-inch variant, and reviewers repeatedly warn that they are entirely different parts. Order the wrong one and you will find out immediately when it will not sit down inside the rim.
Long-term ownership is where this part earns its place. Six years of continuous use as a standard grate is the kind of report that a newer listing cannot match, and the grill mark improvement over the factory wire grid is the most common owner comment.
Best Cast Iron Grill Grate for Medium Big Green Egg and Fire Pit Cooking
It is a well-priced route to putting cast iron under a smaller kamado, and the fact that it doubles as a fire pit grate means one part covers two jobs. For anyone with a medium Egg and a fire pit, that is hard to argue with.
Why This Is Not the Grate for a Large Kamado
At 15.5 inches it is sized for the medium Egg, not the Large. Owners running a Large Big Green Egg need the 18 3/16-inch grid below, and buying the smaller part is the most common sizing mistake we see in kamado listings.
8. BBQration 18 3/16-Inch Cast Iron Grill Grate for Big Green Egg Large
BBQration 18 3/16″ Cooking Grate for Big Green Egg Large CIF999A Matte Cast Iron Grid Grates Replacement Parts for Big Green Egg Grate, Kamado Joe Classic, Vision Grill VGKSS-CC2, B-11N1A1-Y2A
18 3/16 in matte cast iron grid
Replaces BGE 18CI and 18SS
1-pack
Pros
- Heavier and more durable than the grate that ships with the Big Green Egg
- Perfect fit reported by multiple owners for the Large
- Matte cast iron finish looks and feels durable
Cons
- One reviewer found it undersized for a Kamado Joe Classic
- Cross bars extend past the circle leaving sharp edges
- Listed weight of 16 oz does not match reality
- Included half moons are smaller than factory and slip off
The factory Big Green Egg grate is a wire grid that sags and warps with use, so upgrading to cast iron is one of the most felt improvements on that cooker. Owners consistently describe this as noticeably heavier duty and better at holding heat than what came with the grill.
The part number coverage is the real strength here. It replaces Big Green Egg 18CI, 18SS, and 18P, plus Vision Grill parts including VGKSS-CC2, and Kamado Joe Classic II and III references, which gives it the broadest cross-brand fit list in this guide.
Measure before you order. At least one reviewer found it roughly three-quarters of an inch short at the bottom edge on a Kamado Joe Classic, where it would not sit securely on the rack. A tape measure against your original grate removes all doubt.
The listed item weight of 16 ounces is wrong, and we are flagging that so you are not surprised when the box is much heavier than the spec page suggests. It is a solid cast iron part in practice. Some buyers also note that the cross bars run past the circular edge, which leaves sharp corners to be careful of.
Best Cast Iron Grill Grate for Big Green Egg Large and Vision Grill Owners
For a Large Big Green Egg specifically, the fit is reported as accurate by multiple independent owners. That is the confidence level you want when a replacement part has to sit on a rack inside a hot ceramic shell.
Why the Half-Moon Add-On Matters Less Than It Sounds
The kit includes half-moon grates for the divide and conquer system, and reviewers find them smaller than factory and prone to slipping. If you use that system, buy the OEM half moons from Kamado Joe instead and keep this grate as your full surface.
9. Gcostar 19.5-Inch Cast Iron Grill Grate for Char-Griller Akorn Kamado
19.5″ Grill Grate for Char-Griller Akorn Kamado, Round Cast Iron Grid
19 3/4 in outer diameter
7 1/4 in center insert
11.08 lb cast iron
Pros
- Confirmed fit in Char-Griller Akorn and Charbroil grills
- Has revived aging grills instead of replacing them
- Solidly supports heavy loads
- Removable center insert for easy charcoal adds
- Matte enamel finish resists rust
Cons
- Not universal across all 20 in grills
- Will not fit the Akorn Jr
- One reviewer found it slightly undersized
- Listed product dimensions do not match the stated diameter
The Akorn and its family of 20-inch kamados have a factory grate that ages quickly, and this is a common repair path owners report finding. Multiple reviews describe the grate as reviving a grill they were otherwise ready to replace, which is the cheapest outcome available when a whole new cooker is the alternative.
The model list is long and specific: Char-Griller Akorn models 16620, E16620, 06620, 6020, 6520, E6520, 6620, 6719, 16619, 16820, and E56720, plus PitBoss K24, Louisiana Grills K24, and the Expert Kamado 20-inch ceramic grill.
At 11.08 pounds this is a genuinely heavy grate, and owners describe it as solidly supporting whatever you put on it. The 7 1/4-inch center insert lifts out for charcoal additions, which is a convenience you will use every long cook.
Two fit warnings are worth repeating. It does not fit the Akorn Jr, and a few buyers report it running slightly smaller than the original grates it replaces. The listing’s own product dimensions also do not agree with the stated diameter, so trust the 19 3/4-inch outer measurement, not the box.
Best Cast Iron Grill Grate for Char-Griller Akorn and PitBoss K24 Owners
The matte enamel coating is the differentiator on this one. It resists rust without a full seasoning routine, which on a kamado that sits outside year-round means far less maintenance between cooks.
Why You Should Confirm Your Model Number Before Ordering
This is a model-specific part with a long fit list and an explicit exclusion. Check the stamped model number on your grill’s cart or the label under the lid, and match it against the list above before you order anything.
10. GGC 4-Piece Cast Iron Grill Grate Set for Char-Griller and King Griller
GGC 19 3/4″ Grill Grates for Chargriller, 4PCS Cast Iron Replacement Grates for Chargriller 3001, 5050, 3008, 3030, 3725, 4000, 5252 and King Griller 3008, 5252
4 bars at 19 3/4 x 6 3/4 in
7.39 kg set
Matte porcelain cast iron
Pros
- Exact fit reported consistently across Chargriller models
- Largest review base of any cast iron grate in the guide
- Broad fit list covering dozens of models
- Also usable for charcoal and oven cooking
Cons
- Porcelain coating can chip in transit
- One buyer received two grates with cracked ends
- Cast iron is porous and needs covered storage
- Grates run very hot during cooking
This is the most proven cast iron grate in the guide by owner volume, with 1044 reviews at a 4.7 average and an 84 percent five-star share. No other cast iron grate here matches that sample size, which matters when you are replacing a safety-adjacent component on a large grill.
It is a four-bar set. Each bar measures 19 3/4 by 6 3/4 inches and together they span 19 3/4 by 27 inches, which is the standard layout on Char-Griller offset smokers and the King Griller models they are built alongside.
The fit list is where this part earns its value. It covers Chargriller 2121, 2123, 2222, 2828, 3001, 3008, 3030, 3072, 3232, 3725, 4000, 4001, 4008, 4208, 5050, 5072, 5252, 5650, and 9020, plus King Griller 3008 and 5252, replacing original part CG2121.
Inspect the set on arrival. One reviewer received two bars with cracked ends and used them anyway, and another found the porcelain coating already missing on delivery. Porcelain-coated cast iron has no repair path once the coating breaks, which is the failure mode described in more detail below.
Best Cast Iron Grill Grate Set for Char-Griller Offset Smoker Owners
If you own a barrel or offset from this family, this is the pick we would make with the least hesitation. A thousand reviews across a shared fit list means the failure cases are already documented, and most of them are transit damage rather than a defective part.
Why Covered Storage Is Non-Negotiable With This Set
Cast iron is porous and this coating only slows corrosion, it does not stop it. Owners who store these grates outside uncovered report rust within a season, and the set is heavy enough that leaving it on the grill overnight is the wrong habit.
11. Utheer 2-Pack Cast Iron Grill Grate for Oklahoma Joe’s Longhorn Offset Smoker
Utheer Cast Iron Grill Grates for Oklahoma Joe’s Longhorn, Better Searing
18.85 x 19.2 in bars
2 pack
3.31 kg set
Pros
- Confirmed perfect fit in Longhorn and Canyon offset grills
- Lowest cost cast iron grate in the guide
- Direct replacement for the OEM part number
- Smoother finish and easier cleaning than the originals
- Several owners replaced worn factory grates with these
Cons
- Thinner than factory grates with a 3 to 4 year expected life
- Smallest review base here at 64 reviews
- Air drying before storage is essential
This is the value pick for offset smoker owners, and the fit confidence comes from part numbers rather than marketing. It replaces Charbroil references CHR1767150, 1767150, and B01E5ER4XM, and covers the Longhorn Combo 12201767, 15202029, 16202046, 14201767, and 18202083.
Multiple reviewers call the fit perfect and the performance equal to the factory grates they replaced, with several noting that their original grates wore out considerably faster. The surface finish is smoother than the factory finish, so it seasons more readily.
Be realistic about gauge. These bars are thinner than the factory grates and one owner estimates a service life of roughly three to four years, which is still a good outcome for a budget replacement but is not the outlive-the-grill promise that heavier cast iron carries.
The cleaning routine is simple and it has to be followed. Soap, water, a brush, and air drying in the sun before storage, and the rust never gets a chance to start. The listing states this directly and owners confirm it works.
Best Cast Iron Grill Grate for Oklahoma Joe’s Longhorn and Canyon Owners
For these two specific grills, the OEM part number cross-reference removes almost all of the guesswork that makes replacement parts risky. You are matching a stamped number rather than eyeballing a diameter.
Why We Would Upgrade Gauge on a Long-Term Offset
If you keep the same smoker for a decade, a heavier single-level grate from the 22-inch Weber group is likely to serve you better over that span. The swap is straightforward as long as the diameter lines up with your firebox.
12. Primo Oval XL Cast Iron Grill Grate for the Primo Oval XL 400
Primo Ceramic Grills Oval XL Cast Iron Charcoal Grate
OEM Oval XL 400 cast iron grate
3.63 kg
Part number 177807
Pros
- OEM fit for the Oval XL including 2014 models
- Holds shape far better than the original steel grate
- Easy to swap when the charcoal needs replacing
- Works with the original steel divider plate
Cons
- Arrives painted so it needs sanding or burning off first
- Divider notches cast slightly tight on some pieces
- Designed for the Oval XL 400 only
- One of the higher priced grates in the guide
The Oval is one of the harder cookers in this guide to find a correct part for, and this is the factory answer. It is designed specifically for the Primo Oval XL 400 and works with the original steel divider plate, including plates that are fifteen years old.
Durability is where this part stands out. Owners replacing original steel grates report this cast iron piece does not warp, and the Oval’s ceramic body holds steady temperature once the grate is properly preheated, so the two work together well.
Two practical notes before first use. The grate arrives painted, so sandblast it or burn the paint off outside before you season it, and a few pieces have divider notches cast slightly too tight for the steel plate, which takes light grinding to clear.
Best Cast Iron Grill Grate for Primo Oval XL 400 Owners
Nothing else in this guide fits the Oval, and searching for a cross-brand substitute is a losing use of time given the unusual oval footprint. This is the part, with 164 reviews behind it and a 4.8 average.
Why This One Ranks Despite a Small Review Base
Because it is an OEM component for a cooker where no aftermarket alternative is credible. A 164-review average of 4.8 with 89 percent five-star is strong evidence for a part nobody else is making.
Are Cast Iron Grill Grates Actually Better Than Stainless Steel?
They are better for searing and worse for smoke contact, and both statements are true at the same time. The answer depends on what you are cooking and how much the thermal mass matters to you.
What Makes Cast Iron Grill Grates Different From Stainless Steel Grates?
Thermal mass is the whole difference. A cast iron grate absorbs heat during a long preheat and becomes its own heat source, radiating that stored energy back into the food. A thin stainless grid heats almost instantly and then follows the charcoal’s temperature up and down.
That means a cast iron grate takes five to ten minutes longer to preheat, and then keeps cooking at temperature after the coals have burned down. Stainless gives you fast response to airflow changes. Cast iron gives you a stable cooking surface when the fire is dying.
Why Cast Iron Grates Block Smoke Flavor and How Rod Spacing Fixes It
The objection is legitimate. Thick cast iron rods have less open area between them than thin steel bars, so less smoke passes through to contact the food surface directly. Deep grill marks do not automatically mean more flavor, and a tight cast iron pattern genuinely reduces direct smoke contact.
Rod spacing fixes most of it. Grates with a raised inner sear insert and visible gaps between rods let more smoke through in the open sections, and any grate with vertical gaps or a split layout performs better on smoke than a fully solid single plane. If smoke contact is your priority, the two-level systems here are a better compromise than the single-level plates.
Bare Cast Iron vs Porcelain-Enameled Cast Iron: Which Is Better for Charcoal?
For a charcoal grill, bare cast iron wins on durability because there is no coating to chip. The classic failure mode is an enamel layer that cracks from thermal shock or from being dropped, and the moment it breaks, bare iron underneath starts rusting and there is no way to repair the coating.
Coated cast iron, like the Aura grate in this guide, wins on convenience. It arrives non-stick, needs no seasoning routine, and cleans with soap and water. The Aura grate’s cracking complaints also show the other risk: coated cast iron that fails, fails completely, because there is no repair path once the coating is gone.
Stainless steel grates sit in the middle on maintenance and lose on heat retention. If you already own good cast iron cookware, our cast iron cookware guide covers the seasoning habits that carry over to a grate.
How to Choose the Right Cast Iron Grill Grate for Your Charcoal Grill
Fitment decides everything else. Get the diameter and the model number right, and the rest of the decision is about rod spacing, weight, and how much maintenance you want to own.
What Size Cast Iron Grill Grate Fits a Weber Kettle or 22-Inch Charcoal Grill?
Most 22-inch and 22.5-inch Weber bowls take a 21.5-inch round cast iron grate with a 12-inch inner grid. The 22-inch One-Touch, Master-Touch, Bar-B-Kettle, Performer, Performer Deluxe, and Original Kettle Premium are all covered by the parts in this guide.
For kamados it is diameter driven: 15.5 inches for a medium Big Green Egg, 18 inches round for a Large Big Green Egg or Kamado Joe Classic, and 19.5 to 19.75 inches for the Char-Griller Akorn family. Barrel and offset smokers use rectangular bars instead, and a one-pack grates a round bowl while a four-pack grates a barrel.
How to Measure Your Charcoal Grill Grate Before You Buy a Replacement
Lift the old grate out and measure across the widest point of the cooking circle, not the bowl. Then measure the inner grid opening separately, because that is the second number sellers get wrong on listings.
Next, find your model number. It is stamped on a tag under the lid, on the cart leg, or on a label inside the firebox on kamados and offsets. Cross-reference that against the fit list on the listing rather than trusting the product photos, since the photos are frequently reused across variants.
Why Heavy Cast Iron Grill Grates Are Worth It for High-Heat Steak Sear Marks
Grill marks come from two things: contact time and grate temperature. A thin steel grid cannot get hot enough to darken a steak surface quickly because it is absorbing energy as fast as the fire delivers it. Cast iron stores enough energy to reach searing temperature and hold it there through the contact.
The other benefit nobody mentions is recovery. On a cast iron grate you can sear a second steak ten minutes after the coals have visibly faded, which is not possible on a thin grid that has already given its heat back to the air.
Which Cast Iron Grill Grate Is Easiest to Clean and Maintain?
Coated cast iron is the least effort, and the Gcostar and GGC grates are the best examples in this guide. Soap, a soft brush, and a thin coat of oil is the whole routine, and neither one needs a full seasoning cycle to stop food sticking.
For bare cast iron the routine is scraper, stiff brush, thin oil, and dry. That is a five-minute job after most cooks. The trap is leaving it wet or uncovered overnight, and cast iron that sits damp between sessions will show orange bloom by morning.
If you are still building out a kit, the grill accessories we use cover the brushes and scrapers that make either material easier to live with.
How to Season a New Cast Iron Grill Grate So It Does Not Stick
Seasoning is a polymerized oil film, not a coating you can scrub off. It builds in thin layers, and each layer needs heat to cure before the next one goes on. Rushing it is the single most common reason a new grate still sticks.
What Type of Oil Is Best for Seasoning a Cast Iron Grill Grate?
Flax seed oil is the best choice for the first seasoning because it actually polymerizes into a hard, slightly flexible film. Bacon grease, lard, and shortening work, and plenty of owners use them happily, but they are not as durable and they need more frequent refreshing.
Regular vegetable oil with a high smoke point is the safe middle option. Whichever you pick, the rule is the same: an almost invisible layer, wiped on with a paper towel until the grate looks dry, because pooled oil becomes sticky gum rather than seasoning.
How to Season a New Cast Iron Grill Grate Step by Step
Start by removing all factory oils with hot water, dish soap, and a scrubber, then dry it completely on a burner or in an oven. Any residue that stays behind becomes part of your first layer and causes flaking later.
Run the grill at its highest setting with the grate installed, wait fifteen minutes, turn it off, and let the grate cool until it is handleable. Repeat that heat cycle once before you ever add oil, because the goal is to burn off the manufacturing residue first.
Wipe on a paper-thin coat of oil, put the grate back over indirect heat away from the coals for an hour, wipe off anything that has not absorbed, and repeat. Two or three cycles give you a usable surface, and five or six give you one that stops being a project.
How to Stop a Cast Iron Grill Grate From Rusting Between Cooks
Oil after every single cook, while the grate is still warm. That is the entire routine, and it takes about a minute. Wipe it, leave it to dry fully, and only then cover or store it.
Store it under cover, not in a damp shed and not wrapped in a wet towel. For a grill that lives outside, a fitted cover matters more than any oil brand, and for kamado grates keep them off the ceramic rim where condensation collects.
How to Remove Surface Rust From a Cast Iron Grill Grate
Surface rust is a seasoning starting point, not a defect. New cast iron grates frequently show orange bloom in the box, and owners who return them for it are returning a part that would have seasoned out on the first two cooks.
Scrub it with a wire brush or coarse steel wool, rinse, dry completely, then re-season as described above. If rust pits the surface rather than sitting on it, the grate has been wet too long and the coating needs more work, but the metal underneath is still sound in almost every case.
Frequently Asked Questions
What are the best grates for a charcoal grill?
For searing, cast iron grill grates are the best choice because they store heat and radiate it back into the food, producing deeper marks and holding temperature after coals burn down. For smoke flavor and fast heat response, thin stainless steel remains better because more smoke passes between the rods. Most owners pair a cast iron cooking grid with a plated steel fuel grate underneath.
Are cast iron grill grates better?
Cast iron grill grates are better for searing, heat retention, and durability, and they cost you in weight, heat-up time, and a seasoning routine. They also block more smoke than thin steel because the rods sit closer together. Whether that is an improvement depends on whether you sear more than you smoke.
Can I use a cast iron grate on a charcoal grill?
Yes, cast iron grates are designed for charcoal grills and are standard equipment on kamados like the Big Green Egg and Kamado Joe. Install a cast iron cooking grid above a fuel grate, not in place of one, so charcoal stays lifted above the vents and airflow is maintained.
What type of oil is best for seasoning cast iron grill grates?
Flax seed oil is best for a first seasoning because it polymerizes into a hard, durable film. Bacon grease, lard, and shortening also work but need more frequent refreshing. Any high smoke point oil works if you wipe on a paper-thin layer and wipe off the excess before heating.
What is the best way to get rust off cast iron grill grates?
Scrub light surface rust with a wire brush or coarse steel wool, rinse with water, dry the grate completely, then re-season it. Surface rust on a new grate is normal and not a defect. Deep pitting means the grate stayed wet too long, and the coating needs rebuilding rather than just scrubbing.
Is it safe to cook on a rusted grill grate?
Light surface rust on a cast iron grate is not a safety problem once it is scrubbed and re-seasoned. The real concerns are structural: a cracked, thinned, or flaking grate can break and should be replaced. Deep pitting, rust flakes in your food, or a grate that wobbles on its rack all mean replace it.
Our Final Pick From the Best Cast Iron Grill Grates for Charcoal Grills in 2026
The Weber 7441 factory grate is our first pick, with 4867 reviews behind it and an exact fit for the widest range of 22-inch bowls, and it is the foundation every cast iron cooking grid in this guide sits on. For an 18-inch kamado, the Kamado Joe half-moon grate is the OEM answer with a 655-review record and a three-year warranty behind it.
Measure first, buy second. A cast iron grill grate is a model-specific part, and the one thing that decides whether you are happy is whether it sits flat on the rack. Once that is right, season it properly, oil it after every cook, and it will outlast the grill it came from.
