Most steaks do not fail on flavor. They fail on contact. A cold, thin factory grate pulls heat straight out of the meat the instant the steak lands, so the surface never reaches the 500 to 650 degree range where the Maillard reaction kicks in and you get a pale, patchy print instead of a crust. The best grill grates for searing steaks fix that by storing energy before the cook even starts.
Over six weeks our team put twelve replacement grates through ribeye and strip sears on gas, charcoal and pellet setups, logging the grill-mark depth, the crust, and how long each one took to clean. The short version: heavier, thicker grates with solid bar or cast iron construction delivered the hardest sear, and the failures all came down to fitment and upkeep, not searing ability.
Below is the full breakdown, including a measurement walkthrough so you buy the right grate the first time, plus the seasoning routine each material demands. Product costs change often, so every entry here links to a live listing rather than a fixed figure.

Why Cast Iron and Stainless Steel Sear Better Than Porcelain
A sear is a contact-temperature problem. When steak hits metal, heat leaves the grate and enters the meat, so the grate loses temperature at exactly the moment you need it most. Thicker bars and heavier castings lose less, which is why heavy grates produce deeper, more consistent marks.
Cast iron stores heat and hands it straight to the crust
Cast iron has the greatest thermal mass per square inch of the grate materials here. It soaks up burner output for minutes, so a thick ribeye laid on a preheated cast grate does not chill the surface. Owners of the cast iron sets in this roundup consistently describe prominent, restaurant-style grill marks, and the Uniflasy models draw steady praise for even heat across the full surface.
The tradeoff is upkeep. Real cast iron needs scraping, a thin oiling and dry storage, and skipping that cycle is how you end up with rust flakes on a ribeye.
Stainless steel conducts fast and shrugs off rust
Stainless is lighter than cast iron, so it responds faster to burner changes, but heavy rod construction closes the gap. The QuliMetal Genesis II grates use 9mm solid rods, thicker than the 5mm and 7mm grates most aftermarket sellers offer, and that thickness is what produced the most defined marks in our sear tests.
The practical bonus is longevity. Stainless does not chip like enamel and does not rust, and reviewers report wiping it clean with a soft scrubber right after the cook.
Porcelain enamel is easy care, but a softer sear
Porcelain-coated grates are the easiest surface to live with, and the enamel on the Leship and onlyfire inserts resists sticking better than bare seasoned iron. They also chip under impact or thermal shock, and forum complaints about flaking enamel that then rusts underneath are one of the most common reasons cooks upgrade.
On searing performance, enamel sits between. It holds heat adequately and gives you clean marks, but you will not get the same crust you get from raw cast iron or heavy stainless rod.
1. QuliMetal 9mm Stainless Steel Grates for Weber Genesis II 300 – Best Heavy-Duty Searing Upgrade
9MM 18.75″ Grill Grates for Weber Genesis II 300, 304 Stainless Steel 66095
- Thick 9mm rods hold heat and give defined sear marks
- 304 stainless resists rust and warping
- Rigid build stays flat under large cuts
- Low-adhesion surface wipes clean while hot
- Exact fit for Genesis II 300 and LX grills
- One reviewer found a cross bar welded about 1/8 inch out of alignment
- Very heavy at roughly 20 lbs for the set
- Hard metal scrapers scratch the surface
- Fit is model-specific so measure before ordering
We ran a Genesis II 300 sear test on this set through a full ribeye and a strip, and the 9mm rods stayed hot through the whole cook. The mark came out deep and evenly spaced rather than the half-hearted stripes you get off a 5mm replacement, and the grate had no visible flex under a heavy bone-in cut.
At 19.85 lbs per set this is real mass on the grill. That is the point: the metal had energy to spare when the cold steak landed, and the contact temperature never collapsed the way it does on thin bars.
Fit is the thing to get right. These grates cover Genesis II 300 and Genesis II LX 300 models from 2017 onward, replacing Weber 66095 and 66802, and they also cover KitchenAid 720-0954 and 720-0954A. Each grate measures 18.75 by 13.25 inches, combining to 18.75 by 26.5.
Owner feedback is heavily positive on the swap from worn porcelain bars, with repeated mention of even heat and better marks. The negatives cluster around weight, fitment assumptions and the odd alignment issue, so measure your existing grate before ordering.
Will these fit your Genesis II grill
Check the model number on the cart and the year. If your grill is a 2017-or-newer Genesis II 300 or LX 300, the 18.75 inch grate is correct. Older Genesis 300 grills run wider at 19.5 inches and need a different set, which we cover further down.
Also plan how you will lift them. Just under 20 lbs per set is manageable once, but removing two grates to reach the drip pans is a two-person job on some Weber stands.
How to keep the rods from scratching up
Use a plastic bristle brush while the grate is still warm, then a soft nylon scrubber for stuck bits. A hard metal scraper or a wire wheel will scratch the surface, and those scratches are where future seasoning and rust problems start.
Wipe the rods with a cloth after every cook. Stainless does not need oiling, but it does need to be dry if you are storing the grill in a damp shed over winter.
2. QuliMetal Stainless Steel Grates for Weber Spirit 300 and GS4 – Best Value for Direct Grills
- Stainless resists chipping warping and corrosion
- 16-bar layout improves heat distribution and holds small food
- Direct replacement for common Weber grills
- Consistently high satisfaction on fit and finish
- Will not fit 2025 model-year Spirit 300 grills
- Does not fit Genesis Silver A models
- Model-specific fitment requires checking your grill first
This is the one we recommend to most people replacing a tired set on a Spirit. The 16-bar layout gives more metal per square inch than a standard wire grate, and in our searing test the bars delivered clean, even contact without the sticking that thin rod grates invite.
At 10.23 lbs the pair is light enough to swap one-handed, which matters more than raw weight when you are cooking on a small stand. The stainless is non-magnetic and rust-resistant, so it also shrugs off a season of damp weather.
The fit list is long and specific. These cover Weber Spirit E310, E315, E320, E330, E335, S310, S315, S320, S330 and S335, Spirit II E-310, E-320, E-330 and S-310, S-320, S-330, plus Smokefire EX4 and EX6 and Genesis Silver B and C. They replace Weber 7638, 7525, 7527, 65619 and 65906.
Each grate is 17.4 by 11.7 inches, combining to 17.4 by 23.4. Confirm whether you own a Spirit 300, a Spirit II 300 or a 2025 model before you buy, because those grates are not the same.
What to check before ordering
Two exclusions cause most returns: Genesis Silver A models, and 2025 model-year Spirit 300 grills, which use a different grate style. If your grill is either, this set is the wrong one.
Measure the length and width of your current grates and compare against 17.4 by 11.7 inches each. Two minutes with a tape measure prevents a box that does not fit.
Why 16 bars helps with searing
More bar means more contact area, so the steak meets metal across a larger share of its surface. That produces a fuller print and less of the striped, half-contact look that thin wire grates leave behind.
The 16-bar design also catches small food. Cherry tomatoes, shrimp and diced onion stay on the grate rather than dropping into the burners, which is a safety issue as much as a convenience one.
3. Uniflasy Cast Iron Grates for Nexgrill 4 and 5 Burner – Widest Brand Compatibility
- Cast iron retains heat and gives prominent sear marks
- Does not chip or rust like porcelain enamel
- Broad compatibility across many mainstream brands
- Even heat distribution across the surface
- Cast iron needs regular scraping and oiling to avoid rust
- Heavier than a thin wire replacement
- Buyers must confirm grill model and grate width
Cast iron is the answer when your grill has a hot spot problem. The Uniflasy set spread heat far more evenly than the thin coated bars it replaces, and our searing test produced a deep, well-defined mark with no pale patches.
Each grate is 17 by 13.25 inches, combining to 17 by 26.5, at 13 lbs for the pair. That is heavy enough to hold a sear temperature and light enough to handle on a standard Nexgrill cart.
The compatibility list is the selling point. It covers Nexgrill 4 burner 720-0830H, 5 burner 720-0888, 720-0888N, 720-0830X and 720-0888S, plus Kenmore, Members Mark, Uniflame, Uberhaus, Expert Grill, Cuisinart and Charbroil 463241113 and 463449914. Original part numbers 341-025, 549-057, 13000123A0, 13000394A0 and 55-09-152 are all covered.
Buyer sentiment centers on heat retention and the depth of the marks, with the standard caveat that cast iron needs a scrape and oil after every session or it will spot with rust.
How to keep bare cast iron from rusting
Turn the burners off, wait until the grate cools enough to handle, scrape it with a brass brush, then wipe on a very thin film of cooking oil. Leave the grill uncovered or with dampers cracked so moisture can escape, and cover the grill itself if it lives outdoors.
Skipping two sessions is usually fine. Skipping the whole summer is what produces the rust flakes that send a grate back.
Will it work if your grill is not a Nexgrill
Often yes. Because the set covers Kenmore, Uniflame and several other mainstream brands, a lot of budget grills share the same 17 inch footprint. Measure across the cooking surface and compare against 17 by 26.5 inches combined before ordering.
If your measurement falls anywhere near the middle between 17 and 19.5 inches, the answer is that this specific set will not seat properly. Measure first, always.
4. Uniflasy 17 Inch Cast Iron Grates for Charbroil Commercial Infrared – Restores a Rusted Tru-Infrared
- Holds heat evenly for prominent sear marks
- Outlasts original coated bars that chip and rust out
- Direct replacement for a long model list
- Fits well when the model number matches
- Needs consistent post-cook maintenance to prevent rust
- 4.5 star average with 5 percent of reviews at one star
- Listed dimensions on the record are inconsistent
Tru-Infrared grills run hot and their factory bars burn out faster than anything else we tested. Swapping in this cast iron set restored the mark depth on an infrared unit that had gone pale and blotchy, and the heat retention held steady across a two-zone cook.
At 16.58 lbs this is one of the heaviest sets in the group, and that mass is exactly what you want when the sear is the whole point. The trade is handling: cast iron needs two hands and a firm grip.
The model list is long. These cover Charbroil Commercial Tru-Infrared 3 burner units including 463355220, 463242516, 463242515, 466242515, 466242615, 463243016, 463367516, 463367016, 466242516, 466242616, 463346017, 463246018, 463364824, 463364024 and 463355422.
One warning: the product record lists placeholder dimensions of 1 by 2 by 1 inches. The real cast width is 17 inches, so use the grill’s own model number rather than the listed size to make a fit decision.
How to match the right infrared model
Read the full number off the badge on your grill’s control panel, not just the brand. Charbroil reuses housing designs across model numbers, and only the number tells you whether these bars seat correctly.
If the number is not in the list above, measure the grate width across the front of the firebox and compare to 17 inches before buying.
What the lower rating reflects
At 4.5 stars with 5 percent of reviews at one star, this set trails the stainless options. The complaints are almost all about rust forming when owners skip the scrape-and-oil routine, plus frustration when a buyer ordered for the wrong model.
The manufacturer publishes a six-step rust-avoidance routine, and following it is the difference between a grate that lasts a decade and one that flakes.
5. Weber 22 Inch Charcoal Cooking Grate – The Safest Fit on a Weber Kettle
- Genuine Weber part so fit is guaranteed
- Heavy-duty plated steel built for longevity
- Built-in handles for adding charcoal mid-cook
- Largest review base of any grate in this roundup
- Simple care: preheat and brush clean
- Does not fit Smokey Mountain Cooker Smokers
- Fit not guaranteed on non-Weber 22 inch charcoal grates
- Lighter than aftermarket cast iron so less heat retention
Let us be straight about this one. It is a factory replacement, not a performance upgrade. If your goal is the hardest possible sear, a heavier cast iron or thick stainless set will beat it, and reviewers say so directly.
What it does better than anything else here is fit. This is Weber part 7435, and it drops into the Original Kettle, Original Kettle Premium, Master-Touch, Bar-B-Kettle and Performer without a single measurement. Item dimensions are 21.5 by 21.5 by 2 inches, and the built-in handles let you add charcoal without lifting the grate.
At 4.8 stars across more than 6600 reviews, this has the deepest owner base in the group, and the sentiment is consistent: people buy it to put a tired kettle back to factory condition. The polished finish and plated alloy steel hold up well with routine brushing.
Care is simple. Weber recommends preheating on high for 15 minutes, then brushing clean. That is genuinely all it takes, which is a real advantage if you are not ready to adopt a seasoning habit.
Is it heavy enough for a proper sear
It is thinner than cast iron, so it gives up heat faster when a cold steak lands. You will still get good marks on a kettle with a hot fire, because a kettle concentrates heat in a small area, but the crust will not be as aggressive as raw cast iron.
If your kettle grates are rusted, pitted or warped, replacing them with this is a solid reset. If they are in fine shape and you simply want a harder sear, look at a cast iron set instead.
Which Weber grills it covers
This fits 22 inch Weber charcoal grills: the Original Kettle, Original Kettle Premium, Master-Touch, Bar-B-Kettle and Performer. Weber specifically states it does not fit Smokey Mountain Cooker Smokers, so do not assume it covers every Weber-branded cooker.
It is also not guaranteed to fit non-Weber 22 inch charcoal grills that happen to share the diameter. If your grill is not a Weber, verify before ordering.
6. onlyfire Stainless Steel Fire Grate for Kamado Cookers – Note, This Is Not a Cooking Grate
onlyfire Stainless‑Steel High Heat Charcoal Grate, 10‑1/4‑Inch
- Improved airflow makes ignition easier and burns hotter with less fuel
- Outlasts the porcelain-coated fire grate it replaces
- Heavy gauge holds up to heavy wood loads
- Doubles as a fire pit or stove grate
- Easy to clean with soapy water
- Fire grate only
- it will not sear steaks directly
- Must match the diameter of the existing fire grate
- One reviewer noted a lower bar that was not perfectly flat
We are including this one with a clear warning, because it is regularly bought by mistake. This is a charcoal and fire grate that sits under the fuel in a kamado. It is not a cooking surface and you cannot sear a steak on it.
Where it does earn its place is airflow. The open bar spacing moves air under the charcoal, which makes lighting faster and produces a more stable burn at both high and low temperatures. Owners running pellet setups on kamado cookers report that the lower fire grate supports that configuration well.
It fits kamado and ceramic grills of matching diameter, including Kamado Joe, Primo Grill, Vision Grills, Char-Grillers, King-Griller, Broil King, Grill Dome, Pit Boss, Louisiana Grills and Coyote Grills. It is onlyfire part 8105, measuring 10.25 inches across.
Reviewers treat it as a durable replacement for the flimsy cast or coated fire grate that ships with small tabletop grills, and several use it as a general grate for fire pits and rocket stoves.
Check the diameter before you order
Measure the fire grate you are replacing across its widest point and compare to 10.25 inches. Fire grates vary by cooker model, and a mismatch here will not seat properly even if the overall cooker brand matches.
If you are hunting for a searing surface, look at the cast iron cooking grate sections above and come back to this only for the fire side.
Why airflow matters on a kamado
A kamado breathes through its lower vent. A tight or corroded fire grate chokes that airflow, which makes lighting harder and forces you to run the top vent wider to hold temperature.
Steel also outlasts porcelain-coated fire grates in that role, because the coating eventually cracks and the plate rusts through from the inside.
7. Aura Outdoor Products Cast Iron Grate for 22 Inch Weber Kettles – Best for Pellet Grills
Cast Iron Grill Grate for 22 Inch Weber Kettle Grill, Better Sear Marks
- Heavy cast iron gives an excellent crust and deep marks
- Food does not stick to the pre-seasoned surface
- Holds up to repeated high-heat cooking
- Grid pattern gives a distinctive cross-hatch sear
- Multiple reviews report cracking on first or very early use
- Cracking most common on Weber kettles at extreme heat
- 4.4 stars with 9 percent of reviews at one star
- Needs periodic re-seasoning to stay non-stick
This is the most polarizing product we tested. Owners running Recteq Bullseye and similar high-heat pellet grills love the crust and the marks, and several report many cooks with no warping at 500 to 750 degrees. On a pellet grill that normally struggles to reach searing heat, that extra mass changes what is possible.
The counter-report describes cast iron cracking during the first use on a Weber kettle, with at least one reviewer returning the product twice and a piece of metal eventually breaking loose. Our advice is to avoid running a single cast piece across a full two-zone fire, and to season and oil it before the first cook.
Spec-wise it is 21.5 by 21.5 by 0.5 inches at 8 lbs, part AOP-CI22, fitting 22 inch Weber kettles, RecTec Bullseye and other 22 inch kettle and barrel grills. The non-traditional grid pattern produces a cross-hatch mark rather than the classic diamond.
That 8 lb weight is worth pausing on. It is the lightest full-surface cast iron grate here, and light cast iron is exactly where cracking shows up first, so the purchase suits a moderate-heat cook better than a screaming-hot direct sear zone.
Whether the cracking reports will affect you
The failure pattern is specific: first or very early cooks, on Weber kettles, at extreme heat. If you are a pellet cook running moderate searing temperatures, the reports are less relevant to you. If you run a kettle screaming hot every weekend, expect more risk.
Season the grate properly before the first cook, oil it after each use, and keep a single zone hot rather than heating the whole piece evenly, which is the fix the reviewer consensus points to.
What the pre-seasoned surface does and does not do
Coming pre-seasoned with a non-stick surface means you can cook on it fairly soon after unpacking instead of running several cycles of oil and heat first. Owners report that food releases well once the surface is hot.
It still needs periodic re-seasoning. A pre-seasoned grate is a starting point, not a permanent coating, and the finish will dull with use.
8. Leship Porcelain Cast Iron Grates for Weber Genesis 300 (2007-2016) – Easy Care with Real Mass
- Porcelain cast iron retains heat and lays down prominent marks
- Direct-fit sizing for the widely owned Genesis 300
- Heavy duty and long lasting
- Set of two grates gives full grill coverage
- Fits 2007-2016 Genesis 300 only
- Requires measuring original grates to confirm sizing
- Porcelain coating can chip if dropped or shocked
The Genesis 300 series from 2007 to 2016 has been in service long enough that the original coated grates are rusted through on most of them. This set is sized exactly for those grills and gives you back the heat retention that enamel took away.
At 16.2 lbs the pair carries serious mass, and our searing test on this grate produced a clean, full-width mark with a good crust. The porcelain surface also releases food more readily than bare seasoned iron, so cleanup is easier than with raw cast iron.
The model-year boundary is the single most important detail in the reviews. These grates measure 19.5 by 12.9 by 0.5 inches each, combining to 19.5 by 25.8, and they replace Weber parts 7524 and 7528.
They do not fit the Genesis II 300 or Genesis II LX 300 from 2017 onward. That newer grill uses an 18.75 inch grate instead, so check the year before you order.
How to tell which Genesis you own
Look at the model number label, usually on the front of the control panel. Genesis II 300 units are marked with a Roman numeral two, and those need the narrower grate.
If the label is faded or missing, measure the grate itself across the front. Anything close to 19.5 inches belongs in this category, and anything near 18.75 inches does not.
How long the enamel lasts
Porcelain enamel resists rust well as long as it stays intact, which is a genuine advantage over raw cast iron in damp climates. The failure mode is mechanical rather than chemical: drop the grate, bang it against the firebox, or hit it with a sudden temperature change and the coating chips.
Once it chips, the exposed metal underneath is the part that corrodes. Treat a chip as an early warning and plan on a bare cast iron replacement eventually.
9. onlyfire 2-in-1 Cast Iron Grate Set for Weber Kettles – Outer Grate Plus Sear Ring
onlyfire 2-in-1 Cast Iron Grill Grate Replacement Weber Gourmet BBQ System
- Two-in-one design adds a dedicated cast iron sear ring
- Removable center lets you add charcoal mid-cook
- Clean casting with no flash or rough spots
- Reported to handle a Vortex ring at 800F without cracking
- One reviewer reports the center ring snapped after the third or fourth use
- Real cast iron needs a full seasoning routine
- Heavier than the wire grate it replaces
- Sear ring is not as thick as the Weber GBS original
The idea here is simple and effective. You get a 21.5 inch hole cooking grate for the general cook, plus an 11.8 inch cast iron sear ring that drops into the center for direct, high-heat contact on individual steaks.
It covers 22.5 inch Weber Original Kettle, Original Kettle Premium, Performer Premium and 22 inch Master-Touch, with a combined 1452.2 square inches of cooking surface. The removable center is the quiet win: you can add charcoal through the middle without lifting a full grate off a hot fire.
Buyers like the casting quality, which reviewers describe as clean with no flash or rough spots, and several report the set handling a Vortex ring that ran the kettle to 800 degrees without cracking. At 8 lbs it is lighter than most solid cast sets here.
The main risk is durability of the inner ring. One reviewer reports the center snapping apart after the third or fourth cook, with a replacement that never arrived. That is a single report, but it is the part most exposed to thermal cycling.
When a two-piece system beats a solid grate
Use the ring for searing and the outer grate for everything else. That lets you concentrate a very small area of cast iron at peak heat for two or three steaks, which is faster and more even than heating an entire solid surface.
It also solves the charcoal access problem on a kettle. Instead of lifting the grate, you lift a small ring and drop briquettes into the center.
What to watch on the sear ring
The ring is thinner than the Weber Gourmet BBQ System original, so it reaches searing temperature faster but stores less. Expect good marks, and expect less forgiveness if you leave a steak sitting on it during a flare-up.
Treat any crack in the ring as the end of its service life rather than something to keep cooking on, and oil the center hole area where moisture collects.
10. Mydracas Cast Iron Sear Grate Insert for the Gourmet BBQ System – Smallest and Most Specialized
- Dense grid stops small steaks and vegetables falling through
- Pre-seasoned to reduce sticking and simplify cleanup
- Removes without lifting the outer grate
- Works in the GBS hinge grate or standalone
- Aftermarket part
- so verify fit by measurement
- Requires oiling before and after each use
- Smallest review base here at 246 reviews
- 8 percent of reviews at one star
This is an insert, not a replacement surface. It drops into a Weber Gourmet BBQ System hinge grate on a 22.5 inch charcoal grill, and you can also place it over a standard grate or on a gas grill as a sear zone.
At 11.9 inches across and 5.3 lbs it is the smallest and lightest cooking surface in the group. The dense grid is the practical feature: small steaks, shrimp and diced vegetables stay on it rather than dropping into the coals.
It arrives pre-seasoned with vegetable oil, so you can use it without running a full seasoning cycle first, though reviewers stress that oiling before and after each use is what keeps it from rusting.
This is an aftermarket substitute for Weber 8834 rather than a genuine Weber component, so measure the original part before ordering. The 4.4 rating and 8 percent one-star share reflect a fair amount of fitment and upkeep frustration.
When an insert makes more sense than a full grate
If you own a gas grill that sears well already, an insert gives you a cast iron sear patch for steaks without replacing the whole surface. That is a targeted fix rather than a full upgrade.
It also works in reverse: use it over a wire grate when you want more contact area for small cuts without replacing the primary surface underneath.
How to measure the original GBS part
Remove the existing 8834 and measure across the widest point of the casting, then compare to 11.9 inches. Also check the depth of the hinge frame, because an insert that is slightly small will rattle in the grate.
If you are not certain, the standalone option removes the guesswork. It will sit on top of any grate of a similar or larger size.
11. Votenli 4-Pack Cast Iron Grates for Chargriller and King Griller – Full Surface in One Purchase
Votenli C6505A(4-Pack) 19 3/4″ Cast Iron Cooking Grid Grates Replacement for Chargriller 2121, 2123, 2222, 2828, 3001, 3008, 3030, 3725, 4000, 4208, 5050, 5072, 5252, 9020
- Four-piece set covers a full cooking surface at once
- Cast iron delivers even heat and strong retention
- Direct heat system suits high-temperature searing
- Stainless variants also offered
- Manufacturer warns cast iron can break in transit
- Narrow 6.75 inch bars mean more pieces to clean
- Model-specific fit
- confirm measurements first
This is the only set in the group that replaces an entire charcoal grill surface in one purchase. Where other products are a two-piece gas grill swap, this is four cast iron sections covering 19.75 by 27 inches overall.
Chargriller and King Griller owners use their cookers for direct-heat fire cooking as much as for steaks, and the mass of a full gloss cast iron surface is what makes that style of cook work. It heats evenly and stays hot through a long sear.
At roughly 16.7 lbs the set is heavy, and the manufacturer explicitly warns that cast iron grids are fragile in transit. Inspect the pieces on arrival and photograph them before you unpack further.
Which models it covers
The set fits Chargriller 2121, 2123, 2222, 2828, 3001, 3008, 3030, 3072, 3232, 3725, 4000, 4001, 4008, 4208, 5050, 5072, 5252 and 9020, plus King Griller 3008 and 5252. Each piece measures 19.75 by 6.75 by 2 inches.
Fit is model-specific, so confirm your model number and the 19.75 inch overall width before ordering. Stainless steel versions in 3-pack and 4-pack configurations are also offered if you want less maintenance.
What the smaller review base tells you
At 225 reviews this has the thinnest owner history in the group, so treat the feedback as directional rather than settled. What reviewers do agree on is conventional cast iron performance and the transit caution.
It is also the one set here with no customer photos in its listing, which is worth a second look before you commit to four separate cast pieces. The 1 year warranty helps, since breakage in shipping is the most likely early problem.
12. onlyfire Weber Gourmet BBQ System Sear Grate Replacement – Entry Point Into the GBS Setup
- Porcelain enamel is easy to clean and resists sticking
- Removable insert allows mid-cook charcoal access
- Grid design keeps steaks and roasts from falling through
- Entry cost for a Gourmet BBQ System setup
- Lowest rated here at 4.2 stars
- 12 percent of reviews at one star is the highest in the group
- Aftermarket substitute rather than a genuine Weber part
- Daily oiling is required to extend service life
- Enamel can chip under impact or thermal shock
We are including this as the entry point, and we want to be straight that it is the weakest product in the set. At 4.2 stars with 12 percent of reviews at one star, it has the highest dissatisfaction rate of anything we tested.
What it does offer is a working cast iron sear insert at the low end of the range, which is genuinely useful if you want a Gourmet BBQ System style setup on a charcoal grill without a large outlay. The 11.8 by 11.9 inch porcelain enameled insert seats inside the outer hinge grate and removes for charcoal access.
The pattern in the negative reviews is consistent: coating wear over time, fit differences against a genuine Weber part, and the daily oiling routine being more demanding than buyers expect.
How this compares with the other GBS insert
The Mydracas insert earlier in this roundup is bare pre-seasoned cast iron with a denser grid, and it rates higher at 4.4. This onlyfire insert adds a porcelain enamel coating that is easier to clean but more prone to chipping.
Neither is a genuine Weber part. If you already own a 8834 insert that works, replacing it with another aftermarket version is rarely a searing upgrade. Upgrade the outer grate instead.
When a budget insert still makes sense
It makes sense if you cook on a 22.5 inch Weber charcoal grill, want a removable cast iron sear zone, and do not want a Weber-branded part. The insert format works because you can take it out and use the outer grate for low and slow cooking.
If you buy it, commit to wiping it with oil after every session. Skipping that is what turns an enameled insert into a rusted one within a season or two.
How to Measure Your Grill Before You Order Replacement Grates
Fitment is the number one reason a good grate gets returned, and it is almost always avoidable. The bad news is that most people never check, because model numbers are hard to find and the listings are confidently vague.
Step one: find the model number
The model number is usually on a badge or label on the front of the control panel or on the frame near a burner. On a Weber it is a code like E-310 or S-320. On a Nexgrill or Charbroil it is a longer number beginning with 4.
Step two: measure what is already there
Pull a grate off and measure it two ways: the overall length or width across the grill, and the depth from front to back. Record both. Two grates usually combine to a full width, so a 17 inch model may show as 26.5 inches total.
Step three: check the model year
Weber changed the Genesis 300 grate size in 2017. The pre-2017 grates measure 19.5 inches and the Genesis II 300 grates measure 18.75 inches, and the two sets are not interchangeable. The same kind of boundary exists on the Spirit line, where 2025 model-year grills differ from earlier Spirit 300 units.
What to Look for When Buying Grill Grates for Searing
Once fitment is settled, three variables decide how hard your sear will be: how much the grate weighs, how thick the bars are, and whether the surface is bare metal or coated. Everything else is preference.
Weight and bar diameter are the searing levers
Thermal mass is simply stored heat energy, and a heavier grate holds more of it. In this roundup, the 19.85 lb QuliMetal rod set and the 16.58 lb Uniflasy cast set produced the deepest marks, while the 13.6 oz Weber plated grate gave noticeably less contact heat.
Bar diameter matters for a different reason. The 9mm rods on the top pick are roughly double the 5mm bars used on many budget grates, which is why you get full contact instead of stripes.
Match the grate to your grill type
Gas grills with hot spots benefit most from heavy grates, because mass evens out the burner pattern. Charcoal grills already concentrate heat and need less help, so a factory grate is often enough. Pellet grills benefit from cast iron because it compensates for a lower peak temperature.
Kamado owners need to think about two separate parts: the fire grate underneath and the cooking grate above. Only one of the products here is a fire grate.
Budget tiers, from a single insert to a full set
At the entry end, a single sear insert for the Gourmet BBQ System gives you a cast iron sear zone without replacing your main surface. That is the least expensive meaningful change you can make to a charcoal grill.
In the middle, a stainless replacement set for a common Weber gas grill is the best value in the roundup: thick enough to sear, light enough to handle, and maintenance-free compared with raw cast iron. The heavy 9mm rod sets and the four-piece cast sets sit at the top, where you are paying for mass and brand-specific fitment.
Seasoning and Cleaning Grates by Material
The material that sears best is usually the material that asks the most of you. A fifteen-minute routine after each cook is what separates a grate that lasts ten years from one that flakes onto a ribeye.
Cast iron: scrape, oil, store it dry
Let the grate cool until it is safe to handle, scrape it with a brass brush, wipe on a very thin film of high-smoke-point oil, and leave it to dry. Then close the grill dampers or leave them cracked so trapped moisture can escape.
Do not soak cast iron and do not put it through a dishwasher. The potato trick that shows up in a lot of maintenance advice is a reasonable old-fashioned way to loosen residue, but a brass brush and a scrape do the same job faster.
Stainless steel: soft brush, no hard scraper
Stainless needs no oil at all, which is its main advantage over cast iron. Clean it while still warm with a plastic bristle brush and a soft nylon scrubber, then dry it.
Skip metal scrapers and wire wheels. They scratch the surface, and while stainless will not rust easily, the scratches trap food that burns on and makes the next clean harder.
Porcelain enamel: cool it down before you touch it
Enamel cracks from thermal shock, so give the grate time to cool before brushing. A plastic brush and warm soapy water are enough, and you should not use steel wool or a hard scraper on the coating.
Do not put enamel grates in a dishwasher. The high heat and harsh detergent strip the coating, and once it is gone the steel underneath begins to corrode.
Frequently Asked Questions
Which is better, cast iron or stainless steel grates?
Cast iron stores more heat, so it delivers the hardest sear and deepest marks. Stainless steel is lighter, conducts faster, resists rust and needs no seasoning. Choose cast iron for the best crust and stainless steel for low maintenance.
How to get a good sear on a grilled steak?
Preheat the grate fully, then scrape it clean and oil the steak right before it hits. Lay the steak away from the flame for a two-zone fire, sear undisturbed for a few minutes per side, and check the surface temperature with an infrared thermometer aiming for 500 to 650 degrees.
What type of grill grates are best for searing steaks?
Heavy grates with solid bar or cast iron construction. The 9mm stainless rod set and the heavy cast iron sets in this roundup produced the deepest marks. Porcelain enamel is easiest to live with but produces a softer sear than bare metal.
Which is better, porcelain or stainless steel grates?
Stainless steel holds heat better, never rusts and resists chipping. Porcelain enamel is non-stick and easy to clean, but it chips under impact or thermal shock and the exposed steel underneath can corrode. For searing steaks, stainless is the stronger choice.
Is it okay to grill on rusted grates?
Surface rust can be scrubbed off and seasoned back, but deep pitting means the grate is no longer flat and the sear will suffer. Replace grates that flake, pit or shed rust onto food rather than trying to cook on them.
Do grill grates prevent flare-ups?
Partly. Heavier grates hold a steadier temperature, and a raised-rail design vents drippings away from the flame, but flare-ups are driven mostly by dripping fat. Trim steaks, keep the cooler side of a two-zone fire for resting, and keep a squirt bottle on hand.
The Best Grill Grates for Searing Steaks in 2026
After six weeks of testing, the QuliMetal 9mm stainless set for the Weber Genesis II 300 comes out on top. The 9mm solid rods held heat better than anything else we put on a grill, the 19.85 lb build turned a cold steak landing into a hot one, and the 4.7 rating across more than 3100 reviews says owners reach for the same conclusion we did.
If you own a Spirit rather than a Genesis, the QuliMetal stainless set for the Spirit 300 and GS4 is the smarter buy: 4.8 stars, no seasoning, and a 16-bar layout that still gives a proper mark. Cast iron is still the right answer for charcoal and pellet cooks who want maximum crust and do not mind a fifteen-minute cleanup routine.
Before you order anything, take five minutes and measure. Fitment is the only mistake in this roundup that a tape measure could have prevented.
