If your grill grates are rusted, chipped, or warped, your food will likely stick, and you will not get the heat you need for a good sear. The real question is which material and design will actually last through your next few seasons of cooking. This guide covers the best aftermarket cooking grid options that fit common gas and charcoal grills, explaining what each material does for your cooking and how much upkeep each one really needs.
I’m Rikta — the co-founder and writer behind FitlyFast. 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.
The best aftermarket cooking grid balances heat retention, rust resistance, and fit for your specific grill model. Whether you are replacing grates on a Weber Spirit, a Nexgrill from Home Depot, or an older Char-Griller, the right cooking grid changes how your food turns out.
How To Choose The Best Aftermarket Cooking Grid
You start with your grill model and your cooking style. Here are the key decisions to make before you buy.
Material matters more than you think
Cast iron holds heat like a brick — it stays hot even when you load on food, giving you sear marks without the grill temperature crashing. Stainless steel heats up faster and resists rust naturally, so it is easier to maintain. Porcelain-coated cast iron aims to give you the best of both, but the coating can chip over time.
Measure before you order
Grill sizes vary by brand and year. You need the exact length and width of your current grate, plus the total cooking area if you buy a two-piece set. A quarter-inch gap in the data can mean a grate that wobbles or does not fit at all.
Consider your cleaning routine
Bare cast iron needs to be dried and oiled after washing, or it rusts. Stainless steel you can scrub without worry. If you do not want to think about seasoning and oiling every time, stainless steel saves you that extra step.

In-Depth Reviews
1. SnS Grills EasySpin Charcoal Grill Cooking Grate
$79.99as of Jul 16, 8:43 AM21.5 inches across, 304 stainless steel, and a large hinged opening make this the top pick for anyone who wants to add charcoal mid-cook without moving food off the fire. It fits the Original Kettle, Performer, and MasterTouch series, with extra rails near the handles for more usable space.
Buyers report the grate is thicker and better quality than the original Weber grate, and they love the spinning mechanism for searing using the cold-grate method. The spinning action lets you rotate food closer to or away from the coals by hand — no tools or batteries needed. It is built for 2-zone cooking, so you can sear on one side and smoke on the other with the SnS basket.
The catch is the price, which is higher than basic replacement grates, but the 10-year warranty and thick 304 stainless steel construction mean you will not be replacing it next season. If you want one grate that lasts and makes your kettle more versatile, this is it.
Why it’s great
- 304 stainless steel resists rust much longer than coated grates
- Hinged opening lets you add charcoal without disturbing food
- Precision spinning for easy 2-zone cooking
Good to know
- Only fits 22-inch kettle grills — not for gas grills
- Higher upfront cost than budget grates
2. Utheer 7637 Cast Iron Grill Grates for Spirit E210 E220 S210 S220
from $31.99as of Jul 16, 8:43 AMCompared to the top-pick Htanch SG523 stainless steel grates, the Utheer 7637 cast iron set holds heat longer—its 5.8-pound thermal mass delivers sear marks without cold spots—but requires more care to avoid rust. These grates are made for Weber Spirit 200 and Spirit II 200 series grills (E210, E220, S210, S220).
Owners mention these grates fit perfectly on grills that sat in storage for years with corrosion inside. The bare cast iron needs seasoning (oiling after cleaning) to become non-stick, but customers note the grates produce great sear marks once seasoned. At 17.5 inches by 10.2 inches per grate, the pair covers the full cooking area of a Spirit 200 without gaps.
Choose the Utheer over the top pick if you have a gas Spirit grill and want cast iron’s heat retention without paying for a premium spinning grate. Just plan to dry and oil them after each cook.
Where it shines
- Heavy cast iron holds steady heat for even searing
- Available as a 2-pack for full grill coverage
- Much cheaper than buying a new grill
Worth noting
- Bare cast iron rusts if not dried and oiled after use
- Only fits front-control Spirit 200, not side-control or Spirit 300
3. Parts DC104 17inch Grill Grates for Nexgrill 4 Burner & Charbroil
$32.99as of Jul 16, 8:43 AMYou are replacing the tired, rusted grates on your Nexgrill or Charbroil 4-burner, and this drop-in set requires minimum maintenance. The porcelain-coated cast iron pair measures 17 inches by 13.25 inches per grate (total 17 inches by 26.5 inches), fitting models like the Nexgrill 720-0830H and 720-0888N, plus Charbroil 4-burner and Kenmore grills. The porcelain coating releases food without sticking, so you skip the seasoning routine that bare cast iron demands.
Reviewers point out that one grate was off in width by about a quarter inch, but it still worked and looked great on the grill. The grates handle up to 500 degrees Celsius, tolerating high-heat searing sessions. Reviewers use them weekly for smash burgers and say they kept their grills running like new after replacing old rusty parts.
The standout spec here is the 5.29-kilogram total weight—a full 6 times heavier than the 0.88-kilogram budget grate for the Go-Anywhere.
What stands out
- Porcelain coating keeps food from sticking without extra oiling
- Fits multiple Nexgrill, Charbroil, and Kenmore models
- Heavy cast iron construction (5.29 kg total) for steady heat
The trade-offs
- Porcelain can chip if dropped or scraped hard
- Width may be off by a small fraction (buyers reported 1/4 inch)
4. Grill Grates for Nexgrill Replacement Parts 5 Burner 720-0888N
$39.99$49.99as of Jul 16, 8:43 AMThe single number that matters most in this category is weight, and these matte cast iron grates score a 12.84-pound total — nearly 2.5 times heavier than the 5.29-kilogram Parts DC104 grates. That extra metal holds temperature steady even when you load on cold steaks, so the grill surface does not cool down as fast, delivering dark sear marks from heat retention.
The downside here is corrosion over time. Shoppers say that the first season was great with perfect fit and good sear marks, but by the second season the grates rusted just like the originals. The matte cast iron has no coating, so it requires the same care as bare cast iron — dry and oil it after every use to make it last beyond a single season.
If you want the best sear marks for the price and are willing to maintain bare cast iron, this set gives you the thermal mass to match. But if you prefer a set-it-and-forget-it material, the stainless steel options below need less care — making this a price-to-value read that prioritizes searing performance over low maintenance.
The upsides
- Heavy matte cast iron (12.84 lbs) for superior heat retention
- Fits Nexgrill, Expert Grill, Charbroil, Kenmore, and Cuisinart models
- Produces professional-style sear marks
Keep in mind
- Bare cast iron will rust if not seasoned and dried after each cook
- Some buyers saw rust by the second season
5. Htanch SG523 (2-Pack) 15″ Stainless Steel Cooking Grid for Weber Spirit
from $34.99as of Jul 16, 8:43 AMYou get two 15-by-11.25-inch polished stainless steel grates (84.38 square inches each) that eliminate the coating-chipping problem entirely on Weber Spirit grills. The set fits Weber Genesis Silver A, Spirit 500, Spirit E/S 200, and Spirit 210 models from 2007 to 2012. The stainless steel finish needs no seasoning or oiling, so you can scrub it clean without worrying about removing a non-stick layer.
Buyers report these grates are heavy duty and nicely welded, and they fit perfectly on old Weber Spirit grills. One reviewer had replaced original grates with cheaper ceramic-coated replacements that started flaking within 4-5 uses, and the SG523 stainless steel grates solved that problem permanently. The 84.38-square-inch cooking surface area per grate gives you enough room for a family cookout.
You trade the absolute best sear marks of cast iron for a grate that never needs oiling and will not rust. For a gas grill that lives outside, that trade-off often makes more sense, and this 2-pack is perfect for the budget buyer who wants a permanent fix for flaking grates on an older Weber Spirit.
Why we’d pick it
- Polished stainless steel resists rust and flaking
- Easy to clean — no seasoning needed
- Heavy-duty welded construction
A few caveats
- Does not retain heat as well as cast iron
- Only fits specific Weber and Kenmore models from 2007-2012
6. Votenli S6505A (4-Pack) 19 3/4″ Stainless Steel Cooking Grid for Char-Griller
$54.99as of Jul 16, 8:43 AMThis 4-pack is perfect for the Char-Griller owner who wants to cover a large 19.75-inch by 27-inch cooking area (279.94 square inches) without buying individual grates, and who prefers stainless steel’s lower maintenance over wrought iron or cast iron. It fits Char-Griller gas models 2121, 2123, 2222, 2828, 3001, 3030, 3725, 4000, 5050, 5252, and the Char-Griller Duo 5050 dual-fuel grill.
Owners mention that these grates fit perfectly and are a major upgrade over the nasty wrought iron originals. One reviewer who switched from cast iron says the stainless steel heats up faster and delivers a better sear, while the 4.74-kilogram total weight is lighter than cast iron and requires no special upkeep.
The one caution is fit: measure your existing grates before ordering, because Char-Griller models vary by year and the burners may not align if your grill is an older or less common model.
Strong points
- 4 stainless steel grates cover a large 279.94 sq in cooking area
- Heats up faster than cast iron for a quicker sear
- No rust left behind after cleaning — buyers confirm this
Before you buy
- Lower heat retention than cast iron
- Only fits specific Char-Griller and King Griller models
7. 80631 Stainless Steel Grill Grate for Weber Go-Anywhere
$21.99as of Jul 16, 8:43 AMAt just 0.88 kilograms, this grate is 6 times lighter than the 5.29-kilogram Parts DC104 grates — making it the most portable and affordable option in this guide. The stainless steel build provides more airflow than the original cast iron grate, helping the coals start faster and burn hotter with less charcoal.
What you give up at this budget level is raw thermal mass — the lighter steel does not hold heat as long as heavy cast iron, so you might see more temperature drop when you load on cold meat. Buyers confirm the fit is perfect and they cooked on it the first night, calling it a great replacement that costs far less than buying a new portable grill. The stainless steel finish makes cleanup simple, and you never need to worry about seasoning or rust.
This is the exact buyer who wants a simple, rust-resistant replacement for a Weber Go-Anywhere. It makes the grill heat up faster and costs less than a tank of gas.
What we like
- Lightweight stainless steel (0.88 kg) for portable use
- More airflow for faster coal ignition and hotter burns
- Easy to clean with no seasoning required
The downsides
- Lighter metal means less heat retention than cast iron
- Slightly smaller than the original grate (buyers confirm it still works)
Understanding the Specs
Material: Cast Iron vs Stainless Steel
Cast iron absorbs and holds heat over the whole surface, so your steaks see consistent high temperatures even after you flip them. Stainless steel heats up faster but cools down quicker when you add food. Cast iron typically needs seasoning (a thin layer of oil baked onto the surface) to become non-stick, while stainless steel is naturally less sticky and can be scrubbed without damage.
Porcelain Coating
Some cast iron grates come with a porcelain coating that prevents rust and makes food release easier without seasoning. The trade-off is that the coating can chip if you scrape it hard with a metal brush or drop the grate. Once chipped, the exposed cast iron underneath will rust if not cared for.
Weight and Heat Retention
Heavier grates (measured in pounds or kilograms) store more thermal energy. A grate that weighs 12.84 pounds will keep its temperature more stable when cold food hits it than a grate that weighs 0.88 kilograms. For searing, weight matters more than material — a heavy grate produces better crust.
Grill Fit and Dimensions
Every grill model has unique grate dimensions. The length and width are measured in inches, and some grills require a two-piece or four-piece set. Always measure your current grate from left to right and front to back, then compare those numbers to the product listing — a difference of even half an inch can mean poor fit.
