A well-used outdoor kitchen lives or dies by the parts that quietly do the heavy lifting. Heat shields, burner tubes, and grates all take the brunt of high-heat cooking, so when one corrodes or cracks, your favorite cookout turns into a flare-up mess. This roundup pulls together nine replacement options that fit popular gas grill models, so you can match the right piece to your specific rig without guessing on dimensions or compatibility.

A Deeper Look At The Lineup
Grilling season has a way of exposing worn heat shields right when you need them most, and the Utheer replacement set targets one of the most common Dyna-Glo three-burner configurations. The shields measure roughly 13.7 by 3.2 inches each, sold as a set of three to cover a full cooking chamber.
Utheer leans on heavier porcelain-coated steel than typical aftermarket plates, which matters if you tend to crank the heat for searing. Owners commonly report the added thickness holds up well under sustained high-BTU cooking without warping at the corners.
The Case For It
- Porcelain coating resists corrosion through repeated high-heat sessions
- Thicker steel than typical replacement shields for added rigidity
- Direct fit for several Dyna-Glo 3-burner model numbers, including DGC310CNP-D
- Set of three covers a full grill in one purchase
Things To Consider
- Dimensions are fixed, so measure your existing shields before ordering to confirm a match
- Porcelain can chip if you scrape aggressively during cleaning
At A Glance
Made For
Anyone running a Dyna-Glo 3-burner propane rig whose factory plates have rusted through or developed hot spots.
Consider Something Else When
Step up to the Unicook 4 Pack Adjustable Gas Grill Heat Plates if your grill is an off-brand or you cannot confirm the exact model number, since the sliding fit covers a wider length range.
Replacing one piece at a time on a Weber Genesis 300 gets old fast, and Hongso bundles both the grates and flavorizer bars in a single kit. The package includes two porcelain-coated cooking grates measuring 19.5 by 12.75 inches each, plus five flavorizer bars at 17.5 by 2.25 by 2.375 inches.
This combination targets Weber Genesis 300 models from 2011 through 2016 with front-mounted control knobs, which is a specific window worth double-checking before checkout. If you routinely sear over high heat, having fresh flavorizer bars cuts down on the flare-ups that come with rusted or warped shields.
Bright Spots
- Grates and flavorizer bars included in one kit
- Porcelain-coated steel for straightforward cleanup
- Direct fit for the 2011–2016 Genesis 300 lineup with front knobs
- Restores even heat distribution across the cooking surface
Worth Noting
- Not compatible with the Genesis II series, so check your model before ordering
- Grates arrive bare and benefit from an initial seasoning to reduce sticking
Who It Suits Best
Owners of a 2011–2016 Weber Genesis 300 with front control knobs who want to refresh both grates and shields in a single session.
Look Elsewhere When
Grab the MOASKER Prestige 500 Heat Plates and Burners Kit instead if you grill on a Napoleon Prestige 500 and need a more thorough burner-and-shield overhaul.
Grill brands come and go, but the underlying heat plate dimensions tend to repeat across multiple lineups. GasSaf leans into that pattern with a 15 by 3.8125 inch plate sold in a five-pack, covering a handful of common Backyard, Dyna-Glo, and Uniflame configurations.
The porcelain steel construction is straightforward and corrosion-resistant, which fits the needs of someone replacing a worn set without overhauling the entire grill. You may find the five-piece count handy if one plate has already failed and the others are likely not far behind.
A Strong Showing
- Five plates in one package, enough for a full replacement plus a spare
- Corrosion-resistant porcelain steel for longer service life
- Works across multiple brand families, simplifying stocking up
- Standard 15-inch length fits several popular model numbers
Trade Offs
- Fixed dimensions mean you must measure existing plates first
- More plates than you may need if you only own a 2-burner model
Built With In Mind
Anyone juggling multiple grills from the Backyard, Dyna-Glo, or Uniflame families who wants a single replacement source.
A Better Fit Elsewhere
Pick the Utheer Grill Parts Heat Plates instead for a thinner, dedicated three-pack designed specifically for Dyna-Glo 3-burner configurations.
Walmart’s Expert Grill line is everywhere, but factory replacement plates can be hit or miss at the local store. BBQration fills that gap with a three-pack sized at roughly 11.625 by 2.75 inches, targeting the XG10-101-002-02 and GBC2016WRS model numbers.
The set comes in at a compact footprint, which suits a 3-burner cabinet without crowding the burner tubes. Porcelain steel construction keeps cleanup manageable, especially if you cook often enough that grease accumulates faster than you would like.
Points In Its Favor
- Direct fit for the widely owned Expert Grill XG10-101-002-02
- Compact dimensions suit a smaller 3-burner cabinet
- Porcelain coating wipes down with basic grill cleaner
- Three-pack covers a complete replacement
Points To Keep In Mind
- Smaller plate size means it will not cross over to larger 4 or 5-burner cabinets
- Aftermarket fit can vary slightly from OEM plates, so dry-fit before lighting
Right Fit For
Expert Grill 3-burner owners who want a wallet-friendly refresh without hunting for OEM replacements.
Swap It Out When
Move up to the Unicook 14.6 Inch Grill Heat Plates 3 Pack if you own a Nexgrill or Kenmore with a wider burner span.
Heat plates live a hard life above open flames, and Unicook addresses that with a thicker 20-gauge build at 14.6 by 4.2 inches per piece. The three-pack targets popular Nexgrill and Kenmore burner configurations, including several Home Depot Nexgrill model numbers.
Thicker steel resists the warping that thinner plates suffer through repeated high-BTU searing, and the porcelain finish keeps food drippings from sticking. You may find this set useful if your existing plates have started sagging toward the burners.
Key Advantages
- 20-gauge steel for added rigidity over typical replacements
- Wider 4.2-inch depth shields burners more thoroughly
- Cross-compatible with Nexgrill, Kenmore, and several Home Depot models
- Three-pack covers most 2 to 4-burner cabinets in one purchase
Minor Gripes
- Deeper profile may not fit shallow hood clearances on compact grills
- Requires checking exact burner spacing, since some 5-burner models need a longer plate
Best Suited To
Nexgrill or Kenmore owners who push their grills hard and want thicker shields that resist sagging over time.
Reach For A Different Pick When
Turn to the GasSaf 15 inch Heat Plate Replacement 5-Pack if you need extra plates as spares or you own a Backyard or Uniflame model.
When the burner tubes rust through, no amount of new heat plates will save a cookout. Fenluqi offers a cast stainless steel replacement in a four-pack, designed for Bull grills but also compatible with Blaze, Cal Flame, Lion, and several other premium brands.
Cast stainless handles the thermal cycling that warps cheaper stamped steel, so this set works for both natural gas and propane configurations. The 4-pack quantity suits larger 4 and 5-burner outdoor kitchens where downtime from a single failed burner can derail a weekend gathering.
What Pays Off
- Cast stainless steel resists corrosion far longer than standard tubes
- Works with both natural gas and propane setups
- Broad brand compatibility including Bull, Blaze, and Cal Flame
- Four-pack covers full-size grills without leaving a burner mismatched
Some Limits To Know
- Heavier weight may require extra care during installation
- Higher price tier than basic stamped replacements, though longevity offsets that over time
Perfect Match For
Premium grill owners rebuilding a Bull, Blaze, or similar rig whose original burner tubes have finally given out.
Another Choice May Suit
Choose the MOASKER Stainless Steel Heat Plates and Burners Set instead if your setup is a Napoleon Rogue or Prestige 500.
Sometimes you do not know the exact grill model, and a sliding-fit plate solves that puzzle. Unicook’s adjustable heat plates telescope from 11.75 up to 21 inches, giving you enough range to cover Char-Broil, Nexgrill, and other mid-size cabinets.
The 3.75-inch width sits in a comfortable middle ground, and reversing the install extends the range from 11.75 to 18.37 inches for narrower setups. For anyone dealing with a hand-me-down grill and no paperwork, this flexibility removes a lot of guesswork.
Well-Handled Touches
- Telescoping design covers a wide length range in a single product
- Reversible install adds another length option for tighter cabinets
- Compatible with popular Char-Broil and Nexgrill models
- Four plates handle a full replacement in one purchase
Honest Caveats
- Measure the mounting slot width first, since the 3.75-inch profile only fits certain brackets
- Adjustable joints can collect grease over time and need occasional cleaning
Who Should Grab It
Anyone with an unknown or hard-to-source grill brand who needs a flexible-fit plate without committing to a model-specific part.
Skip It When
You prefer the BBQration Heat Plates for Expert Grill 3-Burner, which offer a direct fit if you know your model is an Expert Grill.
Napoleon Prestige 500 owners know that a full refresh requires both new plates and new burner tubes, and MOASKER packages both. The kit includes seven porcelain steel heat plates and a stainless burner, replacing OEM part numbers N305-0082 for plates and N100-0044 for the burner.
This set covers a long list of Prestige 500 variants, including P500PSSRB, P500RSIBPK-3, and BIP500RBPSS-3. Anyone whose grill has uneven heating or rust-through on either component gets a one-shot solution.
Where It Delivers
- Combines plates and burner in one kit for a complete refresh
- Porcelain steel plates paired with stainless burner for balanced durability
- Matches numerous Prestige 500 model numbers
- Replaces specific OEM part numbers for a closer factory fit
Small Caveats
- Single burner replacement means you may want to confirm whether all four need swapping
- Cross-checking the model number list takes a few extra minutes before checkout
Whose Shelf It Belongs On
Napoleon Prestige 500 owners ready to commit to a deeper overhaul rather than swapping parts one at a time.
Where A Sibling Pick Shines
The MOASKER Stainless Steel Heat Plates and Burners Set goes further with a full four-burner stainless rebuild for Rogue series grills.
For Napoleon Rogue and Prestige 500 grills pushed hard through long summer seasons, stainless steel components outlast porcelain by a wide margin. MOASKER’s premium set includes seven sear plates at 16.125 by 3.5 inches each, plus four burner tubes at 17 inches long.
The full stainless build targets the same N305-0082 plates and N100-0044 burner replacements covered in the porcelain kit earlier, so anyone weighing material choice has a clear comparison. You may find the upfront cost easier to justify if you cook outdoors year-round rather than seasonally.
Benefits That Matter
- Full stainless construction outlasts porcelain in harsh weather
- Four burner tubes included for a complete Rogue rebuild
- Matches both Rogue series and Prestige 500 propane configurations
- Sear plate dimensions verified against common OEM sizes
Areas To Watch
- Stainless can discolor under extreme heat, though this is purely cosmetic
- Heavier than the porcelain equivalent, so plan extra time for installation
Who Will Love This
Napoleon Rogue owners who want the longest service life from their rebuild and cook frequently enough to justify the stainless upgrade.
Not Your Match When
The MOASKER Prestige 500 Heat Plates and Burners Kit is a better value if you only need to replace one burner and prefer the lighter porcelain plates.
What To Weigh Before Buying Replacement Grill Parts
Match The Model Number First
Compatibility drives everything in this category. A heat plate that is off by even a quarter inch can leave a burner exposed or refuse to seat in the mounting slot. Before anything else, pull up the model number on your grill’s frame (often on a tag under the lid or on the back panel) and cross-check it against the product listing. If your grill came with paperwork, the model number is usually printed there too.
Choose The Right Material For Your Climate
Porcelain-coated steel is the most common replacement material and handles typical backyard use well, but the coating can chip if scraped during cleaning. Cast stainless steel costs more and adds weight, yet it shrugs off weather cycles that destroy thinner plates in coastal or humid regions. For occasional grilling in mild climates, porcelain is plenty. For year-round outdoor setups or premium grills, stainless pays back over time.
Decide Between Single-Piece And Combo Kits
If only one component has failed, a single replacement is the obvious move. When multiple parts show rust or uneven heating, a combo kit saves on shipping and ensures matched dimensions across the cooking chamber. The MOASKER kits earlier in the lineup show how bundled sets simplify a full overhaul without guesswork on part sizing.
Mind The Dimensions, Not Just The Brand
Universal-fit plates are useful when you cannot identify the model, but they only work if the length range covers your burner span. Sliding plates like the Unicook adjustable set cover a wide window, yet they still demand a correct width measurement. A quick tape check of your existing plates prevents the hassle of returns and reorders.
Key Considerations Across These Picks
Pitfalls Shoppers Hit
The most common mistake is trusting a brand name on the listing without confirming the model number. Cross-listed compatibility lists help, yet slight variations between sub-models mean a plate that fits one Dyna-Glo configuration may not fit another. Another trap is overlooking the mounting style. Some plates slot into brackets while others rest on support rails, and buying the wrong style means drilling or fabricating work you did not plan for. Always dry-fit new plates before lighting the grill for the first time.
Where The Extra Money Goes
Premium kits like the MOASKER stainless set cost more because the material itself is pricier and the manufacturing tolerance is tighter. Cast stainless burner tubes last several seasons longer than stamped alternatives, which spreads the cost across many cookouts. For most backyard cooks, mid-tier porcelain plates deliver solid service. The upgrade makes sense once you start losing sleep over rust streaks on every meal or replacing the same component every other summer.
Frequently Asked Questions
How do I find my grill’s model number?
Look for a metal tag or sticker under the control panel, on the back of the cabinet, or inside the door of the storage cart. The tag typically lists the brand, model, and serial number in a small block of text.
Can I mix heat plate brands on the same grill?
Yes, as long as the dimensions match your existing mounting slots. Plates from different manufacturers work side by side without issue when the length and width line up correctly.
How often should heat plates be replaced?
Most plates last two to five seasons depending on use frequency, cleaning habits, and exposure to weather. Visible rust-through, warping toward the burners, or persistent hot spots signal it is time for a swap.
Are stainless steel parts worth the higher cost?
Stainless costs more upfront but resists corrosion far longer than porcelain-coated steel, making it a smart pick for grills stored outdoors or used year-round. Casual seasonal users often find porcelain sufficient.
Do replacement burners affect cooking performance?
New burner tubes restore even flame distribution and proper heat output, which directly improves searing and reduces cold zones on the grates. A failing burner can cause uneven cooking regardless of how fresh the plates are.
Closing Remarks
Replacing worn components breathes new life into a tired grill without the cost of a full replacement. The right part comes down to knowing your model number, measuring carefully, and choosing materials that match how often you cook. With the options above, you can handle anything from a single rusty plate to a full premium stainless overhaul.
