Uniflasy 17 Inches Cooking Grates for Home Depot Nexgrill 720-0830H 720-0830D, 720-0783E, 720-0783C Gas Grill Replacement Parts, Stainless Steel Uniflame Gas Grills Cooking Grids 2 Pack

Why I swapped my grill grates and what changed

I’ve always believed you can breathe new life into a tired gas grill with the right set of grates. After a couple seasons of babying thinning, flaking grids on my backyard workhorse, I swapped them for a pair of Uniflasy stainless grill grates. The difference has been immediate: cleaner sear marks, fewer flare-ups, and far less maintenance anxiety.

These are a two-piece set, each grate measuring 17 x 13.2 inches (for a total 17 x 26.4), built from solid 7 mm stainless rods. They’re designed for several four- and five-burner models—most notably Nexgrill units like the 720-0830H/0830D series and the 720-0888 five-burner—as well as the Cuisinart CGG-7400. I used them on a four-burner Nexgrill, and the fit was spot-on.

Fit and installation

Installation took about 30 seconds: lift out the old, drop in the new. The edges sit flush on the ledges, no rocking, no binding. If you’ve ever fought grates that were shy a quarter inch or sat crooked, you’ll appreciate a proper fit.

A quick note on sizing: the dimensions here are exact. Measure your existing grates (length, width, and the ledge depth they rest on) before you order. Grill model lineups change frequently at big box stores, and what “almost” fits is usually an expensive headache.

Build and materials

The build quality is what sold me. The rods are thick (7 mm) and evenly spaced with tighter gaps than many OEM grids. That narrower spacing matters: shrimp, asparagus tips, and smaller veg no longer swan-dive through the grate. Welds are clean and consistent, and the frame rails don’t flex under pressure.

Uniflasy uses a non-magnetic stainless steel here. My magnet test didn’t stick, which usually signals an austenitic stainless grade with better corrosion resistance. The rods are truly solid, not hollow. In hand, the pair has substantial weight without being unwieldy.

There are small edge cutouts along both sides that conveniently leave access to the burner area. If your electronic ignition ever acts up, you can manually light the burners with a long lighter through those openings without pulling the grates off. It’s a small design touch that saves time.

Heat performance and searing

Heat-up time is a shade quicker than my old cast iron grates, and recovery after lifting the lid is noticeably better. Stainless doesn’t retain heat quite the way cast iron does, but the 7 mm rods make up a lot of that difference. After a 10–12 minute preheat on high, I’m getting bold, even sear marks and a well-rendered crust on steaks and chops.

• Steaks: Strong crosshatch, minimal sticking once the grates are properly hot and lightly oiled.
• Burgers: Even browning without blowtorch flare-ups, thanks to the tighter spacing limiting fat drop-through.
• Fish and veg: With a thin oil coat on the protein and the grate, I’ve had no tear-away on salmon and halibut. Asparagus, scallions, and sliced peppers stay put.

I also noticed better distribution at the edges than with my old setup, which had cool spots over the perimeter rails. These spread heat more uniformly across the cooking surface, making two-zone setups more predictable.

Day-to-day cooking experience

The immediate quality-of-life improvement has been food control. The narrower rod spacing keeps smaller items safe, and the thicker bars anchor food better when using a spatula or tongs—less sliding around, more precise flips. The grates don’t ring or flex when moving heavier cuts, and they sit square even after multiple high-heat cooks.

I haven’t experienced any warping, even after a 20-minute high-heat burn-off cycle. If you do a lot of high-temp pizza or cast-iron pan work on your grill, these will hold up.

Cleaning and maintenance

If you’re coming from cast iron, you’ll appreciate the simplicity. I brush these while they’re hot, then wipe with a damp cloth. Most residue releases easily because the stainless surface is smoother and doesn’t build up seasoning layers in the same way as cast iron.

A few maintenance tips that have worked well for me:
- Preheat thoroughly and oil the food (not the grates) to reduce sticking.
- Use a good quality bristle-free brush or a coiled stainless scrubber; avoid cheap wire brushes that shed.
- For occasional deep cleaning, a mild stainless cleaner or a baking soda paste lifts stubborn carbon without scouring the metal.
- Let the grates dry after rain or a wash; stainless resists rust, but water spots and “tea staining” can occur in humid or coastal environments.

After several months outdoors, mine show the expected straw and blue heat tinting, plus light surface discoloration near the burners—normal for stainless. No pitting or flaking.

Durability

Solid stainless construction is the main draw. There’s no porcelain coating to chip, and no brittle casting to split. Stainless can show surface oxidation over time, but it doesn’t behave like the rust bloom you get on neglected cast iron. I’m seeing the kind of cosmetic patina that comes with use, not structural degradation.

One caveat: salt-heavy marinades and winter storage in damp climates will accelerate discoloration on any stainless. Rinse the grates after very salty cooks and keep the lid closed with a cover on during the off-season. It’s basic care that will prolong their life.

Compatibility and sizing notes

On my Nexgrill 720-0830H, these were a perfect fit. They’re also specced for several other Nexgrill four- and five-burner models and the Cuisinart CGG-7400. If you’re at the margins on width, remember you’ve got two panels—there’s no lateral play once they’re seated. Replacing “almost-right” grates with the correct 17 x 13.2 each is the difference between a satisfying drop-in and a weekend of grinding tabs.

If you need heavier mass or a different cooking feel, Uniflasy does make cast iron options for some models, but for my use (weeknight cooking and mixed protein/veg), stainless is the better balance of performance and maintenance.

Value

The pair costs less than many OEM replacements while stepping up to thicker, solid stainless rods. Considering how much more forgiving stainless is to maintain—and how it avoids the porcelain-chipping problem common on budget grates—the price-to-longevity ratio is strong. More rods than typical OEM pieces and tighter spacing add functional value beyond just material upgrade.

What could be better

• Stainless isn’t magic: you can still see surface staining with heavy use, especially if the grill lives outdoors year-round. It’s cosmetic, but worth noting.
• If you’re a cast-iron purist chasing maximum thermal mass and that old-school, blackened seasoning layer, these won’t feel identical. The sear is excellent, but the flavor contribution of a seasoned cast iron grate is its own thing.
• Measure twice. Grill model numbers can be confusing, and a few millimeters off in ledge width can spoil the party.

The bottom line

Swapping to these Uniflasy stainless grill grates has made my gas grill more enjoyable to cook on and far easier to maintain. The 7 mm solid rods deliver confident sear marks and even heat across the surface. The tighter spacing solves the small-food-falling-through problem without resorting to a basket for everything. Cleanup is quick, and the non-magnetic stainless has held up beautifully through repeated high-heat cooks.

Recommendation: I recommend these grates for anyone with a compatible Nexgrill or Cuisinart model who wants a durable, low-maintenance upgrade that improves searing and control. They hit the practical sweet spot: substantial build, smart spacing, straightforward care, and a fair price. If you grill often and are tired of tending to finicky cast iron or flaky porcelain-coated grids, this is an easy, worthwhile improvement. Measure your existing grates to confirm fit, drop them in, and cook.
