Uniflasy Grill Grates Replacement — 3-Piece Cast Iron Set for Dyna-Glo Models, Even Heat & Superior Sear

Uniflasy replacement cast iron grates restore even heat, superior searing, and durable cooking surfaces for compatible Dyna-Glo and similar gas grills.

If your original grill bars are warped, flaking, or no longer delivering crisp sear marks, this Uniflasy replacement set is built to bring performance back. Engineered to match the footprint of multiple Dyna-Glo 4- and 5-burner models and a range of other compatible grills, the set includes one diamond-shaped cast-iron grate and two standard cast-iron cooking grates, so you can replace the worn parts quickly and get back to grilling.

Which grill models will these grates fit?

These grates are designed to fit specific Dyna-Glo models and many compatible makes, matching the factory mounting points and overall dimensions. Always compare measurements or original part numbers before ordering to ensure a correct fit.

How do these cast iron grates improve cooking?

Cast iron is prized for its heat retention and ability to create defined sear marks — qualities that raise the visual and flavor appeal of grilled food. These grates heat evenly across the surface, helping maintain stable temperatures when searing steaks, vegetables, or seafood.

• Excellent heat retention produces stronger, more consistent sears
• Even heat distribution minimizes cold spots across the cooking surface
• Durable surface resists chipping compared with thinner enamel-coated bars
• Diamond grate profile offers a different sear pattern and food release

What’s included and how do I install them?

The package ships with one diamond cast-iron grate plus two straight cast-iron cooking grates, matching the original replacement part numbers for quick swap-in. Installation is straightforward: remove the old grates, position the new grates into the support channels, and ensure they sit level before use.

• Package contents: 1 diamond grate + 2 cast iron cooking grates
• Original part cross-references supplied to verify compatibility
• Fits into existing grate supports without permanent modification
• Inspect fit and alignment before lighting the grill

How do I maintain cast iron grates to prevent rust?

Cast iron requires simple upkeep to stay rust-free and nonstick: clean off food debris after each cook, lightly oil the surfaces, and avoid prolonged exposure to moisture. Following a few routine steps will prolong the life of the grates and keep them performing at their best.

• Scrape residual food after every use while warm
• Season by brushing with a thin layer of cooking oil after cleaning
• Keep grill dampers slightly open to reduce internal condensation
• Cover or leave the lid closed when the grill is not in use; for long storage, heavily oil and bag the grates

Who is this for: Grillers who want a heavy-duty, long-lasting replacement for worn or damaged factory bars will benefit most. This set is ideal if you own a compatible Dyna-Glo, Kenmore, Backyard, GBC, or Uniflame model and want to restore even heating, stronger sear marks, and a rugged cooking surface without replacing the entire grill. If you prefer low-maintenance, enamel-coated bars, note these are bare cast iron and need periodic seasoning to prevent rust.
