Nicole R.★★★☆☆October 24, 2012
Decent, but a bit pricey

Definitely solid 304 stainless and they fit my 28 inch 3 burner perfectly. For the price though, I hoped they'd hold heat or sear noticeably better. They do the job, it's just a lot to spend on replacement grates.

Riley A.★★★★★March 6, 2026
Grill feels new again

Big difference. My old grates were a mess, and these 3/8 inch solid stainless ones make my 28 inch grill feel brand new. Cooks more evenly and cleanup is easy. Recommend.

Pam C.★★★☆☆June 14, 2022
Good quality, but heavy

No question these are quality, they feel really sturdy. Fit my 28 inch grill like it said. Only complaint is they're pretty heavy, so they're a bit awkward to take out and clean, especially hot.

Brooke S.★★★★☆September 24, 2018
Solid upgrade

I've had my 28 inch Sunstone grill for years and it was time for new grates. These 3/8 inch 304 stainless ones are a big step up from the originals. They heat up well and leave nice sear marks. Good way to keep the grill going longer.

Dan T.★★★★☆October 27, 2025
Great fit

Exactly what I needed for my 28 inch grill. Good 304 stainless and the 3/8 inch thickness feels substantial. Dropped right in and my steaks are coming off with a nice char. Very happy.

Q
My 28 inch grill is a different brand. Will these grates fit?Asked by Sunstone Support Team
A
They're made for the Sunstone 28" 3 burner grill. Some other 28 inch grills may have similar dimensions, but we can't guarantee they'll fit. Measure your current grates or check your grill's manual and compare before you buy.

Q
How do I clean these grates?Asked by Sunstone Support Team
A
Heat up the grill and scrape off food with a good stainless grill brush after each use. For a deeper clean, wash them with warm soapy water and a non abrasive sponge and rinse well. Make sure they're dry before you store them so you don't get water spots.

Q
Are these 3/8 inch 304 stainless grates really better than cheaper ones?Asked by Sunstone Support Team
A
Yes. The 3/8" thickness holds heat better, so you get better searing and more even cooking. 304 stainless resists rust and corrosion, so these last a lot longer outdoors than chrome plated or thinner steel grates.

Q
How hard is it to put these grates in my 28 inch 3 burner grill? Any tools needed?Asked by Sunstone Support Team
A
Really easy. Take out the old grates and drop these 3/8" 304 stainless grates in. You normally don't need any tools.
