GrillGrates warped after several years

[Le Grill]

Anyone else experience this warping? I've had these GGs for ~5 years and I use my grill a couple times per week. I'm surprised to see they warped so much over time. I often put a 12" Lodge cast iron directly on the grates, possibly the extra weight contributed to this?

Anyway, swapped back to the factory SS grates for now, my old hand down Weber Genesis Silver B is still going!!

Looks like its time for some new Grill Grates

I’ve had this happen but I attributed it to too much heat. I did find them pretty easy to bend back but the structural integrity feels like it has changed.

I tried putting them upside down on the grill while on warp 10 heat with a heavy cast iron pan on top, doesn't seem to want to bend back to flat for me

Le Grill oh wow! Maybe try a towel and some vice grips? Maybe a rubber mallet and towel?

Weird. I replaced the OEM grates on my Genny B with GrillGrates at least 5 years ago and use the grill a lot, and they haven't warped. I didn't think that the old girl can get hot enough to warp them, which is one of the reasons that I got 'em.

I have the half moon set for one of my kettles that do get blazing hot, but they haven't warped yet. I do, however, take the precaution of rotating the grate away from the heat afterwards on the kettle.

I think that the combo of heat and the CI pan contributed to this.

A quick look at GrillGrate.com's FAQ says this about putting a pan on top of their grates:

"We do not recommend you put anything on your GrillGrates other than food or our GrateGriddle. Heat can potentially become trapped and damage the GrillGrates."

I presume from this that they can and do warp if they get too hot.

Thanks for pointing that out, makes sense.
