This is a sidewalk grip where it ramps up from the street. I noticed that all of them have the same melt pattern. Low traffic area when no one was out.
Just curious if anyone knows why

Here is what the underside of that particular plate looks like. The metal heats up faster than the concrete as the temperature rises, so the parts with thicker metal melt faster.
Wow, a lot people knew the answer. You even managed to find an image.
Mind blown.
Thanks everyone!
Yep, Lemmy is a pretty neat place!
It’s pretty much my favorite so far.
