The sparks from an angle grinder have nothing to do with the heat. Two potential problems have been discussed - heat development and sparks.D daugaard said:If it gets so hot that sparks fly from the reciprocating saw, then you're probably doing something wrong.
I also advise against cutting with an angle grinder/disc grinder!
I honestly don't understand what you're getting at. The thread is about a reasonable way to cut several painted corrugated sheets at the same time. The recommendations from different manufacturers have surely already been read by TS. If one strictly read and followed recommendations from the current manufacturer, I wouldn't even be able to do my job.S sixten88 said:
I want to explain that one should not cut coated sheet metal with an angle grinder because it damages the sheet.
No matter how skilled you are with the angle grinder.
Then I have given the original poster an alternative to cut the sheets in a bundle with a plunge saw.

Hello everyone, and thanks for an engaging discussion!
I am well aware of how one SHOULD do it, but I was looking to save some time since it’s just about the roof of a pretty run-down tool shed. It is built against an existing building, and the roof extends under the eaves of the other building by about 0.5m, so the half-meter closest to the cut will neither be visible nor heavily impacted by moisture.
So for me, it wasn't the end of the world if the sheets were slightly damaged, so I ended up using an angle grinder. Attaching some pictures. Despite clamps and protection for the top sheet, I noticed quite a bit of shavings got between the sheets, so if you're concerned about the sheets, I wouldn't recommend the method. But in my case, I'm satisfied!
