I have galvanized, corrugated roofing for the ceiling of my basement and wanted to mount 4' LED lights to it but didn't want to drill a bunch of holes that might miss the studs. I made these LED clips to mount the lights and also to be movable since they're magnetic. The 12mm x 3mm magnets are glued into the clip using super glue or epoxy.
Here are the roof/ceiling panels: https://www.lowes.com/pd/Union-Corrugating-2-16-ft-x-8-ft-Corrugated-Metal-Roof-Panel/3317582
These are the LED lights that I'm using: https://www.amazon.com/dp/B076FQ15R6
These 12mm x 3mm magnets are strong enough to easily hold up the lights: https://www.amazon.com/dp/B07DD5SLLJ
