Get a hand shear, you’ll be glad you did. That’s what they are designed for and it works great.

Will those cut through the raised ribs?
They sure will. I use them on r-panel roofing when skinning doors for dumpster enclosures.
I think harbor freight sells them for about 20 or 30 dollars.
I have cut panels every way you can think of. There is no comparison imo.
