One thing you can do is to preserve the factory edge for the down side.

A second option is to use a carbide blade in a skill saw (I hope they use
this term in OZ) and sandwich the material between the corrugated wood to
minimize deflection. This will still leave a burr, but that can be removed
by careful scraping.

Other options you may wish to consider are a different roofing material such
as a plastic material or using asphalt shingles. What are you putting a
roof on?

I'd like to cut corrugated roofing steel, and get a nice clean edge like
from the factory.
All I can manage is a nasty jagged edge, either with snips or angle
grinder. The roof is low, and I don't want the hazardous edge.

Q: Can corrugated sheet be neatly cut by shears/guillotine?

Other?

Thanks
