I don't think I've seen corrugated cladding made from it. Ours is usually zincalume (dipped in zomc/aluminium) or cplourbond - baked on coating that lasts forever.
Our roof is made of galvalume (according to Google, it's the same thing as zincalume). Came with a 40 year warranty and I'll believe it lasts forever, but the green color sure faded badly in the New Mexican sun in the past 13 years. (Granted, at 7000 ft, we're closer to the sun than some folks....)
