Mine did not have any protection. I purchased it about 1995. I sprayed cold
galvanization on it. It's been out in wx since then. Some rust stains where I
scratched galv during install. No noticeable rust stains on my shingles,
however my shingles are brown.

Not sure, but if you buy 4130, doesn't it usually come without any protection,
like galvanization?

The problem with most sources is that shipping is the killer.
As someone said, under a certain length (108 inches aka 9ft) it can go UPS,
over, you are looking at truck.
What we call CrMo DOM mast is more commonly referred to as 4130 tube. If you
have a ‘local’ steel supplier, there is a good chance they either have it, or
can get it fairly easily, and you may be able to pick it up. (Assuming you have
a truck), or they might be willing to do a delivery (expect to pay). If you
have a local machine shop, or user of steel, you might be able to sweet talk
them into ordering the material on their next shipment, and the delivery gets
lumped in. Hint, your 90-200 lbs of mast (3” .250 wall, about 7.75 lbs/ft,
smaller diameters less) doesn’t mean much when they are getting 3+ tons of
steel delivered.
