Bob - Since it is a new gate you had built, can you ask the supplier
what they recommend? I'd start with your favorite cleaner/degreaser
then use a phosphoric acid "metal prep" product. I did this on a second
hand roll bar that was a bit rusty then sprayed with an epoxy paint.Â
Still looks good after 20+ years.
Here is a sample product that looks like what I used:

or

Note that if the iron was galvanized, you have different directions.Â
Here is one of the search returns on painting galvanized metal:
