The only round steel forms I have seen are two piece ones, with each semicircle having flanges, bolted together.

No, I don't design forms, just the concrete that goes in the forms.

Google “round concrete column forms”, they are made of various materials, paper (cardboard), steel, fiberglas, etc. The later two are usually rented and are reusable. Obviously, you could design your own forms, but why would you? They are basically a round tube resisting internal hydrostatic pressure from the wet concrete. The reinforcing cage is usually set in place and then the forms are installed around it.
