A sheetmetal fabricator would have a slip-roller which they'd use to roll the radius into sheetmetal.
Short of that,you might find pre-fabricated flue pipe for a gas-fired water heater of appropriate diameter,which could be cut down to create the soft edges.
The inside surface of PVC pipe can also be used as a mold to layup fiberglass radius sections.I did this for a trailer body."joggles" can be cast into mating edges of the part by taping chipboard strips inside the mold with aluminum tape.
Three coats of carnauba wax will get a clean release from the mold.
