The reproduction columns are made of fiberglass, and it was actually the Friends of Cast Iron that tried to salvage many of the cast iron elements in the city. Most of these have been put into the Ankeny Arcade. (But there might be more of a reserve...)

A great out of print book to read if you're interested in the Cast Iron architecture is "The Grand Era of Cast-Iron Architecture in Portland" by William John Hawkins III.

An interesting side note, some of the cast iron detailing and stained glass from the 1881 Ladd Block can now be found on the top floor of the Umpqua Bank Building, in the courtyard, and around the elevator lobby.
