I'm having my front porch rebuilt, including new columns. The current
ones are wooden, round and tapered (maybe 8" or 10"). Because our
house is sort of Arts and Crafts style, we think we want to go with
box columns. The porch bears the load of our second-floor dormer. What
are the pros and cons of the various materials used for columns? Each
contractor seems to have different ideas about the various materials
(steel, fiberglass, wood, aluminum, etc.). Thanks!
