My local lumber yard supplied us with PT LVLs when we did a pedestrian bridge. They usually have access to the mfg engineers and can calculate the spans & sizes.
I used an old barn beam (untreated) on my porch roof. Not a problem as it never gets wet, but once in a while we get a boring insect(see/wasp) that likes to make holes.
