I have a similar topic in another forum, but thought a different angle question would be better here:
What kind of spans can a 6X12 beam cover?
I have an opportunity to get a 100 or so fir 6X12s that are 23 feet long for $40 each. They came out of an old shopping mall being torn down. Don't know if that's a good deal or not, but this question is more to the application? For that length, are they way oversized???
