macomber-canton joist tables
i am trying to find load tables for an old joist.  i need to check the joists to ensure they are structurally adequate for a new roof top unit.
the tags state they are macomber-canton joists.  i found an old structural engineering topics thread dated 2003.  it appears some members have tables.  if anyone can help me i would greatly appreciate it.
a member did post a link to a bethel steel pdf that would have been helpful, but the link is no longer working since the company went out of business.
thank you
