I’ve often wondered about the slight roundover used on all four edges on the length of framing lumber. Is it only to make it look good, more comfortable, or create fewer splinters? There must be a more serious reason for this edge treatment. Can anyone explain this point of trivia?
Carol Reed: Dimension lumber suffers much automated handling, from milling to stacking into a banded unit that is loaded unto train cars or truck. The rounded over edges makes that handling easier and delivers a better-looking product to the end user.
