I went to Home Depot this AM to buy lumber. Their stuff always used to have grade stamps on it, but today the 2x6 x 8' and 2x4 x 10' had no markings at all. I looked over half a dozen of each real carefully, no stamps of any kind. I even bought a couple of the no-stamp 2x6's, real nice stuff with straight grain, only a few small knots. It probably would have been select structural if it were graded.
But what are they thinking? Doesn't anybody pay attention to grades any more? Don't inspectors want to see a few stamps here and there? Or does HD figure their customer base is 100% bootleg jobs? Is it so very much cheaper without grading?
