Well, I was at Lowe's today pricing items for a bid that I am doing and
walking past the stacks of PT lumber I saw, "Born On" dates, on 8"x10"
tables stapled on the banded bundles.
Does this mean wait a year from that date to buy the wood after it is
Does it mean that they have the freshest PT lumber? Do you really want
fresh PT lumber.
Does anyone have a clue?
If I were forced to take a guess, I'd guess that it has something to do with
the change in formulation of the brew that occurred at the first of the year.
The old brew couldn't be used after the first of the year and the new brew is
much more corrosive to steel fasteners and hardware than was the old. So, with a
"born-on" date, you know whether you have the new brew or part of the dregs from
the old brew. That tells you whether you need the extra corrosion proofed,
triple zinc coated hardware or whether you can use the older hardware.
Of course, you can tell the same thing from the tags/stamps on the boards, so
maybe it is just to let you know you aren't getting stale boards.

I'd guess the first response to be correct. Building inspectors are paying
close attention to the hardware you use when building with the new PT
lately. Best bet is to use stainless steel or the new galvanized labeled
for use with next generation PT. Also, I'd recommend keeping the little tags
on the end of the lumber to show the inspector if he asks. -dave
