[Subject Prev][Subject Next][Thread Prev][Thread Next]
I have found "Selection and Use of Pressure-Treated Wood" published by
the Forest Products Society as their Publication No. 7299 to be a good
reference on the subject. They can be reached at 608-231-1361. I think
it costs about $15.  Worth the bucks.
