also, how come older poles are brownish and more porus whereas newer poles are a light tanish color and smoother? i've noticed some poles here go up the light tan color and other poles part of the same pole renewal project will be a darker even smoother color and look treated. my street is liek that. all the poles are a light tan color and one is a nice dark color and looks "newer" than all the others.
Most of PEPCO poles seem to have been treated with something, not sure but it seems they have some kind of tar or gloss on them. and the poles tend to be much darker.....
Good example here both sides were actually new poles, and the right side is PEPCO note how its darker while the left side are BGE and the poles are lighter....
IIRC, the dark brown poles are probably treated with creosote and the greenish ones are treated with copper based CCA, ACQ, copper azole type preservatives.
Most of the preserved wood you find at HD or Lowe's is usually ACQ or copper azole.
