Lodgepole Pine is the primary species of wood we choose to stock for our agricultural poles. The Lodgepole Pine tree is known for its long, slender trunk and high, thin crown. It is popular in vineyard and fence applications due to its ability to flex with heavy loads without breaking.
Lodgepole Pine logs are run through a machine that peels off the bark and cambium layer of the pole. This leaves the sapwood layer, which retains the chemicals during the treatment process.
Since alot of our poles are put into agricultural applications, we treat most of our stock with CCA (Chromated Copper Arsenate
) to a .40 pcf (per cubic foot) retention for ground contact use. For residential applications, ACQ (Alkaline Copper Quaternary
) is the recommended treatment because it provides the same
level of performance as CCA pressure treated wood without the use of arsenic and chromium.
We frequently fill special orders where we treat our Lodgepole Pine poles with Penta (Pentachlorophenol
). The cost is higher than that of CCA, but we see these going into farms and ranches for fencing applications. We often hear ranchers say their horses will not chew on it. This is very likely a reaction to the P9 oil solvent used during the treating process of Penta.
