Pressure Treated Lumber

Contact Us Today
Treated lumber is a proven building material. It is impressively strong, cost-effective, renewable in large quantities (we are currently making more southern yellow pine than we use), and visually appealing. Lumber’s foremost drawback is its susceptibility to attack by insects and other natural enemies but modern treatments have made this concern nearly irrelevant.

Pressure Treated Southern Yellow Pine

Southern yellow pine is the most commonly used wood in the United States. In addition to being the strongest softwood structural pine, it is especially “treatable”, abundantly grown, and dimensionally stable. The combination of these characteristics makes pressure treated southern yellow pine an excellent choice for numerous construction projects from both the design and economic points of view.

Treatment Options (Chemicals Used to Treat Lumber)

Although there are numerous treatment options available most modern construction projects call for one of the following three waterborne pressure treatment chemicals:

  • CCA (Chromated Copper Arsenate) used mostly in commercial, industrial, & marine projects
  • MCA (Micronized Copper Azole) used mostly for consumer & commercial projects
  • CA (Copper Azole) used mostly for consumer & commercial projects
Each of the options is effective for protecting wood against wood boring insects, fungus, and bacteria. CCA is considered by many to be the strongest treatment option but is only available for use in commercial structures.

CCA Pressure Treated Lumber
CCA is considered by many professionals to be the best lumber treatment. It is clean to work with, long-lasting, and relatively non-corrosive to metal hardware and fasteners. In fact, the largest problem with CCA is effectively one of perception because it contains arsenate, a naturally occurring form of arsenic. After extensive research by the EPA, no proven instances of harm from CCA treated wood have ever been recorded but, as a matter of precaution, CCA treated lumber is no longer permitted for residential applications such as privacy fences or decks. CCA treated wood is permitted and safe for industrial, marine projects.

MCA Pressure Treated Lumber
MCA is an effective lumber treatment option approved for consumer applications. It is now commonly used for projects ranging from decks to docks to piers. In addition to being nearly colorless and odorless, MCA is not considered corrosive to fasteners and is a good treatment option overall.

CA Pressure Treated Lumber
CA treated lumber (also known as CA-B) was standardized by the AWPA in 2002 and is an effective treatment for residential, commercial and marine applications. CA treated wood has a slight greenish-brown tint and little or no odor. It is not considered corrosive to hardware and fasteners.

The Pressure Treating Process
This ultra-brief explanation of the lumber treating process gives a basic understanding of the process of how your lumber is treated:

  • Wood (in large quantities) is put into a large sealed treating cylinder
  • Fluid containing the wood preservatives is pumped into the cylinder
  • Pressure is applied to the cylinder to force the chemicals into the wood fibers
Can You Partially Pressure Treat Lumber? No. This is a common question but now that you have a little understanding of the pressure treating process, you can see that lumber is either pressure treated or not. It is an all or none process. You can, of course, vary the level of treatment (retention level) applied to the wood depending upon the application for which the wood is destined.
