CCA Treated Wood

CCA Treated Wood is treated at our Coos Bay, Oregon, Loveland, Colorado, and Washougal, Washington manufacturing plants. Wood species treated include Hemlock fir, Lodgepole Pine, and Ponderosa Pine.

CCA stands for Chromated copper arsenate. CCA is a chemical wood preservative containing chromium, copper, and arsenic. CCA is used in pressure treated wood to protect it from rotting due to insects and microbial agents. The Environmental Protection Agency (EPA) has classified CCA as a restricted use product and it is not specified for residential uses. It may however be used for industrial and agricultural applications.
