Unbranded 6 x 6 x 18' #1 Critical Structural CCA .60 Green Pressure Treated Timber

Chromated Copper Arsenate (CCA) pressure treated wood products have stood the test of time. CCA pressure treated wood that was installed as far back as the 1940s still remains in serviceable condition today. Though restricted from use in residential applications, it's still widely accepted in the building industry as the material of choice for post frame buildings. The CCA wood preservative system meets the American Wood Protection Association (AWPA) Standards and meets all major building code requirements.
