What does ACQ pressure treated pine mean?
Let us give you a quick chemistry class. Pressure treated southern yellow pine is what every one refers to as just plain pressure treated lumber. It is grown mostly in the southeastern United States and is pressure treated to help eliminate termite infestation, rot and decay and comes with a lifetime manufactures warranty against rot and termite infestation. The chemicals they use to treat the lumber are Alkaline Copper Quat, hence the name ACQ. These are the new preservatives that are used since the government banned the use of CCA in 2003. CCA stands for Chromated Copper Arsenate. The new pressure treated lumber is suppose to be better for the environment and humans but it sure doesn’t sound like it, does it?
