ACQ pressure treated lumber is ideal for decks, fencing, and all kinds of outdoor building needs. ACQ was developed to provide long term protection against rot, decay and termite damage in above ground, ground contact, and fresh water applications. Unlike ordinary pressure treated wood (CCA), ACQ contains no arsenic, chromium, or other EPA-listed hazardous chemicals. ACQ was developed in response to a growing concern about the chemicals used in pressure treated lumber and their impact on the environment.
ACQ is a strong, durable wood which weathers to a warm, brown color, not gray like other pressure treated wood. It has a beautiful finish that can be painted, stained or left to weather naturally. It is both lighter and stronger than plastic alternatives. Treated with ACQ®, an environmentally advanced copper and quat preservative system that is arsenic- and chromium-free. Provides long-term protection from rot, decay, and termites without the use of any EPA-listed hazardous chemicals.
