The new pressure treated lumber is preserved with Alkaline Copper Quaternary (ACQ), or also known as Copper Azole (CBA). Both of these chemical treatments are to have less environmental and health risks, but they’re also more corrosive to nails, screws, and any other metal fasteners that come in contact with lumber.

ACQ-treated lumber is pressure-treated with alkaline copper quartenary , a copper-based chemical forced into the wood to preserve it against decay and insects. This preservative replaces the arsenic-based chemical preservative that was used for many years but was deemed too poisonous for use around children. Preserve ACQ - Alkaline Copper Quaternary (ACQ) is a water-based wood preservative formulation made of soluble copper and a quaternary compound.

The soluble copper makes the wood very resistant to biological attack, and a quaternary ammonium compound (quat) acts as biocide and insecticide, increasing the tolerance of the treated lumber to copper-resistant bacteria and fungi. It’s typically used for decks, mailbox posts, light posts, playgrounds, utility polls, picnic tables, home building foundations, and much more. Pressure-treating wood saturates wood under pressure with a chemical preservative. Dust can form an explosive mixture in air.

The wood is placed in a depressurized holding tank that removes the air and replaces it with a preservative. This process is the best way to avoid harmful rot and insects but does not prevent weathering and corrosion. Pressure - Treated Pine meets the highest grading standards for Pressure - Treated Pine meets the highest grading standards for strength and appearance. This double treated Ground Contact lumber must be used for applications where treated lumber is difficult to maintain, repair or replace.

Since it contains high levels of copper, ACQ - treated lumber is five times more corrosive to common steel, according to American Wood Preservers Association (AWPA) test. Composite plastic lumber. It is necessary to use double-galvanized or SS fasteners in ACQ lumber because of its highly corrosive effect.

The result is ACQ (Alkaline Copper Quaternary) treated lumber. The new ACQ treated lumber contains a very high level of copper to replace the arsenic. These compounds are much less toxic and have shown to not leach into soils the way CCA and Creosote have.

This does not eliminate health risks but significantly minimizes them. Pressure - treated lumber is wood that is engineered for use on projects that are exposed to the elements. Surfaces of oil-based treated wood may not be paintable and odors may be stronger. Manufacturing methods for treating wood include pressure treatment, dipping, or soaking.
