The density of ACQ (Alkaline Copper Quaternary) pressure-treated wood typically ranges from 30 to 55 pounds per cubic foot, depending on the type of wood used and its moisture content. ACQ treatment adds weight to the wood due to the preservatives, which can slightly increase its density compared to untreated wood. It's important to note that density can vary based on species and treatment levels. Always consult specific product data for precise measurements.
Manufacturers have screws and nails ACQ approved marked on the packaging.
When using pressure treated wood you should look for a screw specifically rated for use in ACQ (pressure treated) lumber or use stainless steel.The greed coating may be an ACQ coating but you would have to check the package.You should NOT use zinc deck screws as the copper content in ACQ lumber will react with it causing the screws to corrode.
The best pressure treated wood for ground contact is typically either ACQ (Alkaline Copper Quaternary) or CA (Copper Azole) treated lumber. These types of treated wood are specifically designed to resist decay and insect damage when in direct contact with the ground.
The different types of pressure treated wood available in the market include chromated copper arsenate (CCA), alkaline copper quaternary (ACQ), copper azole (CA), and creosote.
The different types of pressure-treated wood available for outdoor projects include chromated copper arsenate (CCA), alkaline copper quaternary (ACQ), copper azole (CA), and micronized copper azole (MCA).
ACQ treated lumber is beneficial for outdoor construction projects because it is resistant to decay and insect damage, which helps extend the lifespan of the structure. Additionally, ACQ treated lumber is environmentally friendly and safe for use around plants and animals.
Yes, it is generally safe to use pressure-treated wood for raised vegetable garden beds, especially if the wood is treated with modern, safer preservatives like alkaline copper quat (ACQ) or copper azole, which are less toxic than older treatments. However, some gardeners prefer to use untreated wood or line the beds with a barrier, such as landscaping fabric, to prevent any potential leaching of chemicals into the soil. Ultimately, it's important to consider the type of treatment and your personal comfort level regarding chemical exposure.

The majority of wood products are treated with water-borne preservatives, the most common being chromated copper arsenate (CCA), ammoniacal copper quat (ACQ), and ammoniacal copper zinc arsenate (ACZA).
Pressure treated lumber is beneficial for outdoor construction projects because it is resistant to rot, decay, and insect damage, making it more durable and longer-lasting than untreated wood. This type of lumber is also able to withstand harsh weather conditions, such as rain and snow, which helps to maintain the structural integrity of the project over time. Additionally, pressure treated lumber is cost-effective and widely available, making it a practical choice for outdoor construction projects.
Acq's population is 502.
Lumber used to be pressure treated with arsenic - a lethal poison - specifically chromated copper arsenate - which turned the lumber slightly green- but legislation was passed several years ago ( 2003 ) stopping the use of arscenic and going to less toxic substances. Another copper solution called ACQ is used. The copper makes the wood more rot resistant and is toxic to some insect life. Termites would tend to favor untreated wood. While the bottom sill of balloon frame structures may be pressure treated, the framing above the bottom sill is most often not treated. It is too expensive to build structures entirely from pressure treated lumber. The best defense against termites is to keep the wooden parts of the structure well off the soil with stone or concrete foundations and keep those foundation lines clear of flower beds mulched in wood chips so as not to give termite colonies easy access.
