ACQ (Alkaline Copper Quaternary) treated lumber is pressure-treated for exterior/outdoor use, resisting rot, decay, and insect damage in decks, fences, and ground-contact projects. Suitable for flower beds, retaining wall perimeters, fencing, deck framing and much more.
PLEASE NOTE: Not suitable for vegetable garden beds as the ACQ treatment will poison your vegetables. Please consider using cedar lumber for garden bed perimeters.
