ACQ Treatment

ACQ-treated pine is an eco-friendly choice, providing peace of mind with every use. Plus, all our ACQ products come with a 50-year treatment warranty.

ACQ (Alkaline Copper Quaternary) treated timber is an arsenic- and chrome-free alternative to CCA-treated timber, developed to provide long-term protection for wood exposed to exterior applications.

ACQ is an eco-friendly alternative to timbers containing chromium or arsenic. When you use ACQ-treated timber for your project, it will have minimal chemical leaching into the surrounding environment. This makes ACQ-treated pine a great choice, offering similar advantages to hardwoods and bringing pine back into mainstream construction.

APPEARANCE

ACQ-treated timber weathers to a honey brown color before fading to a driftwood grey after exposure to the elements.

SUITABILITY

Outdoor use, including posts and poles, roundwood for decorative use, landscaping, fencing, foundations, telephone poles, motorway barriers, decking, trellis, and house construction.

ACQ-treated pine is also a popular choice for government projects, playgrounds, parks, and gardens.

PAINTING & STAINING

ACQ-treated timber can be painted or stained to match most outdoor color schemes. Always follow the paint manufacturer’s recommendations.

WARRANTY

ACQ H3.2-treated pine comes with a 50-year treatment warranty.
