ACQ Treatment

ACQ (Alkaline Copper Quaternary) treated timber is an arsenic and chrome free alternative to using CCA treated timber that has been developed to provide long term protection to wood exposed in exterior applications.

ACQ is an eco-friendly alternative to other timber containing chromium or arsenic. When you use ACQ treated timber for your project, there will be minimal leaching of chemicals out of the timber into the environment around you. This creates a pine timber that has similar advantages to hardwoods, bringing pine back into mainstream construction.
