Atlantic Fence uses ACQ (alkaline copper quaternary) pressure treated southern yellow pine. ACQ is an environmentally safe formula that is arsenic free and provides long term protection from dry rot, decay and insect damage. ACQ-treated wood is safe for use in the garden, for picnic tables, and in areas used by animals, fish, and children.
Pressure-treatments will vary depending on intended use: Ground contact wood is more heavily treated to resist water damage from wet soil. Properly used, pressure-treated wood will stay strong and useful for decades.
