Superior Wood Treating Products

Arrow Lumber & Hardware proudly stocks Superior Wood Treating
at all 6 of our locations.

We carry lumber that has been treated with ACQ, an Alkaline Copper Quat, that is copper based for long term protection from rot, decay, and insect attack, without the presence of hazardous chemicals. This is an environmentally friendly treatment.

ACQ Treated Lumber can be used in above ground, below ground and fresh water immersion applications. This allows the product to be used in residential, commercial, and industrial projects. Three levels of ACQ Treatment are produced:

  • 0.25 for above ground use

  • 0.40 for ground contact, fresh water applications

  • 0.60 for permanent wood foundations, as well as poles for barn applications.
