A significant amount of our business is the distribution of planting and tree stakes to farm, landscape, and nursery supply stores. We sell for resale only and as such do not sell directly to the farmers, landscape contractors, or nurseries.
All of our stock is treated with ACQ (Alkaline Copper Quaternary
). It is the recommended treatment because it provides the same level of performance as CCA pressure treated wood without the use of arsenic and chromium. Treated wood stakes often do not have enough sap wood to allow for a full treatment, as it is the sap wood that absorbs the preservative.
Due to a high percentage of impenetrable heartwood, wood stakes are "Treated to Refusal". This phrase "Treated to Refusal" indicates that the wood is treated under specified conditions until it refuses additional preservative, a point "usually" below the requirements of industry standards.
