DuraPine® CCA treatment is a solution of chromated copper arsenate. The preservative has been formulated to protect poles and crossarms from becoming a food substance for termites and fungi while keeping the wood clean, odorless, non-staining, and safe to handle when used as recommended.


Key Features

DuraPine CCA is a fixed preservative which means there is very little migration of chemical. This often reduces the need for future groundline remedial treatment.

Our CCA treatment is an oxide, so no salt by-products can impact pole conductivity and corrosivity. The low conductivity of dry CCA poles provides linemen additional protection from potential current leakage.


Rural Utilities Service approved.


The need to rotate poles during storage is eliminated due to the preservatives fixed position. 

DuraPine CCA treated poles are backed by a 50-year warranty against damage from termites and fungal decay.

For over 25 years, Koppers Carbon Materials & Chemicals business has been a quality manufacturer of CCA, ensuring a steady supply to meet future treatment needs.
