TREATMENT TYPES

CCA_1

DuraPine® CCA treatment is a solution of chromated copper arsenate. The preservative has been formulated to protect poles 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

Lower Maintenance - 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.

Low Conductivity & Low Corrosivity - 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.

A Co-op Favorite - Rural Utilities Service approved.

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

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

Vertically Integrated - 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.
