UTILITY POLES - Douglas fir

 

Grown primarily in the northwest section of the United States...

Douglas fir has been a choice for investor owned utility companies and electric cooperatives for decades. Coastal Douglas fir is remarkably knot free, strong and light. It is considered to be one of the best known softwood timbers. Readily available in transmission and distribution sizes in lengths from 20 - 130 feet, sapwood is easily treated. With a long history of safe and dependable use, this material has been approved by ANSI, CSA and REA.

 

While a complete line of Douglas Fir transmission and distribution poles are in stock and available at our West Coast manufacturing facility, transmission poles are also in inventory at our east coast locations.
