The North American Wood Pole Council is an independent council representing the producers and suppliers of wood poles and crossarms in North America. A primary focus of the council is to support and sustain the use of the products and to provide information to the designers, specifiers and users of the products.


Advantages of penta-treated poles highlighted

Penta statement

Penta-treated wood poles remain the backbone of the overhead utility system in this country. A new statement attests to the safety and effectiveness of penta used in preserving utility poles and refutes recent concerns raised about the preservative.

The statement details the 80-plus years of service performance for penta-treated poles and notes the preservative has been extensively reviewed by the U.S. EPA and others.

Over the decades of use, there have been no documented incidents of harm or illness to any individual caused by casual contact with penta-treated utility poles.

Bulletin details utility pole performance in wildfires

Tech Bulletin WUI

NAWPC has published a new Technical Bulletin reviewing research on the performance of wood and steel utility poles in wildland fire hazard areas.

The 12-page report details the temperatures and stresses utility poles can face during wildfires. Citing recent reseach, the report offers data on how wood poles and steel poles are affected by such conditions, noting while wood chars and provides some insulation against the effects of fire, steel begins to lose strength at 392 degrees F.
