Quality Standards and Specifications
The BROOKS team is proud of the quality of the products we manufacture.
Millions of our distribution crossarms and transmission framing
components have been installed on utility poles in the United States
and other parts of the world. Many of these have been in service for
over 60 years. Our years of success are the result of following
stringent specifications in purchasing, grading, production, treating,
and shipping. This attention to detail is your assurance that the
finished product will fully meet your specified standards.
BROOKS Douglas fir Crossarms and Transmission Framing meet the latest revisions of the applicable product quality standards and specifications shown below. Most of these reference additional standards for method and quality.
