Because of the flip on the century, there was a need for specifications to create a consistent offer of Wooden utility poles with predictable structural capabilities. In 1908, standards for spherical timbers had been designed and soon after, the American Nationwide Benchmarks Institute, or ANSI, adopted standards specifically for wood utility poles, defining the dimensions and features authorized.

Even in the technology dominated twenty first century, wood poles keep on being the highest choice for utilities.
