Compared to traditional materials, fiber reinforced polymer (FRP) composites are more durable, require less maintenance, and provide a longer service life. Lower Total System and Lifecycle Cost GridCore Composite Poles have an expected service life of up to 80 years, compared to 30-40 years for wood poles. The values for 14 x 0.75 in pole have been verified by third-party full-scale testing.
