Compared to traditional pole 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. Customized and Consistent Material Manufactured in a continuous pultrusion process, GridCore poles are engineered for consistent strength and uniform appearance and are not subject to warping, shrinkage, or splintering.
