Pultruded Glass Polyester and Glass Vinylester profiles are readily available in a wide range of configurations—from standard shapes like angles and channels to hat channels and more complex custom profiles.
NEMA GPO-3 pultrusions are widely used across multiple market segments, including OEM transformers, switchgear, and high-voltage electrical service and maintenance applications.
GPO-3 is both flame retardant and track resistant, rated for UL Temperature Class B (130°C). It delivers low thermal conductivity and minimal thermal expansion, making it suitable for all but the most demanding electrical environments.
Glass Vinylester pultrusions are available in the same popular profiles—and many additional configurations—offering superior moisture, chemical, corrosion, and UV resistance. These characteristics make them an excellent choice for use in harsh or specialized applications across a variety of industries.
