One tough PUPI.

Built Tough // Pultrusion Process

PUPI® has more fiberglass pultrusion experience than any crossarm manufacturer.

PUPI® has more fiberglass crossarm pultrusion experience than any manufacturer. Pultrusion is a highly automated and controlled process for manufacturing continuous fiber reinforced composite materials of the highest strength and reliability. Continuous glass fibers are combined with fiber mats, impregnated with thermosetting resin and drawn through heated dies to cure the structure. For PUPI® products, an ultraviolet inhibitor is included in the resin, a resin-rich veil mat forms the surface of the part and SunGUARD® UV resistant coating is thermally bonded to produce composite products with unmatched resistance to outdoor weathering. PUPI® pultruded products are designed and manufactured under careful process control to give uniform, predictable properties and reliable performance.
