Rochling Glastic composites pultruded channels and angles are similar in material construction to the Grade UTR flame and track resistant laminates. A small amount of continuous glass roving is added to aid in pultrusion processing. These high-strength pultruded shapes have a wide variety of uses in both electrical and non-electrical applications. They are arc and track resistant and have a UL94 rating of V0. These versatile GPO-3 shapes are easily machined to fit a variety of needs in electrical design and construction. They are readily available in a variety of profile sizes and lengths. - Rochling Glastic structural composite materials are available in numerous channel and angle configurations. We are the only manufacturer with a full line of pultruded angles and channels that all meet or exceed NEMA GPO-3 specifications. In addition to outstanding electrical properties, these structural composite angles and channels have a high strength-to-weight ratio, and are UL Recognized and flame, arc and track resistant.
