Carsonite Composites invented the first flexible highway delineator, and we continue to stay at the forefront in permanent, flexible, impact resistant roadside products. Our advanced composite delineators are unlike any other, with a formula of special polymers designed specifically to flex above ground while maintaining their durability - even in temperature extremes. Proven to withstand repeated vehicle impacts, Carsonite composite delineators remain the industry standard. We offer a wide variety of both drivable flexible and surface-mounted delineators.
