The barricade posts are made of premium PU particles, which perform well in thermal insulation, waterproof, and shockproof. They have a reflective band design that can reflect light efficiently, even at night, to be noticeable enough to warn passengers. The parking delineators have integrated bodies and bases, and three holes are pre-drilled in the base for easy installation with expansion bolts. They can be used in combinations and have a wide application in expressways, parks, neighborhoods, intersections, parking spots, and streets.
