Galvanized steel, high-quality paint, corrosion-resistant, oxidation-resistant, and rust-resistant. The car barrier's locking arm features reflective strips, ensuring excellent visibility in low light or at night. Law enforcement can use it for traffic control or as an emergency roadblock. Steel pipe bollards can protect buildings, pedestrians and equipment from collisions with vehicles or forklifts. If the parking barrier is blocking the road, you can use a key to separate the barrier from the base. The surface layer is designed with a strong reflective film, so it is not easy to fade or peel off even when exposed to the outside for a long time.
