Main Functions: 1) Vehicle Traffic Control: The square stainless steel bollards can establish a round-the-clock vehicle management and control, preventing unauthorized vehicles from entering forcibly, thus maintaining the order and safety of the square. 2) Boundary Definition and Warning: By setting up bollards, the boundaries of the square can be clearly delineated, serving as a warning at the same time, reminding passing vehicles to give way, and preventing collisions with pedestrians or facilities within the square due to misoperation or overspeeding. 3) Effective Collision Interception: The stainless steel bollards possess high impact resistance, effectively blocking the impact of vehicles in case of collisions, intercepting abnormal vehicles outside the safe area, and protecting the safety of personnel and facilities within the square.
