Bollards are short, sturdy posts used to control vehicle access and protect pedestrians in various environments. They can be made from materials like metal, concrete, or plastic and are often found in urban areas, parks, and parking lots. Bollards help define spaces, guide traffic, and prevent vehicles from entering restricted zones. In addition to their functional role, bollards can also enhance the aesthetic appeal of a location. Some are designed with artistic elements or bright colors to blend with the surroundings. They are commonly used in conjunction with other safety measures, such as traffic signs and barriers, to improve overall safety.
