Bollard sizes, colors, textures, shapes, and functions are vast. They can be fixed, movable, telescopic, or even serve as decorative elements to adorn existing steel pipe guard posts. Many bollards possess aesthetic qualities, especially metal ones, which are used to prevent vehicle damage to pedestrians and buildings. They can be the simplest method for controlling entry and exit, and also act as barriers to define specific areas. They can be individually mounted on the ground or arranged in a line to block roadways, preventing vehicles from entering, thus ensuring safety. Fixed metal bollards serve as long-term fences, while telescopic and movable bollards ensure authorized personnel and vehicles can enter.
