The History of the word Bollards
The bollards are also known as lifting column, lifting road barrier, anti-crash bollards, hydraulic lifting bollards, isolation barrier and so on. The term Bollard originally described a short, vertical column that was often used when large vessels in the port were moored. Now its meaning has been expanded to describe various facilities for managing pedestrian traffic, protecting critical infrastructure, setting perimeters, and distinguishing roads ranges.
According to legend, the street guardrail began in the 17th century and is shaped like an inverted cannon, used as a boundary setting and a city sign. Since then, they have appeared more and more in our daily lives, such as supermarkets, restaurants, hotels, shops, and stadiums. We can often see bollards in different shapes, either to indicate the direction of travel, or to protect us from injury, or to tell if parking is possible here. These beautifully shaped pillars landscaping the environment, distinguishing between sidewalks and roadways, and sometimes as chairs allow us to sit down and enjoy lunch.
Fixed metal bollards are the most commonly used one. They are generally painted pillars with a height of about 36cm, which are internally filled with cement and installed on the ground. Some bollards are square, but most are cylindrical, angled or flat bristle. The size, color, texture, shape, and function of the bollards are numerous. They are either fixed, moveable, or telescopic, and can also be used as an ornament to decorate the original steel bollard.
Many bollards have aesthetic features, especially metal bollards, which are used to prevent damage to pedestrians and buildings. They are the easiest way to control access and also serve as a fence to define specific areas. They can be fixed to the ground individually, or they can be lined up to close the road, so that the vehicle is not allowed to enter, thus ensuring safety. The metal fixed bollards to the ground serve as long-term fences, while the retractable and movable bollards to ensure the entry of certified vehicles.
There are three main applications for the bollards—building (decoration), safety (impact resistance) and landscaping (outstanding perimeter). All bollards can be used in architecture and landscaping, differing only in style, shape, and material. When it comes to safety applications, different bollards are used to block different objects. For example, the bollards used to stop traffic are different from the bollards used to deal with protection (impact) problems. When it comes to safety applications, first consider the size of the vehicle and the speed of the vehicle when it hits.
