What Is A Bollard?

A bollard is a short vertical post. Early bollards were for mooring large ships at dock, and they are still in use today. A typical marine bollard is produced in cast iron or steel and shaped somewhat like a mushroom; the enlarged top is designed to prevent mooring ropes from slipping off.

Today, the word bollard also describes a variety of structures used on streets, around buildings, and in landscaping. 

Bollards generally fall into three types of applications:

  1. Decorative Bollards – decorative bollards for architectural and/or landscaping highlights;
  2. Traffic and Safety Bollards – bollards that provide asset and pedestrian safety, as well as traffic direction; and
  3. Security Bollards and Post Covers – decorative, impact-resistant bollard enhancements

Decorative Bollards

Decorative bollards www.ligman.com/th/easy-garden-design-with-bollards are manufactured to harmonize with both traditional and contemporary architectural styles. The latter lean toward visual simplicity – often straight-sided posts with one or more reveal near the top. Styles made to match various historic periods usually have more elaborate shapes and surface details. 

Traffic and Safety Bollards

The most common bollard applications are traffic direction and control, along with safety and security. The first function is achieved by the visual presence of the bollards, and to some extent by impact resistance, although, in these applications, visual deterrence is the primary function. Safety and security applications depend on higher levels of impact resistance. 

Security Bollards and Post Covers

The aftermaths of the 1995 Oklahoma City bombing and September 11, 2001, attacks saw a sharp rise in the installation of bollards for security purposes. Anti-ram installations include not only posts but other objects designed to resist impact without presenting the appearance of a protective barrier, such as large planters or benches that conceal bollards.
