Metro Bollard Options: Flexible Bollards or Fixed?

Few inventions have received less attention, yet done more good, than the metro bollard.  This simple device helps to channelize traffic, establish boundaries, and shield citizens from sources of danger.

One of the choices public planners need to make involves what type of bollards to install in a given location.  Here are some guidelines for choosing between fixed and flexible bollards.  These are general rules that can be applied to virtually any area.

Benefits of Fixed Bollards

  • Resistance to forceful intrusion – In areas where deliberate attempts to cause harm are likely, solid bollards are by far the best choice.
  • Durability – Fixed bollards are weather-resistant, durable, and sturdy, even in the face of severe conditions or outright abuse.  This makes them preferable in areas with high crime rates or extreme weather conditions.
  • Deterrent effect – Solid bollards are usually made of steel, concrete, stone, or other strong materials.  They have a potent psychological effect on those who might otherwise engage in risky or unlawful behavior.

Benefits of Flexible Bollards

  • Portability – Flexible bollards are generally lightweight and easily transportable, making them ideal for short-term use.  One example is school crossings, where guards may only need to use bollards for an hour or two a day.
  • Safety – Flexible bollards are designed to “bend rather than break.”  This makes them preferable to fixed bollards when public protection, including the safety of the person entering a prohibited space, is all-important.
  • Affordability – In most cases, flexible bollards cost less than fixed bollards.  In these budget-strapped times, this is a powerful selling point. 


Both fixed and flexible bollards serve vital roles in helping to ensure public safety.  The strengths and drawbacks of these different types of metro bollard, however, make each of them best suited for specific situations rather than all-purpose use.  Deciding which type of metro bollard is best for a given scenario comes down to good judgment and knowledge of both products.
