How do bollard work?

The working principle of bollards is to act as physical barriers to control or restrict vehicle access by blocking, guiding, or restricting entry to specific areas. Depending on the type, bollards can be fixed, movable, or automated, and their uses are diverse, ranging from security to traffic control and property protection.

 

General Function

 

Blocking Vehicles:

Solid or reinforced bollards can prevent vehicles from entering protected areas.

Some bollards have been tested for collision resistance and can withstand high-speed vehicle impacts.

Controlling Access:

Removable, retractable, or automatically adjustable bollards can be raised or lowered as needed to allow authorized access.

Guiding Traffic or Pedestrians:

Arranged in rows to guide vehicles or pedestrian flow, especially in busy public areas.

Marking Boundaries:

Visually separating sidewalks, bike lanes, or storefronts from roadways.

 

How bollards provide protection?

 

Safety bollards are made of steel or reinforced concrete and are sometimes rated to stop vehicles traveling at speeds of 30-50 mph.

Shallow installation or deep foundation designs provide strength and prevent forced entry.

Locking systems on retractable/removable bollards prevent tampering or unauthorized use.
