Bollards are the short metal posts initially used for shipping wharves, but now used in parking lots, traffic control situations and trucking bays. They are designed to be fixed around architecture or populated sites that wish to keep traffic out. Spaced correctly they allow people free access whilst preventing entry by most all driven vehicles. Alternately, they may be deployed to keep trucks and other vehicles with a certain enclosed space, protecting the entrances to buildings.
Bollards can be made from any heavy duty material. Stainless steel bollards are very long lasting and are well suited to stylish public areas such as malls, beach fronts or open shopping areas. Steel bollards are also durable and can be painted with safety colour if appropriate.
