Concrete Bollards – Our 6″ diameter concrete bollards feature a 1″ reveal and come in a 72″ standard length (customizable). These attractive bollards provide an aesthetically pleasing delineation to guide the flow of pedestrian traffic. Please keep in mind that because of their small diameter the BOC6R’s will not withstand repeated bumps or hits from vehicles. If they are struck by a car, they will need to be replaced. If they are being installed in parking lots or high traffic areas we recommend steel bollards or larger diameter concrete bollards be used instead.
