A bollard is a small post used installed & arranged to create a protective or architectural perimeter. When installed primarily as a visual guide, bollards guide traffic and mark boundaries. They come in a wide range of shapes and styles to accentuate  or visually stand out in their settings. Bollards can also be made to physically block vehicle incursion, protecting pedestrians and property. These security bollards may have decorative elements, or be chosen to complement the landscape, but their main purpose is resistance to collisions & impacts. Bollards can be made from almost any material, depending on their needed function, but the most common bollards are metal, stone, cement, or plastic.
