| Fixed Steel Bollard | Permanent vehicle separation and access control | 750–1,200 mm | Galvanized or stainless steel | High resistance when correctly anchored; performance depends on design and foundation | Core-drilled or surface-mounted with concrete anchors | Building fronts, loading areas, pedestrian zones, and protected entrances | Reflective bands, contrasting finishes, or integrated lighting | Low; inspect anchors, corrosion protection, and visible damage |
| Removable Bollard | Temporary or scheduled vehicle restriction | 750–1,000 mm | Steel, stainless steel, or aluminum | Varies from decorative control to heavy-duty protection | Sleeve or receiver set into the pavement; bollard can be lifted out | Service access points, event areas, private roads, and emergency routes | Reflective tape, high-contrast paint, or reflective panels | Moderate; clean the receiver and check locking hardware |
| Retractable Bollard | Flexible access control without removing the unit | 600–900 mm above ground when raised | Steel or stainless steel | Usually intended for controlled access; impact rating differs by model | In-ground sleeve with manual, gas-assisted, or mechanical operation | Driveways, parking entrances, pedestrian streets, and restricted lanes | Reflective bands and high-visibility top sections | Moderate; remove debris and check drainage and moving parts |
| Flexible Polyurethane Bollard | Lane guidance and visual channelization | 450–1,000 mm | Polyurethane or other resilient polymer | Bends or deflects during low-speed contact and usually returns upright | Bolted base or surface-mounted plate | Parking lots, work zones, traffic islands, and lane separators | Bright colors and wide reflective collars | Low; replace units that are split, heavily abraded, or no longer rebound |
| Telescopic Bollard | Compact, manually controlled vehicle restriction | 600–900 mm when extended | Steel or stainless steel | Provides physical resistance; actual protection depends on construction and anchoring | Sleeve installed below or flush with the pavement | Residential drives, commercial entrances, and areas with limited space | Reflective strips or contrasting powder coating | Moderate; lubricate or service the locking mechanism as specified |
| Automatic Rising Bollard | Controlled vehicle access with remote or automated operation | 500–900 mm when raised | Steel or stainless steel with powered drive components | Security performance ranges from traffic management to certified impact resistance | Engineered in-ground foundation with power, controls, and drainage | High-security entrances, restricted streets, civic sites, and managed car parks | Reflective bands, warning lights, audible alerts, or illuminated collars | High; requires scheduled inspection of controls, drainage, seals, and power systems |
