High visibility

Yellow steel bollards

The high-visibility workhorse. Steel pipe finished in safety yellow with reflective banding, used wherever a bollard needs to be seen before it is hit. This is the highest-volume bollard on most warehouse and industrial sites, and the one that gets replaced most often.

A round yellow bollard with a red reflective band and a square yellow bollard with black hazard striping, bolted to a paved walkway outside a commercial building

Where it is used

  • Loading dock corners, door tracks and dock aprons
  • Forklift aisles and pedestrian walkway edges
  • Racking ends and equipment protection inside the building
  • Gas meters, electrical panels and fire risers
  • Parking garage ramps and pillar corners
  • Driveways, parking lots and industrial yards

Not sure which option fits?

Send a photo of the location and tell us what you are protecting. We will specify it and quote it within 24 hours, including the cheaper option if that is the right one.

Before you order

Choosing the right option

Which height should I order?

36 inches for inside the building: aisle ends, racking, equipment, where the driver is seated on a forklift. 42 inches outdoors at store fronts, ramps and walkways, which is the common commercial standard. 48 inches where trucks rather than cars are the risk. If you are unsure, send a photo of the location and we will specify it.

Round or square?

Round for open positions and anywhere the bollard is seen from all sides. Square where the post sits against a wall, a column or a racking upright, because the flat face closes the gap a round shaft leaves. Both take the same anchors.

What do I need for the base?

All four mount on an 8 inch base plate with 5/8 inch holes, anchored to concrete. The concrete needs to be sound and thick enough to hold the anchors. Asphalt and pavers usually need a different approach. Send a photo of the surface if you are not sure.

Will it stop a truck?

Be careful with this question. These are protective and deterrent bollards for the applications described here. They are not crash-rated. If your project requires certified anti-ram performance to ASTM F2656 or IWA 14-1, we will say so and refer you to a rated manufacturer.

The paint is already faded on ours. Do I have to replace them?

Usually not. A bollard cover slides over the existing post and restores high-visibility colour in minutes without a crew or a repaint. Replace the post when it is bent or rusted through, not when it has just lost its colour.
