A bollard is a short, sturdy post installed to control vehicle and pedestrian access. Bollards define boundaries, protect storefronts, secure parking areas, and prevent vehicle intrusion into pedestrian zones.

Types of Bollards

Fixed steel bollards are permanently anchored into concrete and provide the highest level of vehicle impact resistance - standard in security perimeters, government buildings, and retail storefronts.

Removable bollards use a locking sleeve embedded in the ground so the post can be pulled for delivery access or emergency vehicle passage, then replaced.

Flexible/delineator bollards are made from high-density polyethylene and deflect on impact rather than resisting - common in parking lots and traffic lanes where accidental vehicle contact is expected.

Decorative bollards combine security function with architectural aesthetics - available in cast iron, steel with ornamental caps, and powder-coated colors to complement building facades.

Sizing & Spec Guide

Standard bollards are 3–6″ diameter and 36–42″ above grade. Spacing for vehicle access control is typically 4–5 feet on center. For ADA compliance, leave at least 36″ clear between posts.

FAQs

1. What is a bollard?

A bollard is a short, sturdy vertical post used to control vehicle access and protect pedestrian areas. They’re installed at storefronts, parking lots, building entrances, sidewalks, and security perimeters. Bollards can be permanent (fixed), removable, or flexible depending on the application.

2. What’s the difference between fixed and removable bollards?

Fixed bollards are permanently set into concrete - best for security perimeters and permanent access restrictions. Removable bollards use an in-ground sleeve that allows the post to be locked in place or pulled out for temporary vehicle access, making them ideal for loading docks, emergency lanes, and event venues.

3. What does bollard mean in traffic safety?

In traffic safety, a bollard defines the boundary between vehicle and pedestrian zones. They protect sidewalks from vehicle encroachment, delineate bike lanes, mark hazard areas, and prevent vehicles from mounting curbs. Flexible bollards deflect on impact to alert drivers without causing vehicle damage.

4. How deep do bollards need to be set?

Standard fixed bollards require a footing depth of 18–36″ depending on diameter and load requirements. A common rule of thumb is setting the bollard one-third of its total length below grade. For maximum vehicle impact resistance, consult ASTM F2656 ratings.

5. How far apart should bollards be spaced?

For vehicle access control, bollards are typically spaced 4–5 feet on center - close enough to block a car (which needs ~6 ft clearance) while allowing pedestrian passage. Emergency vehicle access lanes use wider spacing (10–12 ft) with removable bollards in the gap.

6. Can bollards be used indoors?

Yes. Indoor bollards protect equipment, columns, and rack systems from forklift and cart damage in warehouses and distribution centers. These are typically shorter (24–36″), wider-diameter, and yellow for high visibility.

7. What are decorative bollards used for?

Decorative bollards serve both security and architectural functions at retail storefronts, urban plazas, parks, and historic districts. Available in cast iron, aluminum, and steel with ornamental dome, flat, or acorn caps, often in black or dark bronze finishes.
