Security bollards

Security bollards are short, impact tested posts that stop vehicles from reaching footways, forecourts and building lines. They come as fixed, removable, retractable and shallow mount types. This page helps specifiers choose the right bollard for each part of a site.

What is a security bollard

A security bollard is a short vertical post set into the ground to define where vehicles may not go. Impact tested versions are proven to stop a defined vehicle at a defined speed, and they form the most common element of a perimeter and HVM scheme. Rows of bollards guard footways, forecourts, building lines and the approaches to entrances.

Four types cover most sites. Fixed bollards are permanent and suit pedestrian zones. Removable, or lift-out, bollards allow occasional vehicle access for events or maintenance. Retractable bollards rise and fall for frequent controlled access. Shallow mount bollards need minimal excavation and suit streets where buried services rule out deep foundations. The vehicle impact ratings guide explains how each type is tested.

Choosing the right rating for security bollards

Choose the bollard type from how the space is used, then match the impact rating to the threat vehicle and speed. Every type below is rated as a tested system: product, spacing and foundation together.

How security bollards are built

A security bollard is a steel core set into a concrete foundation or a tested socket. The foundation takes the impact load into the ground, which is why the rating always includes it. Spacing between units is set so a vehicle cannot pass between them, and the tested spacing must be kept on site.

Finishes are chosen for the setting: powder coating to a site palette is common, and visibility markings help drivers and pedestrians read the line at night. Removable and retractable types add sockets, locks or mechanisms that need periodic checks by the estates team.

Spacing is part of the rating. Bollards are tested as a row at a set spacing. Widening the gaps on site to suit paving joints can void the protection. Keep the tested spacing.

Combining bollards with other ratings

Bollards rarely stand alone. At vehicle entrances they pair with security gates, and at building entrances with security doors rated to LPS 1175. Pedestrian lanes beside a vehicle line can use security portals for controlled entry, and glazed areas behind the line can be hardened with blast rated curtain walling.

Where security bollards are used

Public spaces use bollard rows to separate crowds from traffic on squares and promenades. High-value retail protects frontages and cash-handling entrances. Government and defence sites guard building lines and car parks, and transport hubs protect forecourts and drop-off zones.

What affects the cost and lead time of security bollards

The number of units and the length of the protected line set the base scope. Foundation type matters: deep foundations need excavation and concrete work, while shallow mount details reduce dig depth but need careful setting out. Ground conditions and buried services can change both cost and programme. Removable and retractable types add sockets and mechanisms, and bespoke finishes add time. Access for plant during installation also affects the programme on constrained city sites. No prices are given here because every site differs.

How to specify security bollards

1. Define the threat. Name the vehicle mass and speed for the approach.
2. Choose the type. Fixed, removable, retractable or shallow mount, matched to access needs.
3. Confirm the tested detail. Keep the tested foundation, socket and spacing.
4. Survey services. Check buried services and levels before fixing the line.
5. Set the finish. Choose colour and markings to suit the setting.
6. Verify the test record. Ask for third-party evidence naming the standard and rating.
