Hostile vehicle mitigation barriers that don't look like barriers

When we think of protection against unauthorised vehicle intrusion in public spaces, the image that comes to mind is massive concrete or steel bollards and heavy fencing. For years, that aesthetic defined "security" – brutal, highly visible and not necessarily suited to the character of a given place. Today that is changing. At FANCY FENCE, we show that vehicle intrusion protection systems can be just as effective while working in harmony with open, welcoming architecture.

HVM Certification Standards (ASTM, IWA) – What They Mean

Hostile Vehicle Mitigation (HVM) refers to systems designed to stop a vehicle that may be used as a weapon – for example during a terrorist attack. It protects against the scenario in which someone deliberately and aggressively drives into a protected zone or a crowd.

The two main industry standards are ASTM (American Society for Testing and Materials) and IWA (International Workshop Agreement), developed by ISO. Both classify HVM barriers according to their ability to stop a vehicle of a defined mass at a defined speed. Certification involves crash tests carried out by independent laboratories – this is not a marketing claim, but a verified level of protection.

The reinforced version of the FANCY FENCE system has undergone crash testing at the CTS laboratory in Germany, confirming compliance with both standards. The certified HVM gate can be used wherever documented protection against deliberate vehicle intrusion is required – from diplomatic premises to venues hosting large-scale events such as city squares.

Case Examples: Embassy Entrances, Festival Perimeters

Consider the entrance to an embassy on a prestigious street in the capital. The conventional solution involves barriers visible from a distance that effectively announce the end of open space. FANCY FENCE works differently. The HVM vertical gate can be elegantly lowered beneath ground level at the moment an authorised vehicle enters. For the rest of the time it remains raised, effectively preventing unauthorised access.

Anti-ram gates that retract into the ground also perform exceptionally well in locations that periodically host festivals and mass events. Here, the barrier can remain hidden underground for most of the time, without disrupting residents' daily life or closing off the space. Only when an event takes place does it rise to protect participants. The modular design of FANCY FENCE allows the protection line to be shaped freely, adapting it to the geometry of any given square.

The Psychology of "Soft" Security in Public Perception

Security specialists and architects describe what is known as the fortress effect. Visible, heavy barriers – though effective – can create a sense of threat even in statistically safe locations. A tourist or commercial area surrounded by concrete blocks visually signals danger, which can translate into people avoiding the place and a negative perception of it.

An HVM fence integrated into the site's architecture works in the opposite way. When the system is hidden underground, the space retains its open character and people can move freely. Even when raised, thanks to its modern design, the barrier is less visually intrusive. Sleek metal profiles sit far more naturally in contemporary spaces than bulky concrete bollards. Investors and public facility managers are increasingly recognising that the quality of urban space has economic value. After all, space should exist for people – not the other way around.

Temporary vs. Permanent HVM Solutions for Events

Not every space requiring HVM protection needs it around the clock. Many projects call for seasonal or cyclical use – event squares open for most of the year, government building entrances closed after hours, stadium perimeters active only on match days. Conventional physical barriers are designed with a single scenario in mind – closure – and handle this variability poorly.

Vertical anti-intrusion panels are designed with exactly this flexibility in mind. The vertical movement of the panels enables a smooth transition between open mode, when panels retract below ground, and full security mode, when they rise to form a continuous barrier along the chosen section. It takes just a few seconds to raise or lower the system. Manual operation independent of power supply ensures reliability in crisis situations, while the built-in anti-panic function allows evacuation routes to be opened instantly. Every project can be individually configured for length, finishing materials and panel infill – protection against vehicle intrusion does not have to be a compromise between function and form.
