Securing a data facility starts with the right data centre fencing system, as different fences solve different security risks. Many rely on 358 mesh fencing to prevent climbing, while palisade fencing discourages intruders before they even attempt it. Chainwire fencing is preferred when enhanced surveillance is planned for sensitive facilities. Let’s understand their utilities and explore key regulations that the P&C Fencing team highlights.
Realise The Need Of The Hour
Physical security is the first principle highlighted by the Australian government in a recent report.
Further, threat assessments underscore that multi-vector attacks, combining social engineering, remote compromise, and, occasionally, physical tampering, amplify the consequences of an unsecured site.So, along with cybersecurity measures, a well-designed data centre fencing strategy delays and deters intruders and, if a situation arises, restricts and restrains them for better screening.
1. 358 Mesh Fencing – The Anti-Climb Gold Standard
One of the most recognised solutions in data centre fencing is 358 mesh fencing, sometimes referred to as ‘anti-climb’ fencing. The name comes from its technical wire specification, which boasts a 3 mm wire diameter and a mesh aperture of around 50 mm by 8 mm, typically.
These measurements remove footholds while still allowing clear visibility for surveillance cameras. And because the mesh wires are welded at every intersection, the structure becomes extremely rigid.
Many operators install 358 mesh fencing around the inner perimeter where server buildings or switching infrastructure are located. Because when steel panels are combined with anti-tamper fixings, cutting through them becomes difficult and time-consuming.
2. Palisade Fencing – Visible Deterrent And Hard Barrier
While mesh fencing prevents climbing, some locations need a stronger psychological and structural barrier. This is where Palisade Fencing becomes valuable.
This fencing system uses vertical steel pales fixed to horizontal rails and mounted on heavy-duty posts. The top of the pales can be designed with pointed or triple-pointed profiles that discourage climbing.
Think of a facility located in an industrial area with heavy vehicle access where palisade fencing serves two important functions:
- It creates an intimidating visual deterrent, signalling that the site is highly secured.
- It forms a robust steel barrier capable of resisting impact and tampering.
For example, thicker gauge steel pales combined with anti-tamper bolts make it extremely difficult for someone to dismantle the fence panels.
3. Chainwire Fencing – Flexible, Cost-Effective Perimeter Control
Not every part of a data centre campus requires the same level of defence. Large facilities often occupy extensive land, including utility zones, cooling systems, and service roads. Chainwire fencing remains a versatile option for such lower-risk perimeters.
Also known as chain-link fencing, this system consists of interwoven steel wires forming a diamond-shaped pattern. It’s quick to install, economical, and provides clear CCTV sightlines.
But it is important to note that standard chainwire can be easier to climb compared with specialised mesh fencing. That’s why modern installations reinforce it by:
- Adding barbed wire or razor wire at the top.
- Using thicker galvanised wire.
- Installing tension rails for structural strength.
These enhancements improve resistance against cutting and climbing while keeping installation costs manageable for long perimeters.
Security Add-Ons for Data Centre Fencing
| Add-On Feature | Purpose | Security Benefit |

| Fence-Mounted Intrusion Sensors | Real-time intrusion detection | Alerts security teams instantly if fencing is cut, climbed or tampered with |
One-Stop Guidance For Securing Data Centres in Australia
If your data centre happens to be located in Australia, P&C Fencing suggests going through these.
- The Security of Critical Infrastructure Act 2018 (SOCI Act) is the primary federal law that sets out obligations for owners and operators of critical infrastructure assets. Notably, it has been amended to extend obligations to certain data storage and related systems. So, if your data centre meets the definitions in the Act, you must understand reporting and risk-management obligations.
- The Critical Infrastructure Security Centre (CISC) provides fact sheets and practical guidance for owners and operators (including risk-management program guidance and specific notes for data storage, access, and control). These fact sheets are a useful, plain-language companion to the SOCI Act.
The Australian Cyber Security Centre (ACSC / ASD) Information Security Manual (ISM) includes a chapter on physical security and other practical guidelines that many data centre operators use when designing their perimeters, access controls, and monitoring. You must remember that the ISM is not law, but it is authoritative operational guidance widely referenced by government and industry.
A Lot Depends On Your Fencing Contractor
Designing an effective perimeter requires careful planning. Ground conditions, surveillance coverage, gate access, and maintenance requirements all influence the final fencing layout. That is why when organisations consult a professional fencing contractor in Sydney, they want top-notch engineering expertise. P&C Fencing partners with leading commercial and government bodies to deliver robust perimeter security solutions. Our team can help you secure your data centre while ensuring compliance with all regulatory and quality requirements.
FAQs
Q. Why do data centres need specialised perimeter fencing?
Data centres store critical digital infrastructure, so physical access must be tightly controlled. Specialised perimeter fencing helps prevent unauthorised entry, protects power and cooling systems, and delays intruders long enough for security teams to respond.
Q. What Not To Do When Securing A Data Centre?
- Don’t assume CCTV alone is a deterrent.
- Don’t add razor/razor coil or electrified lines without checking the law and WHS rules.
- Don’t allow vegetation or landscaping to create climbing aids or hide intrusion.
Q. Do data centre fences need intrusion detection systems?
Many modern facilities install fence-mounted sensors or fibre-optic detection systems that trigger alerts if the fence is cut, climbed, or tampered with.
