Security Fence Spikes
Protecting assets, infrastructure, and facilities from unauthorised access is an increasing concern across commercial, industrial, and government sectors.
Perimeter security is the first line of defence, and fence toppings such as spikes, barbed wire, razor tape, and our Razorback® Spiked Fence Rail can add a critical layer of deterrence. Razorback is part of the PROMAX™ 358 anti-climb system, providing a fully integrated rail with triangular spikes designed for maximum anti-climb performance in high-security environments.
But while there are more options available than ever before, it’s important to understand the legislation covering security fencing.
In general terms, most security fencing requires a licensed installer, and fences over 2 metres will require council or authority approval. Requirements vary across states, territories, and local councils, so it’s vital to check compliance before installation.
Here are answers to common questions around fence spikes and toppings for commercial and industrial security projects.
How Can I Make My Fence More Secure?
For higher-risk sites, upgrading to engineered fencing systems with anti-climb, anti-ram, and cut-resistant properties is the most effective approach.
Palisade fencing and Promax 358 high security mesh are two of our most sought after products. We also supply a wide range of security fence toppings including razor wire, barbed wire, Bulldog spikes, and our new Razorback® Spiked Fence Rail.
The Razorback rail is a major step forward in topping security. Unlike traditional bolt-on toppings, it integrates 25 mm triangular spikes directly into the steel rail. This means faster installation, fewer components, and a stronger long-term deterrent when paired with our Promax™ system. For large-scale projects, the new 3.0 m wide Promax™ panels further increase coverage with fewer joins and reduced installation time.
Can You Put Spikes On Your Fence?
Yes, in many cases spikes can be installed, but it depends on local regulations. Fences generally need to be at least 2 metres high, and under the Security Industry Act 1997 your installer will require a licence to install spikes or other deterrents.
Our Bulldog spikes are 50 mm high, made from heavy-duty galvanised steel, and suitable for a wide range of security applications.
For facilities requiring an integrated topping system, the Razorback® Spiked Fence Rail provides a compliant, engineered alternative.
What Can I Put On My Fence To Stop Burglars?
Options include barbed wire, flat-loop razor wire, concertina razor wire, Bulldog spikes, and Razorback® rails.
Barbed wire is available in 1.57 or 2.5 mm thicknesses.
Razor wire is offered in short and long barb lengths.
Bulldog spikes provide a simple bolt-on deterrent.
Razorback® rails are installed as part of the anti-climb PROMAX™ 358 system for maximum integration and performance.
Each option offers different levels of deterrence depending on the risk profile and project requirements.

Do Anti Climb/Anti Burglar Fence Spikes Work?
A parliamentary report confirms that properly designed fencing can reduce incidents dramatically:
Arson and break-ins by up to 50%
Vandalism by 71%
Trespass by 88% (in educational institutions)
For industrial and commercial facilities, these reductions translate into fewer disruptions, lower repair costs, and greater peace of mind.
Is it legal to use fence spikes, razor wire or barbed wire?
Legislation varies across states and councils, but in most cases security toppings are only permitted on fences over 2 metres in height, and installation must be carried out by a licensed contractor under the Security Industry Act 1997. Local councils or site authorities may also require specific approvals before work can begin.
In rural and industrial applications, barbed wire is widely accepted and often used to control stock movements without special permission. In urban or commercial areas, however, restrictions are tighter, barbed wire, razor wire, and fence spikes typically require council approval and may be limited to certain fence types or frontage locations.
Compliance should always be confirmed at the project planning stage to avoid costly modifications later.

How Do You Burglar Proof A Chainwire Fence?
Chainwire can be upgraded with anti-climb toppings such as Bulldog spikes or razor wire. Tapered blade extensions can be fitted to support multiple rows of barbed wire or even electrified wires, depending on site requirements.
For sites requiring a higher level of perimeter security than chainwire can provide, PROMAX™ 358 with Razorback® Spiked Fence Rail or palisade fencing with barbed/razor wire toppings deliver the next level of anti-climb performance.
