SECURITY FENCING SPIKES

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.

Approval and installer licensing requirements depend on your location, land use and proposed fence or topping. Confirm the applicable requirements with your local council or approving authority and the relevant licensing regulator 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?

Spikes may be suitable for a compatible security fence, subject to local planning rules, public access considerations and the requirements of the complete fence system. Confirm the proposed height and topping with your local council or approving authority before installation.

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 is an integrated option for a compatible Promax fence system. Confirm the complete system design for your project.

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?

Fence spikes are intended to deter climbing as part of a complete perimeter security design. Their suitability depends on the existing fence, fixing method, site access and risk assessment. A topping alone does not make a fence burglar-proof.

Is it legal to use fence spikes, razor wire or barbed wire?

Requirements vary by state, land zoning, fence location and topping type. There is no single Australia-wide approval rule based only on a fence being two metres high.

For NSW projects, consult the NSW Planning Portal fencing guidance and NSW Police security licensing guidance. Other states and territories have their own requirements. Confirm approvals and the appropriate installer licence before work begins.

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.
