Why Our Anti-Vandal Flat Bar Exists, And Why It Matters

At ToughGuard20, we’re seeing a growing number of commercial project teams request the removal or modification of the anti-vandal flat bar in our security fencing range. While we understand the desire for the minimalistic look (and we also understand the concern for maintaining traditional aesthetics), it’s important to clarify why this component exists, and why it’s not as visually disruptive as it might seem.

Sure, many other fencing systems don’t implement it. But we do, because we feel a duty of care. We’re not here to just sell you a fence and walk away. We design for what happens after install, because we’ve seen what happens when systems aren’t built with long-term performance in mind.

The anti-vandal flat bar helps prevent tampering, strengthens structure, and saves installers, and clients, the hassle of repairs and callouts down the track.

Trust us, we’ve seen it. And we’ve designed against it, so you don’t have to deal with it later.

What Is the Anti-Vandal Flat Bar?

The anti-vandal flat bar is a 12mm bar discreetly fixed to the back of the fence panel. While thin in profile, it plays a critical structural role. The bar holds the balusters for key reinforcement and stabilisation, particularly on taller applications like 1.8m high aluminium fencing.

The Anti-Vandal Flat Bar:

Minimises panel flex under pressure
Prevents tampering or forced removal of balusters (which is very common in school projects)
Blocks access to key fixings, making it significantly harder to dismantle or compromise from the outside
Reduces footholds, helping restrict climbing
Supports long-term structural stability
Helps meet security compliance for high-risk, public, or government sites

While MaXGuard provides strong internal X-core support, the flat bar still adds an extra layer of rigidity and tamper resistance. In most cases, we continue to recommend its inclusion, especially in public-facing or compliance-driven projects.

While some suppliers choose to leave it out, we include the flat bar because it serves a critical structural and security function. It’s not about ticking boxes, it’s about building fencing systems that perform reliably long after installation. For us, it’s a non-negotiable part of doing things properly.

Why It Matters for Commercial Projects

In commercial, school, government, and multi-res developments, the risk of vandalism, forced access, or wear-and-tear is significantly higher. That’s why the anti-vandal flat bar is standard in our security-focused designs, it’s not a visual add-on, it’s a function-first requirement.

Removing the flat bar compromises:

Tamper resistance and panel integrity: Increases risk of forced removal or loosening over time
Security compliance: May breach spec-driven or council requirements
Long-term durability and warranty: Removal voids warranty and reduces structural performance in most applications

Aesthetics vs Function: Finding the Balance

At ToughGuard20, we know fences need to look good , but their first job is to perform. The anti-vandal flat bar isn’t just a structural extra, it’s a critical reinforcement feature designed to prevent tampering, stabilise infill blades, and reduce climb points.

Unlike bulky steel bars, our flat bar is thin, streamlined, and powder coated to match the panel, maintaining a clean finish while boosting strength where it matters.

For projects where the bar isn’t preferred visually, we recommend considering our MaXGuard option, which features internal X-Core reinforcement. This allows balusters to stand independently without compromising on strength.

Please note, this internal reinforcement system is exclusive to ToughGuard20, and may not be available or replicated in other products. This is an important consideration when comparing alternatives.

But wherever strength and compliance are non-negotiable, the flat bar stays.

Because fences should do more than look good. They should last. So you can do it once, and do it right.

Final Word

The anti-vandal flat bar is there for a reason, and it’s backed by real-world performance in high-risk environments.

While removing the flat bar may create a more minimal look at first glance, it introduces long-term vulnerabilities. At ToughGuard20, we design systems that last, not just for how they look on install day, but how they hold up for years to come.

FAQ: Do I really need the flat bar?

Q: Can I remove the flat bar for a cleaner look?

A: While some prefer a more minimal aesthetic, the flat bar plays a crucial structural role. It’s powder-coated to match your fence and installed behind the panel, where it reinforces the entire structure without interrupting the face of the design. It’s subtle, not bulky.

Q: Does the flat bar make the fence easier to climb?

A: Not at all, it actually makes climbing more difficult. The flat bar reduces flex and spacing between balusters, minimising footholds. Its slim profile also creates an uncomfortable surface underfoot, discouraging grip or leverage. Plus, it prevents tampering or forced removal from behind, reinforcing the panel where it matters most.

Q: Is it really necessary for all jobs?

A: It’s strongly recommended for most applications, especially high-traffic, school, commercial, or security-sensitive areas. However, for clients who are set on a flat-bar-free look, we offer our MaXGuard system, which features internal X-Core reinforcement, designed to provide structural support without the need for visible bars. Although, we still strongly recommend it.

Q: Why don’t other fencing brands use a flat bar? Aren’t pool fences with the same design compliant without it?

A: Yes, pool fences are designed to meet pool safety regulations, which focus on height, gap spacing, and climb resistance. But they’re typically used in low-impact residential environments, and aren’t built to handle public exposure, attempted tampering, or structural stress over time.

At ToughGuard20, our flat bar is part of a system designed for higher loads, greater spans, heights and long-term durability. This is especially for commercial or security-sensitive sites as it’s not about meeting the minimum. It’s about exceeding expectations where

Q: What happens if I remove it anyway?

A: Removing the flat bar compromises structural integrity and voids ToughGuard20’s warranty, as the panel no longer meets our engineered strength standards. It may also affect compliance with spec-driven or council requirements.

If a builder or architect chooses to exclude the flat bar, we’ll always confirm this with the end client to ensure expectations are clear and there’s no miscommunication around performance or long-term durability.
