High Security

A perimeter breach isn’t just a security issue — it’s downtime, investigation, reputational damage, and budget you didn’t plan for.

So, when risk is high,  high security fencing isn’t a “nice-to-have” — it’s your first and strongest line of defence. For over 25 years, Summit Fencing has designed, manufactured, and installed commercial-grade perimeter systems for high-risk environments across Sydney and NSW, including critical infrastructure, and sensitive facilities.

Our security-first approach focuses on anti-climb and anti-cut performance, clear sightlines for surveillance, and robust installation. All systems meet compliance expectations and Australian Standards requirements where applicable — because in government, utilities, and transport projects, “good enough” never is.

Two proven systems lead the category:

• 358 high security fencing
• Palisade fencing (W‑Pale)

What Makes a Fence “High Security”?

High security isn’t a label — it’s the outcome of purposeful design, detailing, and installation. If you’re comparing security fencing systems, look for:

• Anti climb fencing geometry that’s difficult to grip or foothold
• Anti-cut resistance through wire gauge / steel thickness and protective coatings
• Tamper-resistant fixings and secure panel-to-post connections
• Structural integrity engineered for height, wind loading, and impact risk
• Height options and toppings (as required) to increase deterrence
• High visibility to support lighting, patrols, and CCTV monitoring
• A system that integrates cleanly with high security gate systems and access control

This is the difference between a perimeter that “defines a boundary” and one that prevents breach.

Our High Security Fencing Solutions

358 High Security Fencing

Designed for sites where climbing and cutting attempts are a genuine threat, 358 mesh fencing (often called “finger-proof”) uses a tight aperture (75mm x 12.5mm) that limits handholds and tool access. It’s also valued for excellent visibility — ideal when you need CCTV clarity without visual clutter.

Key benefits:

• Strong anti-climb and anti-cut performance
• Zalcote® coated Australian wire for long-term durability
• Clean, secure appearance suited to sensitive public-facing assets
• A smart option for perimeter security fencing around prisons, utilities, and transport facilities

Palisade W‑Pale Fencing

For maximum physical deterrence and a strong “don’t try it” message, palisade fencing remains a benchmark solution. W‑Pale profiles deliver strength and presence, with top styles such as triple-point or single-point to suit the risk level and site requirements.

Key benefits:

• Heavy-duty steel pales built for high-risk perimeters
• Strong posts and rails for robust structural performance
• High visual deterrent for industrial and restricted sites
• Ideal for high risk perimeter fencing where impact, abuse, or repeated testing is expected

Why Choose Summit Fencing?

If you’re sourcing commercial security fencing, you need more than a product spec sheet. Summit Fencing is built around project delivery: design input, fabrication, installation, and ongoing support — with teams experienced in tight timeframes, sensitive areas, and high-risk environments, backed by over 25 years of experience.

You’ll benefit from:

• Turnkey delivery (scope → manufacture → install)
• Custom-engineered outcomes for complex sites
• Integration with gates, barriers, and access control
• Proven experience across Sydney and NSW for high security fencing projects in Sydney and NSW.

Built for Long-Term Performance

Security buyers look beyond installation. Summit Fencing’s systems are selected and detailed for lifecycle value: protective coating performance, weld integrity, consistent panel manufacturing, and straightforward maintenance planning — helping reduce ongoing site burden while keeping perimeter performance reliable.

High Security Gates & Access Control

A secure fence line is only as strong as its access points. Summit can deliver matching gate solutions — sliding, swing, and pedestrian — designed to be integrated with automation and advanced access control systems, featuring matching mesh or palisade infills for a cohesive and impenetrable barrier.
