High Security

View Range
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

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.

RMS Pedestrian Fencing

View Range

Pedestrian fencing is designed to guide foot traffic toward safe crossing points and discourage unsafe, unplanned access to roadways at high-risk areas. It is manufactured to meet NSW Roads & Maritime Services (RMS) specifications and complies with relevant Australian Standards.

Typically installed along road medians and verges, this safety barrier is engineered to withstand low to moderate vehicle impacts while maintaining structural performance and safety.

Each panel is constructed from robust steel components and securely connected to posts using nut and bolt fixings. In the event of a collision, the panel is designed to collapse as a single unit, reducing the likelihood of individual components detaching and posing a risk to pedestrians or vehicle occupants.

  • Road Intersections
  • Streetscapes
  • School Zones
