FAQ: 358 Anti-Climb Mesh Fencing
-
Both 358 Anti-Climb Rigid Mesh and Expanded Mesh are widely used for high-security perimeter protection, but they offer different advantages. A major difference is cost, with 358 Anti-Climb Rigid Mesh typically providing a significantly more economical solution than Expanded Mesh, both in terms of initial installation and whole-of-life ownership costs. In addition to its cost benefits, 358 Mesh delivers excellent anti-climb performance, clear visibility for CCTV and security monitoring, lower wind loading, and easier handling and installation. Expanded Mesh offers enhanced privacy, visual screening, and a solid, robust appearance due to its single-sheet steel construction, making it a strong deterrent in high-vandalism environments. However, its heavier panel construction can require more substantial installation support and handling, particularly on larger projects. For these reasons, 358 Anti-Climb Rigid Mesh is often the preferred choice for many security fencing applications, delivering an effective balance of security, visibility, durability, and value.

Yes, 358 Anti-Climb Mesh fencing and gates can be customised to meet the specific security, structural and aesthetic requirements of a project. Panel heights, widths, post configurations, fixing methods, gate types and finish options can be tailored to suit a wide range of applications, from schools and commercial developments to critical infrastructure and high-security sites. Its proven anti-climb and anti-tamper performance has also made it a commonly specified fencing solution for Department of Corrections facilities and other restricted-access environments.
Depending on project requirements, Hampden can provide a variety of installation configurations, including Typical Modular Assembly and Picture Frame systems. Gate options can be integrated to provide secure pedestrian, vehicle and access-control entry points while maintaining a consistent appearance and security performance across the perimeter.
For highly specialised applications, Hampden can also provide fully bespoke 358 Anti-Climb Mesh fencing solutions. Where standard components are not suitable, systems can be custom engineered, fabricated and, where required, assembled or constructed on-site to accommodate challenging site conditions, irregular geometries, existing infrastructure or specialised security requirements. This capability provides greater flexibility while ensuring the completed installation meets the project's security, structural and compliance objectives.

Yes, 358 Anti-Climb Rigid Mesh can be adapted to accommodate a wide range of challenging site conditions, including sloping terrain, retaining walls, existing structures, confined spaces, rooftop installations, and complex infrastructure environments. For optimal panel alignment and appearance, 358 mesh is generally best suited to gradients no more than 3%, although steeper slopes can often be accommodated through stepped panels or site-specific design solutions.
Where required, Hampden can also provide site-specific engineering design, including PS1-compliant solutions, to ensure the fencing system meets structural, security, and compliance requirements while maintaining the performance and appearance of the finished installation.
-
Before installing 358 Anti-Climb Rigid Mesh, it is important to consider the project's security requirements, site conditions, fence height, wind loading, access requirements, ground conditions for specified post embedment, and any compliance or engineering obligations. Factors such as sloping terrain, retaining walls, existing structures, underground services, and integration with gates, CCTV, perimeter detection, or access control systems can also influence the fence design and installation method.
For larger, high-security, or consented projects, engineering requirements such as post sizing, footing design, and PS1 documentation may also need to be considered. Assessing these factors early helps ensure the fencing solution delivers the required level of security, performance, and long-term reliability.

358 Anti-Climb Mesh is typically available in two configurations: Single Vertical (SV) Wire and Double Vertical (DV) Wire. Both configurations are designed to provide anti-climb perimeter protection; however, the key difference lies in the panel construction. SV Mesh incorporates a single vertical wire at each mesh intersection, while DV Mesh incorporates an additional vertical wire, creating a stronger, more rigid and more secure panel.
The Double Vertical (DV) Wire configuration offers increased strength, stiffness and durability by distributing applied loads more effectively across the panel. The additional vertical wire enhances weld reinforcement and improves resistance to bending, deformation, cutting and impact damage, helping maintain the fence's integrity in demanding environments. These characteristics make DV Mesh better suited to applications where perimeter security, asset protection and long-term performance are critical requirements.
While SV Mesh can be an effective solution for lower-risk commercial, education and industrial applications, DV Mesh is generally the preferred option for high-security environments. Its enhanced structural performance and resistance to damage have seen it widely specified for Department of Corrections facilities and other restricted-access sites throughout New Zealand. Proven across numerous DOC installations, DV Mesh provides an additional level of robustness and confidence where security, reliability and service life are paramount.
