358 Anti-climb Mesh
Rigid Mesh Fencing
358 Anti-Climb Rigid Mesh is a high-security fencing system designed for sites requiring enhanced perimeter protection. The name "358" refers to the mesh configuration of 3-inch × 0.5-inch apertures and 8-gauge (4mm) steel wire, creating a robust barrier that is virtually impossible to climb or cut. Proven in prisons, schools, data centres, airports, and critical infrastructure, 358 mesh fencing delivers superior security while maintaining excellent visibility for surveillance, monitoring, and site safety.

Key Features and Benefits
Anti-Climb & Anti-Cut Protection: The narrow, finger-resistant mesh apertures and 4mm wire construction create a highly secure barrier that is extremely difficult to climb, penetrate, or cut with conventional hand tools. Designed for high-security environments, 358 mesh fencing provides effective protection against vandalism, intrusion, and unauthorised access.
Exceptional Stability: The rigid panel design and low wind resistance provide exceptional stability in demanding environments. This makes 358 Anti-Climb Rigid Mesh ideal for high-security fencing applications, including electronic detection systems, perimeter intrusion detection, rooftop protection, and elevated walkways where a robust, self-supporting security barrier is required.
Visibility without Compromise: Despite its narrow mesh apertures, 358 Anti-Climb Rigid Mesh provides excellent visibility across the fence line, allowing unobstructed views for CCTV surveillance, perimeter monitoring, and security patrols. This combination of high security and clear sight lines makes it an ideal fencing solution for prisons, schools, data centres, airports, and critical infrastructure.
Long-term Durability: Designed for demanding commercial, industrial, and high-security environments, 358 Anti-Climb Rigid Mesh Fencing delivers long-lasting, low-maintenance perimeter protection. Its robust steel construction is engineered to withstand harsh outdoor conditions, helping to reduce maintenance costs and maximise service life. For added peace of mind, Hampden backs the system with a 5-Year Warranty.
Unique Double Vertical Design: The innovative Double Vertical wire configuration provides enhanced strength and rigidity compared to conventional welded mesh fencing systems. This robust design improves resistance to impact and intrusion while maintaining excellent visibility through the fence line, delivering a strong and secure perimeter solution without compromising sight lines.
Galvanised After Fabrication: 358 Anti-Climb Rigid Mesh is hot-dip galvanised after fabrication, ensuring complete coverage of all welded joints and exposed steel surfaces. This superior finishing process provides enhanced corrosion protection and helps maintain the fence's appearance and performance over time.
Outstanding Versatility: 358 Anti-Climb Rigid Mesh is a versatile security fencing solution suitable for applications ranging from prisons, military facilities, power infrastructure, and data centres to commercial developments and architectural projects. Combining strength, security, and clear visibility, the system can be tailored to specific project requirements, with custom panel sizes and black steel finish options available.
