358 Prison Mesh Security Fencing

‍

‍

Our 358 steel security fencing features 2500mm post centres. This anti-climb and anti-cut barrier uses 2500mm spacing to maintain structural rigidity and panel alignment in high-security settings.

Widely recognised as the benchmark for high-security perimeters, the "358" design derives its name from its traditional measurements: a tight mesh aperture of 76.2 x 12.7mm constructed from heavy-duty 4mm steel wire. This incredibly dense configuration eliminates finger and toe holds to completely deter climbing attempts, while effectively preventing the use of standard bolt cutters or hand tools. It provides maximum physical containment and asset protection without compromising critical CCTV and security patrol sightlines.

Key Features & Specifications:

• Structural Integrity: the system utilises a precise 2500mm post centre spacing to deliver unmatched panel alignment and high resistance against forced structural deflection.
• Anti-Climb & Anti-Cut Design: The tightly configured 76.2 x 12.7mm aperture denies intruders any hand or foot placement and restricts the physical space needed for breaching tools.
• Enhanced Post & Clamp Fixing: Panels are secured to robust structural steel posts using an anti-tamper, full-length vertical clamp bar and security fasteners to resist prying or leverage attacks.
• Excellent Visibility: The open mesh profile guarantees transparent through-surveillance, allowing site operators to integrate security cameras, lighting and perimeter intrusion detection systems (PIDS) effortlessly.
• Versatile High-Security Applications: Ideally suited for protecting correctional facilities, utility infrastructure, data centres, transport hubs and military estates.
