Among our flagship offerings, the 358 Security Fence-commonly referred to as Anti-Climb, Anti-Cut, and Anti-Penetration Fence-stands as the global benchmark for high-security perimeter systems. With the increasing demand for critical infrastructure protection, understanding the technical superiority of the 358 system is essential for specifiers, integrators, and security consultants.
What Defines a 358 Fence?
The designation 358 refers to the mesh configuration: 3" x 0.5" (76.2 mm x 12.7 mm) aperture with a wire diameter of 8 gauge (4.0 mm) . This specific geometry is not arbitrary-it is engineered to meet rigorous global security standards, including LPS 1175 (SR1 to SR4), SR2 (Secured by Design), and CE-marked EN 13123-1 impact resistance requirements.
Why 358 Security Fence is Specified for High-Security Areas
1. Uncompromised Anti-Climb Performance
The small 12.7 mm x 76.2 mm mesh aperture prevents any finger or toe hold, effectively eliminating climbing leverage. Unlike welded wire mesh with larger openings, the 358 configuration offers no structural weakness for manual intrusion techniques.
2. High Resistance to Cutting and Attack
Manufactured from 4.0 mm high-tensile steel wire, and reinforced through fully robotic electric resistance welding, the mesh panel exhibits exceptional shear strength. The combination of wire diameter and tight aperture distribution significantly increases the number of cutting attempts required for penetration, providing critical delay time against both manual and mechanical attacks.
3. Structural Rigidity and Forced Entry Defense
The system utilizes heavy-duty galvanized steel framework-typically 50 mm x 50 mm or 60 mm x 60 mm rectangular posts-installed with anti-tamper fixings and concrete-embedded foundations. When integrated with spike tops, razor wire, or detection systems, the barrier functions as a complete physical security layer.
4. Corrosion Resistance and Longevity
All Pauleen 358 systems undergo a dual-layer protection process:
Hot-dip galvanizing (ISO 1461 compliant) providing over 85 µm zinc coating
Polyester powder coating (RAL color options) for UV stability and additional corrosion resistance
This ensures a lifecycle of over 25 years even in coastal or industrial environments.
Applications Demanding 358 Solutions
Through our direct manufacturing capabilities, Pauleen has supplied 358 security fencing for:
Critical infrastructure: power substations, water treatment facilities, telecommunication data centers
Government and defense: military bases, border control zones, courthouses
Transportation hubs: airports, rail depots, seaports

Urban security: schools, stadiums, and commercial perimeters requiring certified protection
Engineering Precision from Our Factory to Your Project
As a manufacturer-controlled supplier, Pauleen offers distinct advantages:
In-house design and engineering: We provide shop drawings, structural calculations, and compliance documentation tailored to project specifications.
Quality assurance: Every panel is inspected for weld consistency, dimensional accuracy, and coating integrity prior to shipment.
Global logistics support: With dedicated export packaging and full container load (FCL) planning, we ensure project timelines are met without compromise.
For high-security perimeters, the 358 Security Fence is not merely a barrier-it is a engineered security system that combines physical deterrence, attack delay, and long-term durability. At Pauleen, with over ten years of specialized manufacturing experience, we continue to set the standard for precision and reliability.
