Product Introduction

358 anti-climb fence, widely known as Prison Mesh. Its name derives from core specifications: 3-inch (76.2mm) horizontal spacing × 0.5-inch (12.7mm) vertical spacing × 8-gauge (4.0mm) steel wire. Fabricated with high-tensile low-carbon steel wire via precision welding. Ultra-tight rectangular mesh leaves no foothold for fingers or toes, making climbing almost impossible. Heavy gauge wires resist cutting and prying attacks. Meanwhile, the open mesh maintains clear visibility for CCTV surveillance. It is the top perimeter security solution for prisons, detention centers and other high-risk sites. The complete system consists of mesh panels, heavy-duty posts and anti-tamper fittings. Y-brackets can be equipped with concertina razor wire for enhanced security. Double anti-corrosion treatment enables stable service in coastal, desert, frigid and other harsh outdoor environments.

Core Advantages

✅   No Climbing  Possibility

        Mesh aperture:76.2×12.7mm, vertical gap only 12.7mm. No space for fingers or toes to grip, structurally preventing climbing attempts.

✅   Anti-Cut & Anti-Tamper 

       Standard 4.0mm high tensile steel wire with full CNC welding. Weld joints feature strong tensile resistance, hard to break by bolt cutters or crowbars against forced intrusion.

✅   Clear Visibility for Surveillance

       Different from solid walls, mesh structure delivers transparent vision without blind spots, convenient for security patrol and real-time CCTV monitoring.

✅   Long Weatherproof Service Life

       Double-layer protection: Hot-dip galvanized base + electrostatic polyester powder coating. UV-resistant, salt & alkali resistant, outdoor service life up to 15–25 years.

✅   Anti-Theft Modular Installation 

       Fixed with dedicated anti-theft bolts and clamping bars to prevent disassembly. Suitable for flat ground and slopes. Height, dimension and post types are customizable. Matching security gates are available.

Production Process

High-strength Q235 steel wire → CNC wire cutting → Automatic resistance welding → Straightening → Pickling & Phosphating → Hot-dip galvanizing → High-temperature electrostatic powder coating → Finished product inspection → Packing & Delivery
