The 358 anti-climb mesh fence, also known as "prison mesh" or "security mesh," is a high-strength steel barrier designed to prevent unauthorized climbing and intrusion. Its name comes from its specific mesh dimensions—3" x 0.5" x 8 gauge—which create small, tight openings that are difficult to grip or scale. This makes it highly effective for perimeter security in prisons, military sites, airports, and high-risk commercial properties.
Constructed from heavy-duty galvanized or powder-coated steel, the 358 fence resists cutting, bending, and corrosion, ensuring long-term durability. The welded mesh panels are reinforced with robust frames, making them nearly impossible to dismantle without specialized tools. Unlike chain-link fences, its tight grid pattern eliminates footholds, deterring climbers more effectively.
Why Is It Called 358 Mesh?
The name "358 mesh" comes from its specific wire gauge and spacing measurements, which define its anti-climb properties. The numbers 3, 5, and 8 refer to the fence's 3mm wire thickness, 50mm (5cm) spacing between vertical wires, and 80mm (8cm) spacing between horizontal wires. This tight, narrow grid pattern makes it extremely difficult to grip or climb, earning it the nickname "anti-climb mesh" or "prison mesh."
Originally developed for high-security facilities like prisons and military sites, the 358 designation became an industry standard for this type of fencing. Over time, the name stuck, even as variations emerged. The numbering system helps professionals quickly identify the fence’s specifications, ensuring it meets security requirements. Its effectiveness in preventing intrusion has made 358 mesh a preferred choice for critical infrastructure worldwide.
What Are the Advantages of 358 Anti-Climb Fence?
The 358 anti-climb fence offers superior security and durability, making it a top choice for high-risk facilities. Its tightly spaced 3" x 0.5" mesh design prevents intruders from gaining footholds or handholds, effectively deterring climbing attempts. Unlike chain-link fences, the small openings make cutting or spreading the wires extremely difficult, enhancing resistance to forced entry.
Constructed from heavy-duty galvanized or powder-coated steel, this fence withstands harsh weather, corrosion, and physical attacks, ensuring long-term reliability. The rigid welded mesh panels, combined with strong framing, provide structural integrity, preventing bending or collapse under pressure.
Additionally, the 358 mesh allows for clear visibility and airflow, making it ideal for surveillance-sensitive areas like prisons, airports, and military bases. Its modular design enables easy installation and customization in height and strength. When combined with barbed wire, electric fencing, or anti-tamper coatings, it becomes nearly impenetrable. These features make the 358 anti-climb fence one of the most secure perimeter solutions available.
