Extra Security 358 Fences – Double Horizontal Wires

The extra high strength double horizontal wire 358 Fence is a formidable barrier designed to provide maximum perimeter security for sensitive areas where standard 358 fencing may not suffice. Building on the robust foundation of the traditional 358 anti-climb and anti-cut mesh, this improved variant introduces double horizontal wires at strategic intervals, significantly bolstering its strength and resilience against breaches. It can be used in critical facilities with the highest security requirements.

Features

Double Horizontal Wires: Positioned at the top edge and at 6-inch intervals, these additional horizontal wires create a more rigid structure, making the fence even more resistant to cutting and deformation.
Anti-Climb Design: The mesh size remains at 3" x 0.5", maintaining its anti-climb properties by preventing the ability to gain finger-holds or use tools effectively.
Enhanced Cut Resistance: With double horizontal wires, the difficulty of cutting through the fence is further increased, requiring more time and more robust tools if an attempt is made.
Optimal Visibility: Despite the added wires, the mesh still allows for clear visibility, ensuring surveillance measures can be carried out without obstruction.
Durability and Longevity: Constructed from galvanized steel and optionally coated for additional weather protection, the fence is built to withstand harsh environmental conditions.
Integrated Security Options: The design can be complemented with barbed wire, razor wire, and electronic security enhancements such as vibration detection systems, further deterring intrusion attempts.

Applications

This enhanced 358 fence is particularly suited for facilities requiring the highest level of security, such as:

Military installations
Correctional institutions (prisons, detention centers)
Critical infrastructure (power plants, water treatment facilities)
High-risk commercial and industrial sites
Border security barriers
