High Security Fence: This type of fence is designed to provide a high level of security for properties. It is made with strong materials and designed to be difficult to climb or break through.
Anti-Climb High Security Fence: This is a type of high security fence that is specifically designed to prevent climbing. It typically features a smooth surface or sharp edges that make it difficult for someone to gain a grip and climb over the fence.
Anti Climb 358 Security Fence: This is a type of anti-climb fence that is made with a specific mesh pattern known as 358. The pattern includes small openings that are too small for fingers to fit through, making it nearly impossible to climb. The number 358 refers to the measurements of the mesh pattern - 3 inches of horizontal space, 0.5 inches of vertical space, and a wire gauge of 8.
Curved 358 Welded Wire Mesh Fence: This is a variation of the 358 security fence that includes curved sections. The curves add an additional layer of security by making it even more difficult to climb over the fence. The fence is made by welding wire together in the 358 mesh pattern.
