Jun. 12, 2025 When you're considering how to effectively protect your site, assets and people, it's critical to choose a security fencing system that's difficult to climb and costly to breach, and BONKFC's 358 anti climb mesh (also known as 358 Anti Climb Mesh) is the ideal solution for high security scenarios. Why is it so difficult to climb over? Next, we will provide you with an in-depth analysis of its structural design, core advantages and application scenarios.
358 anti climb mesh is a high-density, strong structure of welded steel wire fencing, its name “358” comes from the inch size of its mesh:
3 inches (76.2mm): the center of the vertical steel wire;
0.5 inches (12.7mm): the center of the horizontal steel wire; 0.5 inches (12.7mm): the center of the horizontal steel wire; 0.5 inches (12.7mm): the center of the horizontal steel wire. 0.5" (12.7mm): horizontal wire center distance;
8 gauge (approx. 4mm): wire thickness.
This precision construction makes it not only strong and durable, but also extremely anti-climbing, commonly used in prisons, military facilities, power stations, airports, government buildings and other high-protection level places.
1. The mesh hole size is so small that it is impossible to insert fingers or toes into the mesh.
358 Anti Climb Mesh's hole size is as small as 12.7 x 76.2mm, which means that an intruder is almost unable to insert his fingers or toes into the mesh to support his body, and thus it is difficult for him to climb with his own strength. This “physical limitation” is the core of its anti-climbing performance. 2.
2. Hard wire, strong resistance to shear
BONKFC's 358 anti-climbing mesh is made of high-strength steel wire welded, even with conventional tools such as wire cutters, wire cutters, it is difficult to cut quickly. Therefore, even if the attacker uses tools to destroy, it will take longer and face higher risks.
3. Optional panel height up to 7.2 meters to create psychological deterrence
Compared to ordinary fences, the 358 fence panels offered by BONKFC can be customized up to 7.2 meters, which is enough to deter the vast majority of people who try to climb. Even at the standard 3 meter height, it is far superior to conventional civilian fences. With the addition of protective components such as roller shutters, crank tops and electric fencing, it is even more difficult to overcome. 4.
4. Structure design does not contain “climbing aid” components
Standard 358 mesh structure is flat, no V-beam, transom and other structures, to avoid providing any support points for intruders to climb with the help of BONKFC supports customized structure to minimize the possibility of being climbed. 5.
5. Matching anti-climbing extension measures
BONKFC suggests customers to combine the following additional measures to further improve the security level:
Install electric fence or PID system;
Additional lighting and camera monitoring system;
Remove trees around the fence, lamp posts and other external supports;
Set up protective top (such as razor wire mesh, wire mesh).
This combination of protection significantly extends the time it takes to break in and improves the overall defense of the site.
For most commercial and public facilities, the height of the fence has a direct impact on security:
Regular Recommended Height: 3 meters;
High Risk Premises: more than 5 meters;
Private Residential or Low Risk Areas: usually no more than 2 meters (some areas are subject to local regulations).
BONKFC can customize the appropriate height and structure for each application to ensure that your project complies with regulations and has the required security.
Even if you have an existing fencing system, you can increase security by installing 358 anti climb mesh. Methods include:
adding 358 mesh extensions (1 meter or more) to the top of the existing fence;
adding roll-up guards or razor wire mesh;
focusing on weak areas (e.g. doorways, corners).
This can effectively upgrade the defense level of the original system without completely replacing the fence, and is a cost-effective way of upgrading.
