358 High Security Fence China Factory Leading Prison Mesh Suppliers
The 358 High Security Fence, often referred to as the "prison mesh," is an industry-leading perimeter security solution engineered specifically to prevent unauthorized access. Utilizing a tight, small-aperture mesh design, this system eliminates finger and toe holds, making it virtually impossible to climb. Constructed from high-grade low-carbon steel (Q195/Q235), it provides an impenetrable barrier for critical infrastructure where security is non-negotiable.
Designed for extreme durability and long-term performance, the 358 fence excels in resisting shearing and cutting attempts. By combining heavy-duty wire diameters with advanced surface treatments such as hot-dipped galvanizing and powder coating, this fencing system ensures maximum corrosion resistance while maintaining high visibility for surveillance. It is the gold standard for safeguarding sensitive installations across military, government, and industrial sectors.

Frequently Asked Questions
The 358 fence features extremely small mesh apertures (76.2mm x 12.7mm), which are too narrow to allow fingers or toes to gain a grip, making it nearly impossible to climb without specialized equipment.
It uses heavy-duty low-carbon steel wires (up to 5mm) in a tight configuration, which makes it difficult for standard bolt cutters to penetrate the mesh.
Hot-dipped galvanizing combined with a PVC or powder coating is recommended for coastal areas to provide double protection against salt-spray and humidity.
Yes, we offer custom heights from 1.0m to 6.0m and widths from 1.0m to 4.0m to fit your specific site requirements.
Not at all. The flat, evenly spaced mesh design ensures excellent visibility, which is critical for surveillance monitoring and security guard patrols.
The fence is primarily manufactured from high-quality low-carbon steel wires (Q195 or Q235) and supported by rectangular steel tubing for maximum stability.
