We are a professional manufacturer of 358 Security Fence products, specializing in high-performance perimeter protection solutions. Known as “anti-climb” or “prison mesh,” the 358 Security Fence combines tight mesh openings and heavy-gauge wire to provide maximum security while maintaining visibility. It is ideal for critical infrastructure such as airports, correctional facilities, power stations, data centers, and high-risk industrial sites.
Mesh Design and Anti-Climb Properties
The term 358 comes from its mesh configuration: 3 inches (76.2 mm) horizontal × 0.5 inch (12.7 mm) vertical, made from 8-gauge (4.0 mm) wire. This dense grid spacing prevents intruders from gaining a foothold or inserting cutting tools, making the 358 Security Fence virtually unclimbable and extremely difficult to breach.
Material and Surface Treatments
The 358 Security Fence is constructed from low-carbon steel wire or galvanized steel, offering high tensile strength and rigidity.
- Hot-dip galvanized (zinc coating ≥ 275g/m²)
- Electro-galvanized and powder coated (color options: green, black, grey, white)
- PVC-coated after galvanizing for double-layer protection
These finishes make the fence suitable for various climates and environmental conditions.
Dimensions
Standard panel dimensions for 358 Security Fence include:
- Height: 1800 mm, 2000 mm, 2400 mm, 3000 mm
- Width: 2515 mm, 3000 mm
- Wire Diameter: 4.0 mm (standard), 4.5 mm (heavy-duty options)
- Mesh Aperture: 76.2 mm (H) × 12.7 mm (V)
- Post Profile: Square or rectangular section (e.g., 60×60 mm, 80×60 mm)
Custom sizes can be fabricated to suit project-specific requirements.
Posts and Fixing Accessories
358 fencing panels are mounted to steel posts using anti-vandal security fasteners such as clamp bars, steel clips, and tamper-resistant bolts.
- Square posts: 60×60 mm or 80×80 mm
- Rectangular posts: 60×80 mm
- Post wall thickness: Typically 2.0–3.0 mm
- Post height: Matches or exceeds panel height, embedded or base-plated as required
Accessories such as V-top extensions can be added for barbed wire or razor coil.
Installation and Application
Installation of the 358 Security Fence is straightforward but secure, involving anchoring posts into concrete foundations or surface-mounting with flanges.
- Prisons and detention centers
- Government and military facilities
- Airports and transport hubs
- Utility and power stations
- Data centers and research labs
- Border and perimeter control
