358 Mesh Fence Specification | Complete Technical Guide for High Security Fence Systems
When selecting a high-security fencing solution for prisons, airports, military facilities, data centers, industrial plants, or critical infrastructure projects, understanding the 358 mesh fence specification is essential. The technical specifications directly determine the fence’s security level, durability, installation requirements, and long-term performance.
Known worldwide as 358 Security Fence, Anti-Climb Fence, or Prison Mesh Fence, 358 fencing is engineered to provide exceptional protection against climbing, cutting, and unauthorized access. Its unique mesh configuration and robust welded structure make it one of the most widely specified perimeter security fencing systems globally.

What Does 358 Fence Mean?
The name “358 Fence” comes directly from its standard mesh specification.
Standard Mesh Opening
The standard aperture size is:
- 76.2 mm × 12.7 mm
- 3 inches × 0.5 inches
This extremely narrow opening prevents fingers and toes from gaining sufficient grip, making climbing virtually impossible.
Standard Wire Diameter
The most common wire diameters include:
- 3.8 mm
- 4.0 mm
- 4.5 mm
Heavier wire diameters provide greater impact resistance and enhanced anti-cut performance.
Why the Specification Matters
The combination of small mesh openings and heavy-duty steel wire creates one of the highest security levels available among welded wire fence systems.
Standard 358 Mesh Fence Panel Specifications
Fence panel dimensions vary depending on project requirements, security levels, and local standards.
Common Panel Heights
Standard panel heights include:
- 1800 mm
- 2000 mm
- 2100 mm
- 2400 mm
- 3000 mm
For prisons, military facilities, and airports, heights of 2400 mm or above are typically recommended.
Standard Panel Width
The most common panel width is:
- 2515 mm
Custom widths are available for special project requirements.
Horizontal and Vertical Wire Configuration
Typical wire arrangement:
- Horizontal wire spacing: 12.7 mm
- Vertical wire spacing: 76.2 mm
This dense configuration provides superior anti-climb protection while maintaining excellent visibility.
Material Specifications of 358 Security Fence
The quality of raw materials directly affects fence strength and service life.
High-Quality Carbon Steel Wire
Most 358 fence panels are manufactured using premium low-carbon steel wire that provides:
- High tensile strength
- Excellent weldability
- Consistent dimensional accuracy
- Long-term structural stability
Galvanized Steel Construction
Galvanized wire enhances corrosion resistance and improves outdoor durability, especially in humid or industrial environments.
Optional Stainless Steel Material
For highly corrosive environments such as coastal facilities or chemical plants, stainless steel versions can be supplied upon request.
Surface Treatment Specifications
Surface treatment plays a critical role in protecting security fencing against corrosion and weathering.
Hot-Dip Galvanized Finish
Hot-dip galvanization provides:
- Thick zinc coating protection
- Excellent anti-rust performance
- Long-term outdoor durability
Typical zinc coating thickness:
- 60 g/m² to 610 g/m²
Depending on project requirements.
Polyester Powder Coating
Electrostatic powder coating offers:
- Enhanced corrosion resistance
- Attractive appearance
- UV protection
- Wide color selection
Common colors include:
- RAL 6005 Moss Green
- RAL 7016 Anthracite Grey
- RAL 9005 Black
- Custom RAL colors
Dual Protection System
For maximum durability, BDFENCE recommends:
Hot-Dip Galvanized + Polyester Powder Coated
This dual-layer system significantly extends the service life of the fence.
Security Performance Specifications
The primary purpose of 358 fence is perimeter security.
Anti-Climb Performance
The 12.7 mm horizontal opening prevents:
- Finger insertion
- Foot placement
- Climbing attempts
This feature is the reason 358 fence is often called an anti-climb fence.
Anti-Cut Resistance
Heavy wire diameters and dense mesh spacing make cutting difficult and time-consuming, increasing perimeter protection.
Compatibility with Additional Security Systems
358 fence can be integrated with:
- Razor wire
- Barbed wire
- Electric security systems
- Motion detection sensors
- CCTV monitoring systems
This creates a comprehensive security solution for high-risk facilities.
Post and Installation Specifications
Selecting the proper post system is equally important.
Common Post Types
Available options include:
- Square posts
- Rectangular posts
- Security flange posts
- Heavy-duty reinforced posts
Fixing Methods
Typical installation methods include:
- Concrete embedding
- Base plate mounting
- Chemical anchor installation
The appropriate method depends on site conditions and project requirements.
Security Fasteners
Tamper-resistant security bolts and anti-theft fasteners are commonly used to prevent unauthorized panel removal.
