358 mesh fence, also known as prison mesh or anti-climb fence, is one of the most secure fencing systems available. Designed to prevent climbing and cutting, it is widely used in high-security environments such as prisons, airports, and industrial sites.
This guide explains what 358 mesh fencing is, its key features, and where it is best used.
What is 358 Mesh Fence?
358 mesh fence gets its name from its dimensions:
- 3″ × 0.5″ mesh size (76.2mm × 12.7mm)
- 8 gauge (≈ 4mm) wire thickness
358 fencing is widely used in environments where maximum security and controlled access are required, such as prisons, airports, data centres, and industrial facilities.
This tight mesh design makes it extremely difficult to climb or cut, providing maximum security. Our 358 high security fence systems are designed for demanding environments.
Why 358 Fence is Called Anti-Climb Fence
The small mesh opening prevents footholds and hand grips, making climbing almost impossible, while the thick welded wires increase resistance against cutting tools.
Key anti-climb features:
- Narrow mesh spacing
- Strong welded structure
- High rigidity
Compared to standard fencing options such as 2D double wire fence panels, 358 fencing offers significantly higher security.
358 Fence vs Other Fence Types
Compared to standard fencing systems, 358 mesh fencing is specifically designed for high-risk environments where security cannot be compromised.
| Fence Type | Security Level | Typical Use |
|---|---|---|
| 358 Mesh Fence | Very High | Prisons, airports |
| 2D Fence Panels | Medium-High | Commercial areas |
| 3D Fence Panels | Medium | Residential / light industrial |
| Chain Link Fence | Low-Medium | General use |
You can also explore galvanized chain link fence options for cost-effective solutions.
Key Benefits of 358 Mesh Fencing
358 fencing is preferred for high-security applications because of:
- Anti-climb design
- Anti-cut resistance
- Long lifespan
- Low maintenance
- Strong visual barrier
Due to its design, 358 mesh fencing is often specified in projects requiring compliance with strict security standards. It is often combined with concertina razor wire for maximum perimeter protection.
Coating Options for 358 Fence
358 fences are typically available with:
- Hot dip galvanized coating
- PVC coating
- Powder coating
Choosing the right coating is critical for outdoor performance, especially in environments exposed to moisture, chemicals, or coastal conditions. Galvanized finishes improve durability and corrosion resistance, similar to galvanized steel products used in construction.
What Buyers Should Check Before Ordering
Before purchasing 358 mesh fencing, buyers should carefully review the following specifications:
- Mesh size and wire thickness → determines security level
- Panel dimensions → affects coverage and installation efficiency
- Coating type (HDG, PVC, powder) → impacts corrosion resistance
- Post system and fixing method → ensures structural stability
- Project security requirements → defines whether 358 is necessary or over-specified
Incorrect specification can lead to either unnecessary cost or insufficient security performance.
Working with experienced suppliers helps ensure the correct product is selected based on application and risk level.
What Buyers Should Consider
Before selecting 358 mesh fencing, buyers should evaluate:
- Indoor vs outdoor use
- Required lifespan and maintenance expectations
- Budget vs long-term performance
- Coating and corrosion protection requirements
- Exposure to environmental conditions (humidity, chemicals, coastal areas)
While 358 fencing has a higher initial cost, it often provides better long-term value in high-security applications due to reduced maintenance and superior protection.
