In an era where security is paramount, the 358 fence stands out as one of the most reliable anti-climb, high-security fencing solutions available. Designed to prevent intrusions, vandalism, and unauthorized access, this welded mesh fence is widely used in prisons, military facilities, airports, data centers, and high-risk commercial properties.
But what exactly makes the 358 fence superior to other security fences? How does it work, and where should it be installed? This comprehensive guide covers:
What is a 358 Fence?
The 358 fence (also called “358 mesh fence” or “anti-climb prison fence”) is a welded steel mesh panel designed for maximum security. The name “358” comes from its measurements:
- 3″ (76mm) spacing between vertical wires
- 0.5″ (12.5mm) spacing between horizontal wires
- 8-gauge (4mm) wire thickness
This tight mesh pattern makes it extremely difficult to grip or climb, offering superior resistance to cutting, scaling, and tampering compared to traditional chain-link fences.
Key Features of 358 Fencing:
✔ Anti-climb design – Prevents intruders from gaining footholds.
✔ High tensile strength – Resists cutting and impact.
✔ Durable & long-lasting – Galvanized or powder-coated for corrosion resistance.
✔ Versatile installation – Used for walls, gates, and perimeter barriers.
Benefits of 358 Mesh Fencing
Why do government agencies, prisons, and high-security facilities prefer 358 fencing? Here’s why:
1. Unmatched Security
- The tight 0.5″ x 3″ mesh prevents fingers or tools from gripping.
- Welded joints make it nearly impossible to pry open.
2. Anti-Cutting & Tamper-Proof
- Made from high-tensile steel (8-gauge or thicker).
- Galvanized or PVC-coated to resist sawing and bolt cutters.
3. Low Maintenance & Long Lifespan
- Weather-resistant (rust-proof coatings).
- No sagging or loosening over time (unlike chain-link fences).
4. Aesthetic & Customizable
- Available in black, green, or silver for blending into surroundings.
- Can be combined with razor wire, barbed tape, or electric fencing for added security.
Top Applications of 358 Security Fence
The 358 fence is the go-to choice for high-risk environments:
1. Prisons & Correctional Facilities
- Prevents inmate escapes and contraband smuggling.
- Used in perimeter walls, cell windows, and exercise yards.
2. Military & Government Sites
- Protects army bases, embassies, and nuclear facilities.
- Meets DOD (Department of Defense) security standards.
3. Airports & Transportation Hubs
- Secures runways, baggage areas, and restricted zones.
- Prevents unauthorized drone or human intrusions.
4. Data Centers & Utility Plants
- Guards critical infrastructure (power plants, telecom towers).
- Deters cyber-physical attacks on sensitive facilities.
5. Commercial & Industrial Use
- Warehouses, logistics parks, and high-value storage.
- Schools, hospitals, and public buildings requiring enhanced safety.
358 Fence vs. Other Security Fences
| Feature | 358 Fence | Chain Link Fence | Palisade Fence |
|---|---|---|---|
| Anti-Climb | ✅ Excellent | ❌ Poor | ⚠ Moderate |
| Cut Resistance | ✅ High | ❌ Low | ⚠ Medium |
| Durability | ✅ 20+ years | ⚠ 10-15 years | ✅ 15-20 years |
| Cost | $$$ Higher | $ Lower | $$ Medium |
| Maintenance | ✅ Low | ⚠ Moderate | ⚠ Moderate |
Conclusion: If maximum security is the priority, 358 fencing is the best choice despite the higher initial cost.
358 Fence Installation Guide
Step 1: Site Preparation
- Clear debris, level the ground, and mark post locations.
Step 2: Setting Posts
- Use heavy-duty steel posts (concrete-filled for extra strength).
- Space posts 6-8 feet apart for stability.
Step 3: Attaching Mesh Panels
- Secure panels with high-strength bolts or clamps.
- Ensure no gaps at the bottom (embed in concrete if needed).
Step 4: Adding Toppings (Optional)
- Razor wire, barbed tape, or electric deterrents for extra security.
Professional vs. DIY Installation
- DIY possible for small projects, but professional installation recommended for large-scale security needs.
