358 Fence

The 358 anti-climb fence is named for its imperial dimensions: a 3 in. (approx. 76.2 mm) horizontal opening, a 0.5 in. (approx. 12.7 mm) vertical opening, and 8-gauge wire with an overall thickness of approx. 4.1 mm. It helps prevent climbing by limiting access through these fixed openings.

358 Anti-Climb Fence | High-Security Anti-Climb and Anti-Cut Protection System

Designed exclusively for high-security locations such as prisons, airports, and data centers, this industry-recognized “unclimbable” engineering structure delivers protection far superior to traditional welded fences. It is the preferred physical barrier solution for high-security applications worldwide.

Why Choose 358 Anti-Climb Fence Over Traditional Welded Fences?

Traditional welded fences, with their large mesh openings and simple construction, are highly vulnerable to climbing and cutting, typically meeting only basic security requirements. The 358 anti-climb fence addresses these security vulnerabilities through precision engineering, providing round-the-clock, high-strength protection for your assets and personnel.

✅ Truly Unclimbable Unique Design

Features the industry-standard “3×0.5×8” engineering structure (76.2 mm vertical pitch × 12.7 mm horizontal pitch). The mesh gap is narrower than the width of a finger, leaving no hand or foot holds for climbing. When combined with optional top razor wire or concertina coils, it creates a double anti-overturn barrier.

✅ Superior Anti-Cut and Anti-Damage Performance

· Constructed from 4.1 mm high-strength cold-drawn steel wires with integral welding; tensile strength ≥ 500 MPa

· Resists cutting by common tools such as bolt cutters and crowbars for over 4 minutes (reference: average only 73 seconds for traditional welded fences)

· Special tamper-proof bolt design prevents external disassembly and reduces the risk of illegal intrusion

✅ Exceptional Service Life and Low Maintenance Costs

· Double anti-corrosion treatment: hot-dip galvanizing + polyester powder coating; service life of over 25 years

✅ Excellent Transparency and System Integration

· High-density mesh design provides unobstructed visibility, supporting security personnel monitoring and CCTV operation

· Seamlessly integrates with security systems such as electric fences, vibration sensors, and infrared alarms

· Available in multiple colors to blend with surrounding environments

Optional configurations: Tamper-proof bolts, top razor wire, spikes, bottom anti-dig plates, electric fence integration, 316 stainless steel material
