A 358 fence is a high-security welded mesh fence designed to provide strong protection while maintaining excellent visibility. It uses a special small-aperture mesh structure that makes climbing, cutting, and forced entry extremely difficult.
Also known as 358 mesh fencing, 358 anti climb fence, or 358 security fence, this fence provides high security for prisons, military facilities, airports, data centers, and industrial sites.
Unlike traditional fences, the 358 mesh fence combines anti-climb performance, anti-cutting protection, durability, and clear visibility. Its narrow openings prevent people from getting footholds, while the strong welded wire structure provides long-term security.
What is 358 mesh fencing?
358 mesh fencing is a high-security welded wire mesh fence with extremely small openings designed to prevent climbing and unauthorized access.
The name “358” refers to the mesh size:
- 3 = 3 inches (76.2 mm) wire spacing vertically
- 5 = 0.5 inches (12.7 mm) wire spacing horizontally
- 8 = 8 gauge wire diameter (approximately 4 mm)
The standard 358 mesh opening measures approximately 76.2 mm × 12.7 mm. Because the openings are very narrow, fingers and toes cannot easily pass through the mesh, making it almost impossible to climb.
A typical 358 welded mesh fencing system consists of:
- High-strength welded wire mesh panels
- Steel posts
- Security fixings or anti-tamper bolts
- Protective surface coatings such as hot-dip galvanizing and powder coating
This structure creates a reliable anti climb mesh fence solution for high-security applications.
Why is it called 358 mesh?
The name 358 comes from the three key dimensions of the wire mesh: opening size and wire thickness.
The term is widely recognized in the security fencing industry because it provides a quick way to identify this specific mesh configuration.
| Specification | Meaning |
| 3 | 3 inches (76.2 mm) vertical opening |
| 5 | 0.5 inches (12.7 mm) horizontal opening |
| 8 | 8 gauge wire (approx. 4 mm diameter) |
Compared with standard welded mesh fences, the 358 mesh design has much smaller openings. This gives it several advantages:
- Difficult to climb: The small openings provide no foothold.
- Difficult to cut: More wires are required to create an opening.
- High visibility: The fine mesh allows security monitoring through the fence.
- Strong structure: The welded panels resist impact and deformation.
Why is 358 security fence perfect for safety?
358 security fence provides one of the highest levels of protection among welded mesh fencing systems.
Its design focuses on preventing common security risks, including climbing, cutting, and forced entry.
Excellent Anti-Climb Performance
The biggest advantage of a 358 anti climb fence is its climb-resistant design.
The 12.7 mm narrow openings are too small for hands and feet to grip. Unlike chain link fences, there are no diamond-shaped gaps that can be used as climbing points.
This design makes 358 anti climbing fence ideal for areas that need to prevent unauthorized access.
Strong Anti-Cutting Protection
The heavy-duty wire and welded construction make the fence difficult to penetrate.
A small mesh opening means an intruder cannot easily insert cutting tools between the wires. This provides better protection than many traditional wire mesh fences.
High Visibility for Security Monitoring
Although the mesh provides strong protection, it does not create a visual barrier.
Security personnel and surveillance cameras can maintain clear visibility through the panels, which is important for:
- Perimeter monitoring
- CCTV systems
- Security patrols
Long Service Life
358 security fences are usually manufactured with corrosion-resistant finishes, including:
- Hot-dip galvanizing
- Galvanized + powder coating
These treatments help the fence withstand outdoor environments, rain, humidity, and temperature changes.
