358 fence, also known as anti-climb security fence, is a high-strength welded mesh fencing solution for high-level perimeter protection. Superior to ordinary wire fences, it features a dense no-foothold mesh structure, excellent anti-climb and anti-cut performance, and long-lasting durability. It is the top choice for global high-security sites.
This concise guide covers 358 fence definition, standard specifications, core advantages, common uses, material types and buying tips to help you pick the right security fence for your project.
What Is a 358 Fence?
The name of 358 fence comes from its standard mesh parameters: 3 inches × 0.5 inches × 8 gauge. Converted to metric, the mesh size is 76.2mm × 12.7mm with a 4mm standard steel wire diameter.
It is a fully welded rigid security fence with integrated one-piece mesh panels. Different from flexible chain-link fences, its solid welded structure resists bending, cutting and climbing, delivering reliable anti-intrusion performance for strict security scenarios.
Standard 358 Fence Specifications
Below are mainstream standard parameters; custom sizes are available for special project needs:
– Mesh Opening: 76.2mm × 12.7mm ultra-narrow anti-climb gaps
– Wire Diameter: 3.0mm–5.0mm (standard 4mm/8 gauge)
– Panel Size: 800–2500mm height, 2000–3100mm width
– Surface Treatment: Hot-dip galvanized or PVC powder coated
– Structure: Full welded rigid integral mesh
Core Advantages of 358 Anti-Climb Fence
358 fence stands out in security fencing for its balanced performance of safety, durability and cost savings:
1. Reliable Anti-Climb Performance
The 0.5-inch narrow horizontal gaps leave no finger or toe holds for intruders. It cannot be climbed easily, effectively stopping trespassing and intrusion.
2. Anti-Cut & Anti-Vandal
High-strength steel wire and full welding ensure strong joint tension. It resists cutting with regular hand tools and avoids deformation or damage from vandalism.
3. Weather & Corrosion Resistant
Galvanized and PVC coated finishes prevent rust and aging. It adapts to rain, snow, high temperature and coastal salt spray for all-weather outdoor use.
4. Clear Visibility & Neat Look
The dense mesh retains good transparency for daily patrol and monitoring, with a sleek, modern appearance that fits various site landscapes.
5. Low Maintenance & Long Lifespan
Qualified 358 fence lasts 15–30 years outdoors. It requires no frequent repairs or repainting, greatly reducing long-term maintenance costs.
6. Fast Installation & Customizable
Modular panel and post design enables quick on-site assembly. Custom height, colors and matching razor wire accessories are available for different security levels.
