What is 358 mesh?

358 is a high security anti-climb mesh fencing system, otherwise known as 358 or prison mesh. 358 provides maximum security for perimeter security fence protection. The mesh aperture of 71mm x 9mm manufactured from 4mm diameter wire makes it extremely difficult to penetrate using conventional hand tools, therefore providing a high delay factor. Whilst maintaining a high level of security, 358 security fencing has a low visual impact on the surrounding environment. The finger / toe-proof mesh aperture makes for a totally secure, superior anti-climb fencing system that’s difficult to cut or climb whilst maintaining a clear level of sight through the horizontal aperture from any angle.

358 Security Mesh is superior quality zinc/aluminium coated Ø4mm high-tensile steel mesh with an aperture size of 71mm x 9mm.

  • 358 refers to the imperial measurements: 3-inch (75mm) centres, the horizontal wires at 0.5-inch (12.5mm) centres and the wire is 8 gauge (4mm dia).

Weld shear strength exceeds AS2423-2002 requirements

  • Resistance welding to AS2423-2002 requirements
  • Zinc aluminium coating to AS/NZS4534—a minimum thickness of 260g/m2 with an average of 300g/m2
  • Average tensile strength—560 MPA

Why is 358 mesh perfect for security and safety?

      • Anti-climb fencing is extremely difficult to climb
      • Highly resistant to normal cutting tools
      • Minimizes visual impact on the surrounds

    Provides a critical clear line of sight for security and camera surveillance
