Double Skin 358 HiSec Dual Skin | Security Fences | Zaun Fencing

08. HiSec DualSkin

Zaun’s double skin 358 security fencing system, HiSec DualSkin. Specifically designed and developed for applications and sites that require a more robust solution than standard 358 mesh.

The HiSec DualSkin features two layers of the traditional HiSec 358 welded mesh with 76.2mm x 12.7mm wire centres.

These double skin 358 security fencing panels are welded together as standard (a bolted option also available), with the second panel turned 90 degrees. This makes a tight 12.7mm x 12.7mm mesh configuration difficult to cut, scale, and climb.

The small apertures of the mesh section are also small enough to ensure effectiveness against objects such as weapons or contraband being passed through.

The double skin 358 mesh also conforms to BS1722 Part 14 Category 4 and has been extensively used in prisons and by the Ministry of Defense (MoD) to protect high-security assets. The tight pattern of the double skin 358 mesh makes it almost impossible to pass objects or contraband through the fence into restricted areas.


HiSec DualSkin 358 mesh fencing is manufactured from pre-galvanised GalZal® steel wire according to BS EN 10244-2 class A Zn95AL5 standards with a typical thickness in wire diameter 275g/m2 (on a 4mm wire). Fences coated in GalZal® do not require additional powder coating as protection.

Additional coating options are also available; if required, please get in touch with [email protected] for details.

Posts & Fixings

The HiSec double skin 358 perimeter security fencing system features a post and clamp bar configuration, providing a simple and easy installation method. Supplied with through bolts, washers and nuts and installed using either power or hand tools.

Sloping Ground

Panels can be stepped as required on the post. However, on steeper gradients, it is recommended that taller panels are either part-buried or additional posts are used.


Posts are available in different lengths to accommodate panel heights and ground conditions. Additional variations are also available:
