Zaun’s HiSec 358 SR1 is a high-security welded mesh fencing system manufactured using the 358 mesh configuration (76.2 x 12.7 mm aperture with 4 mm wires). The tight mesh pattern provides anti-climb performance and significant resistance to cutting and attack, making it suitable for sites requiring enhanced perimeter protection and Secured by Design compliance.

The system is independently tested and certified to LPS 1175 Issue 8 Security Rating A1 (SR1) and is suitable for projects requiring LPCB approval. It conforms to BS 1722-14: Category 4.

Typical applications include schools, custodial environments, utilities infrastructure, and other sites requiring a robust physical security barrier.

System Description

Mesh configuration: 358 welded steel mesh
Standard panel heights: 2.0 m, 2.4 m and 3.0 m
Standard panel width: 2515 mm
Maximum single panel height: up to 5.2 m
