HiSec Louvre LPS 1175 A1 (SR1) Security Fencing
)
)
The system is certified to LPS 1175 Issue 8 A1 (SR1). Its closely spaced mesh helps deter climbing, while the louvres provide screening where privacy and control of external sightlines form part of the site’s security requirements.
Mesh construction and screening
HiSec Louvre uses 4 mm vertical and horizontal wires with a mesh aperture of 76.2 × 12.7 mm. Panels are secured using 40 × 5 mm clamp bars, with post sizes matched to the fence height.
Louvres are installed at 4-inch intervals, allowing screening to be configured around operational requirements. Options include retaining vision gaps or installing louvres to a selected height within a taller fence.
This flexibility allows the perimeter design to balance screening with visibility where observation through the fence is required.

Protective finish
Posts, panels and painted ancillary components receive a protective zinc layer and an electrostatically applied polyester powder coating to BS 1722-16. Enhanced coating systems, including marine coatings, are available for more demanding environments.
Regular washing and prompt repair of coating damage help maintain the protective finish and extend service life.
