What Alexandra Security does

Alexandra Security Limited is a UK-based, privately held manufacturer and supplier of high-security perimeter protection systems, founded in 1986 and headquartered in Tonbridge, Kent. The company designs, engineers, and manufactures welded wire mesh fencing, palisade fencing, twin-wire mesh systems, security gates, car park barriers, and temporary construction site solutions under proprietary brands including Protek (mesh and palisade security fencing), SolarGard (solar farm and battery energy storage system fencing), SiteGard (temporary site gates), and CraneGard (tower crane protection). Core technology centres on LPCB-certified security ratings (SR1/A1 and SR2/B3) independently tested by BRE, hot-dip galvanisation and powder coating for weather resistance, patented ProPale bolt head protection, anti-grab tags, and marine-grade coating systems developed for coastal environments.

The company operates an enterprise field sales model with direct engagement from site consultation through CAD design, manufacturing, and installation support, targeting main contractors, sub-contractors, specifiers, architects, and government agencies. It lists on the NBS Source specification platform and maintains an approved installer network, with stock held at its Kent depot for same-day collection and 48-hour nationwide delivery. Revenue is generated primarily through bespoke hardware sales of fencing and gate systems supplemented by consultation and CAD design services, with quote-based pricing tied to project specifications.

The customer base spans utilities and critical infrastructure (Sizewell C Nuclear Power Station, Millbrook Power Station), rail (HS2 Phase 1), government (a confidential 4,000m+ LPCB-rated project in January 2026), renewable energy (Dudgeon Wind Farm, Instavolt, Potash Farm), education, healthcare, sports, and construction sectors. The company holds ISO 9001:2015, ISO 14001:2015, BS OHSAS 18001:2007, SSIP, LPCB, and Secured by Design certifications, and offers a 15-year product guarantee on its mesh fencing systems.
