Kent Based Alexandra Security Ltd has unveiled the Protek Elite Defender, a high-security fencing and gate system approved to LPCB LPS 1175 B3 (SR-2).

Developed to address the biggest installation challenges faced by contractors and installers, the system combines certified attack resistance with a cleaner, more efficient design that enhances both build quality and on-site productivity.

Unlike many traditional high-security systems that require a large labour force, bespoke components or time-intensive adjustments on uneven ground, Protek Elite Defender introduces a more practical approach:

Fewer visible fixings – for a cleaner, more professional finish with fewer potential attack points
Slotted posts – allowing mesh panels to hang from the attack face for faster alignment and easier installation.
Lean labour setup – enabling smaller teams to install runs efficiently, once in place, clamp bars and bolts can be secured quickly from the reverse side.
Optional horizontal clamp bar – configurable as either buried or flush-to-ground to suit varying site conditions – without affecting security rating accreditation.

With the rapid expansion of UK data centres and logistics hubs, demand is increasing for security systems that balance certified protection with practical installation. Protek Elite Defender fencing, single & double-leaf gates up to 5.2m high, provides certified delay against attack, robust anti-climb protection, and tamper-proof fixings, all while reducing installation time, rework, and overall cost.

“Protek Elite Defender was developed in direct response to the challenges contractors face on-site,” said Ross Allen, Head of R&D at Alexandra Security. “Our aim was to make LPCB-approved security simpler to handle and install, without compromising protection.”
