High Security Fencing & Security Rated Systems

High Security Fencing You Can Rely On

At Alexandra Security, we specialise in supplying and manufacturing security rated fencing systems that go beyond traditional perimeter fencing.

Unlike standard fencing, which often serves only as a visual barrier, our high security fencing solutions have been independently tested by the Building Research Establishment (BRE) and approved by the Loss Prevention Certification Board (LPCB). This certification provides you with proven, verifiable assurance that your site is protected against real-world intrusion attempts.

Why Choose Security Rated Fencing?

Standard fencing may look strong, but without independent testing it cannot guarantee resistance to attack. Our LPCB certified fencing systems give you confidence that your perimeter will withstand determined attempts at forced entry using defined sets of tools, within specific timeframes. LPCB security ratings are widely recognised in the industry and help you ensure the right level of protection for your project:

SR1 / A1 High Security Fencing

Designed to resist opportunistic attacks using basic hand tools such as screwdrivers, pliers, and knives, with proven protection for up to 1 minute.

SR2 / B3 High Security Fencing

Provides enhanced resistance against more determined attacks with tools like bolt cutters, claw hammers, and drills, protecting perimeters for up to 3 minutes.

Where High Security Fencing is Essential

Our security rated fencing systems are trusted for some of the UK’s most sensitive and high-value sites, including:

Utilities and Energy Facilities

Data Centres and Data Centre Security Perimeters

Transport and Logistics

Infrastructure and Military Sites

Commercial and Industrial Estates

In these environments, it is not enough for fencing to simply look robust. Our LPCB-approved high security fencing systems deliver evidence-backed protection that meets stringent standards and satisfies insurers, regulators, and clients alike.

Data Centre Fencing Solutions – As data centre sites continue to expand across the UK, the need for effective perimeter protection has become critical. Our data centre security fencing systems are designed to safeguard sensitive assets and server infrastructure from both physical intrusion and opportunistic crime. With options rated both SR1 and SR2, our Protek Elite range ensures your perimeter aligns with the latest LPCB and Secured by Design standards, helping meet planning and insurance requirements while maintaining operational resilience.

The UK’s Police Crime Prevention Initiatives (Secured by Design) programme often recommends the use of security rated fencing for projects where higher levels of protection are required. Choosing LPCB certified fencing can also help projects meet planning requirements and align with insurance conditions.

At Alexandra Security, we supply a range of LPCB-certified high security fencing systems under our Protek Elite brand. If you are unsure which system is best suited to your needs, our expert team can assess your site, understand your operational priorities, and recommend the most appropriate Protek Elite solution. Every site is different, whether protecting utilities infrastructure or securing a high-value data centre perimeter, and choosing the right fencing system is critical.
