PROTEX 2 B3 (SR2) Security FENCING

ProtEx 2 B3 (SR2) is certified by the Loss Prevention Certification Board to LPS 1175 Issue 8 at B3 (SR2) level. The system is designed to resist forced entry using a defined range of hand tools, providing increased delay and deterrence compared to lower-rated fencing systems. This certification gives contractors and end users confidence when specifying ProtEx 2 fencing for sites requiring a higher level of perimeter security.

The ProtEx 2 system uses 1576 raised steel expanded metal mesh, selected for its strength, visibility and anti-climb performance. The mesh profile offers no finger or footholds, making climbing difficult while maintaining excellent through-vision across the perimeter.

Expanded metal is formed from a single piece of steel, with no welds, joins or strands that can work loose over time. This homogenous construction results in a strong and durable fencing panel that cannot be easily targeted or parted using common tools.

Areas of Application

ProtEx 2 B3 (SR2) security fencing is suitable for sites that require certified perimeter protection with enhanced resistance to forced entry. Typical applications include:

• Utility and energy facilities
• Commercial and industrial premises
• Public buildings and infrastructure
• Data centres and IT facilities
• Council and local authority sites

Proven Performance

ProtEx 2 was specified for the perimeter of Durham Constabulary’s Investigative Hub in Spennymoor, where a certified security fencing system was required that could accommodate site constraints and budget considerations.

Working closely with the appointed contractor, ExMesh Engineering supported the installation of ProtEx 2 to deliver a compliant, secure and practical perimeter solution. Read the full case study.

lps 1175 security ratings

A selection of ExMesh Engineering products are certified to LPS 1175, the recognised UK standard for measuring resistance to forced entry.

Ratings like A1, B3 and C5 define both the duration of attack resistance and the category of tools used during testing. These classifications help ensure the fencing system selected is appropriate for the threat level and operational risk of the site.

Understanding the correct rating is essential when specifying perimeter security for high-risk environments.
