If your project specification calls for LPS 1175 SR2 security fencing, contact us to discuss the site, required specification and installation. The exact product, certification and installation configuration must be checked against your project requirements.

What Is SR2 / B3 Security Fencing?

LPS 1175 is a security testing standard used to assess the resistance of products to defined attempts at forced entry. SR2 is a security rating associated with earlier editions of the standard. Under Issue 8, B3 is commonly associated with the earlier SR2 rating.

In the Issue 8 classification, the letter identifies the tool category and the number indicates the minimum attack-delay time in minutes. The appropriate rating for a site depends on its security requirements, the potential threats, the assets being protected and the project specification.

When a project specifies SR2, check the applicable edition of LPS 1175 and whether the specification accepts an Issue 8 B3 product. Do not assume the designations are automatically interchangeable. Verify the exact product certificate, configuration and project requirements.

Not every steel mesh, palisade or other security fence is LPS 1175 certified. The product, configuration and installation requirements must be suitable for the specified rating.

Where Can SR2 Security Fencing Be Used?

Depending on the product certification and the site's requirements, an appropriate SR2-rated system may be considered for commercial and industrial premises where a defined level of resistance to attempted intrusion is required.

Potential applications may include:

  • Commercial buildings and business parks
  • Industrial premises and warehouse boundaries
  • Distribution centres and logistics facilities
  • Operational sites with defined perimeter security requirements
  • Commercial developments requiring specified security measures
  • Projects where a security consultant or client specifies an LPS 1175 product

These are examples only. The required security rating should be established by the project's security specification, and the selected product must be suitable for its intended use.

Choosing the Right SR2 Security Fence

Selecting security fencing involves more than choosing a panel type or fence height. The perimeter, access points, ground conditions and installation details should all be considered alongside the required security classification.

Important considerations include:

  • Certification: Verify the product's LPS 1175 rating and the configuration covered by its certification.
  • Fence specification: Check the required height, layout and construction against the project documents.
  • Gates and access: Consider how gates and entrances will integrate with the specified perimeter system.
  • Site conditions: Assess ground levels, foundations and the proposed installation method.
  • Overall security: Consider the complete perimeter and how the fencing works with the site's other security measures.

Where SR2 certification is a project requirement, confirm the certification and permitted installation configuration before ordering or installing the system.

SR1, SR2 and SR3 Security Fencing

LPS 1175 includes different security classifications to help specifiers select products that meet their project's defined requirements. SR1, SR2 and SR3 are familiar designations from earlier editions of the standard, with different levels of assessed resistance.

The right option depends on the project's threat assessment and specification rather than simply choosing the highest available rating. Always check the relevant product certification and applicable standard.
