If your project specification calls for LPS 1175 SR3 / C5 security fencing, contact us to discuss the site, required specification and installation. The exact product and its certification must be checked against the requirements of your project.

What Is SR3 Security Fencing?

LPS 1175 is a security testing standard used to assess the resistance of products to defined attempts at forced entry. SR3 is a security rating associated with earlier editions of the standard. Issue 8 introduced a revised classification system, which includes C5 as a security rating.

SR3 is a different classification from SR1 and SR2. The appropriate rating for a site depends on its security requirements, the potential threats, the assets being protected and the project specification.

The LPS 1175 standard and its classifications have evolved over time. SR3 and C5 are classifications associated with different editions of the standard and must not be assumed to be automatically interchangeable. When a project specifies SR3 or C5, check the applicable edition and the exact classification stated in the product's certification.

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 SR3 Security Fencing Be Used?

Depending on the product certification and the site's requirements, an appropriate SR3-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 SR3 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 SR3 or C5 certification is a project requirement, confirm the exact certification, applicable standard edition 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.

Read our guides to SR1 security fencing, SR2 security fencing in Essex and SR3 security fencing. If your specification uses Issue 8 terminology, verify the C5 classification and certificate details against the exact product and project requirements.
