SR1 Security Fencing for Commercial and Industrial Sites

If you are looking for SR1 security fencing in Essex, Collinson Fencing can discuss your perimeter security requirements for a commercial or industrial site. Based in Laindon near Basildon, we welcome enquiries for projects across Essex, London, Kent and Hertfordshire, as well as other areas of the South East and wider UK where the project is suitable.

SR1 is a security rating associated with LPS 1175, a standard used to assess resistance to defined attempts at forced entry. Where a project specification calls for SR1, it is important to confirm that the proposed product has the appropriate certification and is installed in the configuration covered by that certification.

Whether you are planning a new development, upgrading an existing boundary or working from a security consultant's specification, we can discuss the requirements, site conditions and next steps for identifying a suitable fencing system.

What Is SR1 / A1 Security Fencing?

SR1 is a designation used in earlier editions of LPS 1175. A1 is a classification used in Issue 8. These classifications belong to different editions of the standard and should not automatically be treated as interchangeable. Always refer to the rating and standard edition stated in the product's certification.

When a specification refers to SR1, check whether it requires an earlier edition of LPS 1175 or accepts an Issue 8 A1-rated product. Do not rely on the rating name alone: confirm the exact certificate, product configuration and project requirements with the specifier.

Not every steel, palisade or mesh panel fence is LPS 1175 rated. Certification applies to the assessed product and its permitted configuration, not to a general style of fencing. The actual product and installation details must meet the project specification.

Where Can SR1 Security Fencing Be Used?

Depending on the site's risk assessment and specification, certified SR1 security fencing may be considered for commercial and industrial perimeter projects. The appropriate system depends on the required level of protection and the certification of the specific product being proposed.

Potential applications may include:

  • Commercial premises and business parks
  • Industrial units and warehouse boundaries
  • Distribution and logistics facilities
  • Operational sites requiring specified perimeter protection
  • Commercial developments with security requirements
  • Projects where an architect or security consultant specifies a tested system

These are examples only. The project's risk assessment and security specification should determine the required rating and product.

Choosing the Right SR1 Security Fence

When considering SR1 fencing, assess the complete perimeter rather than the fence panels alone. The proposed system must suit the site's layout, ground conditions, access points and security objectives, and must match the relevant product certification.

Important considerations include:

  • Product certification: Confirm the exact LPS 1175 classification and the product configuration covered.
  • Fence height and layout: Select a system that meets the project specification and site requirements.
  • Gates and access points: Ensure that entrances and gates are considered as part of the overall perimeter design.
  • Ground conditions: Consider foundations, gradients and the proposed installation method.
  • Future maintenance: Allow for the ongoing inspection and maintenance requirements of the installed system.

If an LPS 1175 rating is required, confirm the certificate, permitted configuration and installation requirements before ordering or installing the system.
