Lochrin FlatGUARD™ SL1 - SR1 Weldmesh


Suitable for use in most applications where perimeter security is required, such as police facilities, airports and ports, data centres, industrial and commercial sites creating a high security physical barrier.


AN LPS1175 A1 (SR1) rated mesh fencing system. With a heavier gauge of wire than standard mesh systems, the panel offers greater cutting resistance to vandals and is suitable for use in applications where security is required but without creating an obtrusive and intimidating barrier, the panel is designed to be a strong yet resilient fencing system, it is also capable of blending into its environment and enhancing the surroundings.

Tested to A1 by LPCB against LPS1175 standards and offering at least one minute delay to persistent attack using category A tools such as cable cutters, engineers hooks, glass cutters and pliers, the system is ideal for a range of applications where higher security demarcation is required.

The system is ‘Secured By Design’ and conforms to BS1722 Part 14 carrying full certification to LPS 1175 Security Rating A1 Issue: 8 as featured in the BRE Red Book. LPS 1175 is the requirements and testing procedures for LPCB approval. ‘LPS’ stands for ‘Loss Prevention Standard’ and LPS 1175 is one of many standards by the LPCB ‘Loss Prevention Certificate Board. The LPS 1175 standard focuses on physical security including security fencing, with ratings split into different security ratings, with test requirements of ascending intensity. These are measured in terms of attack tools and also time available to the attacker. Once tested and approved, security rated products are entered into the LPCB Redbook, which is a key reference for specifiers, regulators, designers and end users to select products according to the risks that they and their property face.
