Mesh Security Fencing: TwinGuard SL1 

The TwinGuard SL1 is a cost-effective yet highly secure tested fencing system, using our durable TwinGuard 868 Mesh Panels with a tested security certificate.

It is a hard-wearing and appealing fence system, used for moderate risk security sites in conjunction with CCTV monitoring such as; police facilities, airports and ports, schools and industrial and commercial premises.

With Barkers’ expertise in the fencing industry, we designed this system with the stringent testing procedure in mind – the latest LPS1175 Issue 8 A1 standard – and engineered our TwinGuard SL1 mesh security fencing system which withstood an experienced attacker with basic hand tools for over 60 seconds.

A simple clamp bar fixed system, coupled with light-weight panels ensures the ease of install, whilst maintaining its aesthetic features as well as its security rating. This security mesh fencing product can be configured to suit any site with features such as base-plated posts and razor wire topping and can be a stepped to cope with sloping ground up to 21°.

Available in heights ranging from 1.8m to 3.0m, this system offers the flexibility to suit specific requirements, and as with all of Barkers’ LPS1175 rated security mesh fencing, a wide range of inward and outward opening swing gates and turnstiles manufactured in-house to match.
