CLD SECURUS™ SPECIFICATION

Immensely versatile, incredibly hard wearing and the first line of defence in high security fencing systems, Securus™ is the number one choice for everywhere from schools and business parks right up to police stations, secure units and Ministry of Defence facilities that require a dedicated level of security fencing. 

The 4mm welded steel wires that form each mesh panel are extremely difficult to climb over, and with each panel fixed to a continuous flanged steel post using non-removable shear nuts, the strength of Securus™ ensures a great defence from vandals and intruders and it is ready to be upgraded to SR1 should your threat level increase at any point. 

With the flush finish of the panels, there’s no overlapping, so installation is quick and easy. This also makes Securus™ ideal for sports facilities as an alternative to conventional rebound boards. It’s available in a range of RAL colours too, so you can match it with your organisation’s colour scheme. 

FINISH

Our welded steel wire mesh fencing panels are galvanised and polyester powder-coated after stringent cleaning and treatment to give a well-adhered coating of 60 microns. Or available as galvanised only which is a high aluminium content galvanising giving four times the life of BS 443. This finish is free of the sharps and irregularities found in the hot dip galvanising process. RAL range of colours available.

Graeme F.
Terry and Sam have done some really fabulous work for us. Totally reliable and give a full service experience for the customer. Will always go the extra mile to make sure the job is just right.
Ruth C.
Very pleased with the job. Very polite worker.
Sam K.
I couldn’t be happier with my new fence! From start to finish, the team was professional, efficient, and attentive to every detail. They offered expert advice on the best materials and design for my property, and the installation was seamless. The quality of the craftsmanship is outstanding, and it has truly transformed the look of my garden. I highly recommend this company to anyone looking for reliable, high-quality fencing. Excellent service and amazing results!
Mrs C.
Great and efficient response to a post that needed replacing. Thank you Terry.

Excellent service, good quality panels, and with free delivery worked out cheaper than Wickes!
Paul T.
Terry in Plymouth did a great job installing my 7m fence in difficult terrain,will use again soon,thank you Paul..
Claire A.
Fantastic service from start to finish. Terry was professional, knowledgeable, and kept me well informed throughout the entire process. The job was highly labour-intensive, as all materials had to be carried in and the old fencing removed from a very awkward location in relation to their van, yet nothing was ever too much trouble. Terry and his co-worker Samantha are absolute grafters who worked incredibly hard, and the results speak for themselves. I’m extremely happy with my new fencing and wouldn’t hesitate to recommend them.
Sam C.
Brilliant service and great quality. Will be using them again as required.
Laura S.
Terry from Knight Fencing completed a 22m 6ft high fence and gate installation for us in April 25. From the initial quote Terry went above and beyond to suggest clever solutions to how we wanted the fence put in, eventually helping us to settle on a trellis to keep the view from the end of the garden. When completing the work he and Sam arrived promptly and worked so hard all day to get the work done. They have done an incredibly professional job, the fencing looks fantastic and they left the garden, if anything, tidier than it was before they arrived! I would highly recommend them and thank you for doing such a great job, we can now enjoy the garden without worrying about our dogs escaping!
Martin D.
Straightforward job but very efficiently done. The team arrived while we were out but contacted us by phone and were happy to carry on as requested.
