CLD SECURUS SR1™ SPECIFICATION

Few things demonstrate your commitment to protecting your people and property more than a premium high security fencing system. Securus SR1™ welded steel wire mesh fencing is the first level in a formidable defence against intruders that are approved for government use. 

Ideal wherever physical security is paramount: schools, police stations, utility suppliers and even airports, it’s hugely effective in the prevention of everything from vandalism to burglary and even terrorism. 

Strong and durable, the anti-climb mesh fencing is fixed to a steel post with a solid clamp bar for added security. The system also carries certification to Loss Prevention Standards 1175 Security Ratings (SR1) to withstand basic tool attacks, with the ability to easily upgrade to LPS1175 Issue 7 Category 2 (SR2). 

Conforming to BS 1722-14 Category 4 for all fences over 3000mm, it provides eternal confidence that your assets are safe. You can also enhance your system from our Active Anti-Intruder range with Razor Wire and a wealth of other toppings. 

FINISH

Our welded steel wire mesh perimeter security 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.

Knights came highly recommended and didn't disappoint - a first rate job at a fair price. Many thanks
Ian V.
GREAT FENCING!!! We asked Knight Fencing to run 4ft 6"double closeboard with 18" close diamond trellis around our last property (in Bedhampton). This was because we saw what a great job they had done at one of our friend's gardens (in Southbourne). Then another friend saw what we had installed and Knight Fencing did the same for them at 6ft 6" around 3 sides of their back garden (also in Bedhampton). We then had the bottom of our garden re-fenced with 6ft 6" double closeboard when we first moved into our new property (in Purbrook). We are now ready to have the rest of the garden re-fenced and have no hesitation to call Knight Fencing again. Any time anyone has seen these 4 fencing jobs they only say what strong, professional and quality fencing it is.
George N.
Great company! They offer really good advice and customer service, couldn’t fault them!
