Tubular round bar security fencing
Sentry Tubular Fencing System | Security Fencing
The Sentry® security fence range of fencing and gates feature a welded semi pale-through-rail construction to combine style with performance and is equally appropriate for contemporary or more traditional settings. Like our Barbican® system, all Sentry® fencing and gate panels incorporate concealed fixings for strength and security.
Pales are spaced to a maximum gap of 100mm to conform to building regulations for anti-trap, making Sentry safe for applications where children may be present.
Sentry® correspond(s) to the generic component/material "steel" in the BRE Global Guide online generic specification(s) "Galvanised steel railings" which achieve(s) a summary rating of B within commercial, domestic, residential, health, industrial, education.
