Sentry® Bar Fencing

Sentry Bar Fencing and Gates

Sentry Bar fencing and gates look good in any environment, but are specially designed as the perfect foil for modern architecture. With the same strength and quality of finish as the Barbican range, Sentry Bar offers equal flexibility in a range of seven heights from 1m to 3m and with galvanised or polyester powder coated finishes. A third rail is added for fences 3m high, positioned 500mm above the bottom rail for additional strength. Panels are made with an extra strong 60 x 40mm top and bottom rails.

Seamless design - no visible joins

The 32mm round pales of Sentry Bar are set into the top rail, and pass through the bottom rail to ensure maximum strength, and the heavy vertical steel posts are concreted. The sharp-pointed steel double comb is optional. With easy installation and virtually zero maintenance, Sentry Bar represents almost invincible security.

Sentry�s modern good looks suit many settings

Available with pales at either 150mm or 129mm centres to give a maximum 100mm gap, required for schools and play areas.
Panels can also be stepped or raked to allow for sloping ground conditions.

Above all, Sentry Bar gives you security with clean modern lines, equally at home in town or country.

Gates to match

In addition to matching single, double leaf swing gates and cantilever gates, the Sentry Bar gate can be automated to complete a totally modern fencing system.

Vandalproof Connectors

The jointing system by which the horizontal rails of each panel are slipped over a tough unique steel fitting connected to the post makes it impossible to remove the panel without digging out the posts.

Pointed security comb

Manufactured with a double row of sharp steel points. Height 25mm x 2mm thick. It can be fitted to all panels but is standard on the 1.5m, 1.8m, 2.0m, 2.5m and 3m high panels.


Manufactured from square or rectangular section tube 60 x 60mm or 80 x 60mm according to height, and all hot dipped galvanised as specified to BS EN 1461. A cap on the top of the post gives the finishing touch.

Posts Centres

The main posts are at 3M centres for fences up to 2.5M high and at 2.4M centres for fences 2.9M and 3.0M high.

Post Setting

Each post goes into the ground 700 - 800mm for setting in concrete. On the corners and ends the rails are rivetted to the steel connector attached to the post for extra security.
Level differences on site for the panels are no problem. The maximum level difference per panel is 100mm with standard posts. Longer posts can be used if the level difference is more than 100mm. Special panels can be manufactured and fitted on site to accommodate slopes.


Green, black, white, blue and grey. Other colours on request.
