Sliding Gates

Our cantilever gates have earnt Frontline Automation an excellent reputation within the commercial market. The cantilever gate is our speciality and is essentially a bespoke product which we have based around established design features. Although the product itself is essentially a pre-designed item, the finished product is designed and then manufactured with the clients individual needs in mind.

Sliding gates have become increasingly popular over the years as they offer a much higher level of security to swing gates - Especially against unauthorised access by intruders 'ramming' the gate system.

Cantilever gates are often more popular than the tracked sliding gates, for a variety of reasons. Cantilever gates have no ground track, which leaves the roadway free from rails and usually saves cost on groundworks. The lack of the groundtrack/wheels combination also means issues are not experienced when installed in a loose roadway surface where gravel or stones may fall into the groundtrack, causing an obstruction for the wheels. They are also ideal when the road surface is uneven, where a tracked gate would not operate efficiently/correctly.

The cantilever gate is fully self-supporting and installation is a relatively quick and simple process. Foundations are required for the two posts (motor post and receptor post) and those posts are bolted onto the foundations. The gate operator/drive and controls are enclosed within a steel housing on the motor post. This adds to both the safety and security of the system, and helps protect the system against vandalism.

There are a wide range of standard designs for the Cantilever gate which would compliment both modern and traditional styles, and to various security levels. All of our Cantilever Gates can be custom designed to match your requirements.

For the commercial client in particular, our cantilevered gates act as the ultimate deterrent against intruders or unwanted visitors and can come with additional anti-climb features such as barbed wire, saw tooth, rotating anti-climb and anti-climb mesh infill.

Turnstiles, Pedestrian Gates and Infill panels can be designed/Installed to compliment the system and/or allow for safe pedestrian entry/exit.

Cantilever Gates
Standard Bar Infill

One of our most popular, standard designs, the cantilever gate leaf itself is constructed from a fully welded rectangular hollow section frame and is then infilled by fully welding 50xxx25mm ERW rectangular section which is mounted vertically at a 150/170 mm pitch. Various additional security measures can be added, and the most popular would be to add mesh panels to both assist with safety and security.




Palisade Infill Cantilever Gate
Palisade Infill

Popular with a number of our larger, high-profile commercial clients, our standard design cantilever gate would be infilled with either Triple Point or Ultra Pale round nosed pales.

Each individual pale is affixed using M8 ultra bolts and finished off with tamper-proof cone nuts. The bolt head lies flat against the rail to maximize security and deter vandalism.

 


Mesh InfillMesh Infill

Placed within the cantilever gate frame in pre-determined sections, 358 Heavy duty security steel mesh, otherwise known as 'prison mesh' is extremely popular. It can, in some applications, be lighter and less imposing than the palisade infill, and also adds an extra safety aspect as no person can get their arm through gaps in the gate leaf, reducing the likelihood of an accident.

 

 


Finish

To prevent any corrosion of the Cantilever gate frame/infill, it is standard practice for the following process to be used:
All steelwork will be grit blasted to SA2.5, hot zinc metal sprayed to 50 micron, pre-heat and etch before being polyester powdercoated to a 50 micron minimum (where the gate leaf is too large to be polyester powdercoated, a two pack polyurethane paint finish will be used instead). Standard RAL colours are easily available, along with a variety of others (upon request) and we would usually apply a finish of 30% gloss, although full gloss/matt are also available.

Gate Safety Controls and Maintenance

BS-EN13241-1 is the safety standard for installation, testing and ongoing compliance of automatic gate, door and barrier systems. The standard has been in force in the UK since February 2008 and all new gate systems installed should comply with the standard.  In short, the standard is designed to protect you, the end user, from risks associated with entrapment between parts of a moving swing or sliding gate. The standard covers both commercial and residential systems and stipulates the following:

1. A swing (hinged) or sliding gate, when colliding with an obstruction, must exert a force of less than 400N before the drive unit stops due to detection of an obstacle.

2. The gate must then reverse to safely clear the obstruction within 0.75 seconds.

3. The entire leading edge of a swing or sliding gate, up to a height of 2.5m, must be fitted with an active obstacle detection system.
4. The obstacle detection system must be tested and accredited to another standard, BS-EN1760-2 that governs quality, durability and failure monitoring, to ensure that the gate will not function unless the safety system is in good working order.

Fitment of safety equipment, and maintenance of, is an integral part of all automated systems and are essential in order to comply with the following regulations:

 BS EN 12978:2003     Safety devices, requirements and test methods
 BS EN 13241-1          Harmonised Product Standard
 BS EN 12445:2001     Safety in use of power operated doors. Test methods  
 BS EN 12453:2001     Safety in use of power operated doors. Requirements
