Gates and barriers
Automated barrier installation for commercial sites across the UK: new automated barriers, rising arm barriers and car park barriers, with the intercoms, keypads, fob readers and ANPR that raise them, from a free survey to commissioning.

Vehicle control
An automated barrier is an active barrier: a mechanism opens and closes it to allow authorised vehicles through. On car parks, yards and controlled entrances it can be a very successful way of controlling traffic flow and access.
Arm barriers are more affordable than hydraulic road blockers but not as secure. They act as a visual deterrent and are not ram-proof, so where vehicles must be physically stopped, rising bollards or road blockers are the answer.
Bollards and road blockersWhat we install
Within our range you will find all manner of hydraulic and electro-mechanical automatic models, with articulated arm, rigid arm, top and bottom skirted, and bottom-skirted versions.
Automatic arm barriers that lift to let authorised vehicles through controlled entrances and yards.
Entry and exit barriers that control who parks on your site.
Top and bottom skirted or bottom-skirted arms where pedestrians need stopping as well as vehicles.
Fixed and swing height barriers that keep oversized vehicles off car parks and service roads.
Intercoms, keypads, fob readers and ANPR cameras supplied and fitted by Sygma, so the barrier opens for the right people and vehicles.
Old or failed barriers stripped out and replaced with a new automated barrier on the same lane.
How it runs
The engineers who survey the entrance are the ones who install, commission and then maintain it, so nothing is lost between stages.
We walk the entrance with you, measure the opening, check the ground and power, and talk through who and what needs to get in and out.
A system specified for the traffic, the ground conditions and the risk assessment, with the safety devices it needs and a fixed quote.
Barrier, safety devices and loops installed and wired by our engineers, working around your site hours. On a replacement, the old barrier is stripped out first.
Every safety device proven, the system handed over with its documentation and a demonstration for your team.
Planned servicing from day one, with 24/7 call-out from the same team.


Standards and safety
Powered barriers are classed as machinery, like powered gates, and the same safety standard, BS EN 12453, covers both.
Safety in use
Sets the force limits and safeguarding a powered gate or barrier must meet.
Machinery compliance
A powered barrier is a machine, so the regulations for machinery apply to it.
Aware installer scheme
Sygma engineers work to Gate Safe guidance on safe design, installation and servicing of automated gates and barriers.

Questions

Automated Barrier MaintenanceA single arm barrier is usually a day or two on site. Lead times depend on the barrier and operator specified.
No. An arm barrier acts as a visual deterrent and is not ram-proof. Where vehicles must be physically stopped, rising bollards or road blockers are the stronger option.
We supply and fit the access control that raises it: intercoms, keypads, fob readers and ANPR cameras, set up around who and what needs to get in and out.
Yes. We strip out the old barrier and install a new automated barrier in its place, surveyed, specified and commissioned the same way as a new installation.
Yes. Gates, barriers and bollards can be integrated with access control systems, CCTV, intruder alarms and intercom systems to create a fully joined up perimeter security solution.
