Boom barriers, sliding and swing gates, road blockers, bollards and turnstiles — integrated with ANPR, RFID and access control.
| Requirement | Catalogue-default approach | Engineered approach |
|---|---|---|
| Barrier speed | Chosen from the catalogue spec | Sized to peak vehicles-per-minute so the queue does not back up |
| Duty cycle | Generic | Matched to the cycles per day the gate will really see |
| Crash rating | Applied uniformly or not at all | Specified against a written, per-site threat assessment |

/ The discipline, in detail
How we approach boom barriers & motorised gates.
Vehicle entry is the single highest-throughput interaction at any property. We design barriers and gates to the actual peak flow — opening time, MCBF (mean cycles before failure), safety photocells, loop sensors and obstacle-detection. ANPR or RFID handles the credential read; the barrier handles the physical motion. Crash-rated bollards and road blockers are specified at K4/K8/K12 ratings where the threat profile demands.
Vehicle entry is where security meets traffic flow, and the two are usually in tension. We design the lane sequence — credential read, barrier motion, safety interlock — to the property's peak throughput so a morning rush never backs onto the public road, and we match the barrier's duty cycle and safety sensing to the cycles per day the gate will really see. Crash-rated protection is specified against a written threat assessment per site rather than applied uniformly, and the barrier layer is integrated with access control and ANPR so authorised vehicles flow while everything else is held for a decision — without publishing any of the coverage detail that belongs in the project file.

/ Plan it right
Boom Barriers & Motorised Gates — getting the brief right.
Common mistakes to avoid
- Buying barrier speed and duty cycle from a catalogue instead of the gate's real peak vehicles-per-hour.
- Skipping safety sensing — loops, photocells, obstacle detection — where the barrier crosses pedestrian movement.
- No credential plan — the barrier is only as smooth as the RFID or ANPR read that precedes it, and visitor handling decides the queue.
- Ignoring power backup and the manual-release plan at the gate, so a grid failure leaves the entrance either stuck open or stuck shut.
- Applying crash-rated protection uniformly — or skipping it — instead of specifying it against a written threat assessment per site.
What to share before a quotation
- The gate positions and lane layout (shared privately).
- Peak traffic — vehicles per hour in and out, and the vehicle mix.
- The credential model — RFID tags, ANPR, and how visitors are handled.
- Pedestrian movement around each gate.
- Power availability at the gate, and the integration scope with access control and CCTV.

/ Frequently asked
Boom Barriers & Motorised Gates — what buyers ask first.
How fast should a boom barrier open?
A high-speed boom barrier opens in 1.5–1.8 seconds for corporate gates at 200 vehicles/hour peak; 3-second barriers create queuing at that flow. We size barrier speed to peak vehicles-per-minute, not catalogue spec.
How many cycles per day can a premium boom barrier handle?
Premium barriers (Came, Nice, Magnetic Autocontrol) are rated for 3,000–10,000 cycles per day depending on duty class. A typical commercial gate runs 200–800 cycles. We specify duty class against year-3 expected flow, never to launch-day estimates.
How is the barrier interlocked with the rest of the gate sequence?
Through a documented logic in the access-control platform: ANPR confirms plate, UVSS confirms clean, access database confirms authorised, vehicle-detection loop confirms presence — only then does the barrier open. Loops on either side of the barrier prevent it from closing on a vehicle. Every interlock is programmed and tested at commissioning.
Crash-rated barriers — when are they appropriate?
For embassies, military bases and certain government and corporate HQs where vehicle-borne threat is part of the realistic threat model. Crash-rated bollards (M30, M50) and crash-rated barriers (PAS 68 / IWA 14 standards) are engineered to stop a 7,500 kg vehicle at 50 mph. The civil work for proper anchoring is significant; we coordinate with the structural consultant.
What's the AMC scope for a high-traffic gate?
Quarterly inspection (motor health, gearbox lubrication, induction-loop calibration, beacon and barrier-arm condition), annual full overhaul (motor brushes, gearbox seals, electronic-control replacement schedule), and contracted critical-hours support for high-traffic sites. We hold spare motors, controllers and arms for active deployments.
