What Is an Electric Gate System?
Electric gate systems combine physical barriers with automated technology to control who can enter or leave a property safely and efficiently. An electric gate typically consists of a gate leaf or panel, a motor (electromechanical or hydraulic), control electronics, safety sensors, and access-control devices such as keypads, fobs, or intercoms. These systems are used on both homes and commercial sites, from residential driveways and apartment blocks to warehouses, hospitals, airports, and high‑security facilities.
Main Types of Electric Gate Systems
An electric gate system is a motorised entrance gate that opens and closes automatically using electricity or solar power, usually triggered by a sensor or access-control device rather than manual effort. Electromechanical operators typically use screw drives, chains, or rack-and-pinion mechanisms, while hydraulic operators use pressurised fluid to move pistons or arms.
Once activated by a vehicle detector, keypad, fob, intercom, or smartphone app, the operator moves the gate to open or close, with built-in safety and obstruction-detection features to prevent accidents.
Electric gates are classed as machinery in the UK and EU, so they must be designed, installed, and maintained in line with safety regulations and machinery directives to avoid serious injury. Professional installers carry out risk assessments, specify the correct safety edges, photocells, and warning devices, and ensure the system is pressure-tested and compliant.
Electric gate systems come in several core types, defined by how they move and where the motor is installed.
- Swing gates (above-ground and underground drive units)
- Sliding gates (tracked and cantilever)
- Bi‑folding speed gates
- Vertical lift / vertical pivot gates
- Barrier arm gates (rising arm barriers)
These systems use different operators: ram/linear screw arms, underground drives, sliding motors, barrier arm units, or overhead operators, each with specific site and usage strengths. Below is an overview of how each type works and where it fits best.
Swing Electric Gate Systems
Swing gates open like a door, rotating on hinges either inward or outward, using one or two leaves. They are widely used for homes, rural properties, and corporate entrances where there is enough flat space inside the property for the gate to swing freely.
How Swing Gates Work
Swing gates can be driven by:
- Ram (above-ground hydraulic) operators: visible linear arms mounted between the gate post and leaf, powered by hydraulic pistons for high power and durability.
- Linear screw (electromechanical) operators: use a threaded shaft that moves a bracket, generally cheaper and better for lighter aluminium or small residential gates.
- Underground motors: sit in foundation boxes at the hinge line, with an arm attached to the underside of the gate for very discreet but powerful operation.
Typical swing gates open in about 12 seconds, with maglocks and robust frames used to resist wind and forced entry. They can integrate FAAC‑type underground motors, GSM controllers, keypads, intercoms, radio fobs, and even solar panels with deep-cycle batteries for off‑grid operation.
When Swing Gates Are Suitable
Swing gates are best when:
- The driveway is relatively flat and level.
- There is enough internal depth for the leaves to swing without hitting vehicles or buildings.
- A traditional, residential-style aesthetic is desired (e.g., timber, wrought iron, or decorative panels).
They are ideal for:
- Homes and farm or rural entrances.
- Corporate offices or residential‑style commercial properties.
- Sites where moderate security and strong visual impact are important.
However, swing gates are less suited to very steep driveways, extremely windy sites, or tight forecourts where swing clearance is limited.
Sliding Electric Gate Systems
Sliding gates move horizontally, usually parallel to the fence line, making them ideal where there is limited depth or sloping ground that would prevent swing gates from operating. Sliding systems are also preferred for high‑security applications because they are hard to force open and have fewer vulnerable points than swing gates.
Tracked Sliding Gates
Tracked sliding gates run on a ground track, with wheels or rollers attached to the gate moving along this track while a motor drives a chain or rack and pinion. They can be very large; individual gates can exceed 5.5 m openings and 25 m lengths in some industrial settings.
Key characteristics:
- Require a straight, even surface and a well-maintained track.
- Offer strong mechanical simplicity and excellent resistance to forced entry.
- Suitable for both residential and commercial driveways where the ground is flat and space for the gate to retract is available.
Tracked systems are generally more cost‑effective than cantilever gates because the mechanism is simpler and installation is more straightforward.
Cantilever Sliding Gates
Cantilever sliding gates are elevated off the ground and do not need a track across the opening. Instead, the gate frame includes a tubular lower track that slides over post-mounted rollers, with a counterbalance section extending beyond the clear opening.
Key characteristics:
- No ground track: ideal for uneven, sloping, snowy, or debris‑prone areas (gravel, mud, flood‑risk sites).
- Reduced maintenance: fewer ground-level components, less risk of track damage or obstruction.
- High security: gate is supported at both ends when closed, making tampering difficult.
Cantilever gates can reach up to around 12 m in single spans or 24 m when using a pair, making them popular for commercial and industrial entrances, schools, and high‑traffic sites.
Speed and Use Cases
Sliding gates typically move at around 1 foot per second; a 14 ft (approx. 4.3 m) gate might take about 14 seconds to open, though faster motors can reach 3–4 feet per second where required. They are particularly well‑suited to:
- Warehouses, industrial parks, and logistics yards.
- Gated storage and loading bays.
- High‑security perimeters and windy locations where swing gates would be stressed.
Both tracked and cantilever sliding gates can be combined with GSM controllers, intercoms, keypads, and remote fobs, and can be manufactured in steel, aluminium, timber, welded mesh, vertical bar, ornamental, or acoustic designs.
Bi‑Folding Electric Gates
Bi‑folding gates (often called speed gates) have each leaf split into two panels that fold back on themselves, dramatically reducing the space needed and increasing opening speed. They are ideal where fast access and tight space control are critical.
How Bi‑Folding Gates Work
Heavy-duty hydraulic rams or electromechanical drives fold the leaves inward, enabling opening speeds up to around 1 metre per second. Their trackless or minimal-track designs reduce height restrictions and simplify installation across roadways.
Bi‑folding gates are commonly specified with:
- Vertical bar, security mesh, or sheeted infills (and customised finishes).
- Optional PAS 68 crash ratings for vehicle impact resistance at high‑security sites.
- Integrated photocells, obstacle detection, emergency stop, and full compliance with machinery and safety directives.
Best Applications
Bi‑folding gates are particularly suited to:
- Fire stations and ambulance depots (rapid response needed).
- Hospitals and emergency entrances.
- Data centres, utilities, and high‑security commercial sites.
- Busy commercial driveways with continuous in‑out traffic.
They also work for premium residential properties with limited front space where very fast opening is valued, but additional safety measures are essential due to increased entrapment points.
Vertical Lift and Vertical Pivot Gates
Vertical lift and vertical pivot systems move the gate upward instead of sideways, solving problems where lateral space is extremely restricted.
Vertical Lift Gates
Vertical lift gates raise the gate panel straight up using towers and counterweights or chain drive mechanisms. Vehicles and pedestrians pass underneath the gate rather than through a swinging or sliding plane.
These are ideal where:
- Fences are high, but horizontal space is tight.
- The terrain is uneven and there is no reliable runback for sliding gates.
- A compact footprint and clear drive width are required.
They are quick, reliable, and often used in secure industrial or commercial facilities, though they are usually among the more expensive gate options due to the structural requirements.
Vertical Pivot Gates
Vertical pivot gates rotate around a pivot near one side, lifting the gate leaf upward like a barrier while occupying minimal ground space.
Typical advantages include:
- Minimal horizontal clearance required at the driveway.
- Rapid vertical movement, suitable for emergency facilities and car parks.
- Effective operation in snow, ice, or uneven ground conditions.
These systems are constructed from steel or aluminium with vertical bars or solid panels, offering high strength and good resistance to forced entry, and they integrate standard access control and safety systems.
Barrier Arm (Rising Arm) Gates
Barrier arm gates are rising arms that regulate vehicle access but do not prevent pedestrians, so they focus more on traffic control than perimeter denial. They are common in:
- Car parks and multi‑storey garages.
- Toll booths and private roads.
- Airports and rail crossings.
Barrier arms pivot upward 90 degrees, opening in as little as just over one second in some models, making them ideal for handling high volumes of vehicles. They are often combined with ticket machines, ANPR (license plate recognition), keypads, or RFID systems for controlled access.
Electric Gate Operators and Power Options
Electric gate systems rely on two main operator families, each suited to different gate types, usage frequency, and security needs.
Electromechanical Operators
- Operate at 24 V or 120 V
- Use screw drives or gears for movement
- Typically include integrated battery backups
- Ideal for residential gates and light commercial use
- Provide smooth, quiet operation for moderate-duty cycles
Hydraulic Operators
- Operate at 120 V or 240 V
- Deliver higher power and durability for heavy gates
- Handle frequent operation and high-security requirements
- Suitable for industrial, commercial, and high-traffic entrances
- Provide robust performance in extreme conditions
Power Source Options
- Mains electricity: preferred for busy commercial installations
- Solar power: ideal for low-duty gates opening a few times per day
- Battery backup systems: maintain operation during outages
- Can lock gate open or allow limited opening/closing cycles
Special Considerations
- Wooden, close-boarded gates: recommended to use 230 V systems to resist wind load
- Lightweight metal gates: can use lower-voltage kits efficiently
- Ensure operator and power selection matches gate size, material, and usage frequency
Safety, Sensors, and Control Systems
Safety is central to all electric gate systems because poorly designed installations can cause entrapment, crushing, or impact injuries.
Core Safety Components
- Safety edges: pressure-sensitive strips on leading, trailing, and bottom edges that stop or reverse motion on contact where there is any risk of entrapment.
- Photocells: paired infrared beams placed across the opening and around the gate path that stop the gate if the beam is broken by a person, animal, or vehicle.
- Vehicle detection loops:
- Entry loop (outside the gate) to trigger opening.
- Exit loop (inside) to allow vehicles to leave.
- Safety loop near the gate to prevent closing on a stationary vehicle.
- Infrared and microwave sensors: detect movement or presence within the gate area as a backup to loops and edges.
- Warning devices: flashing lights and audible alarms that signal gate movement or imminent operation.
Correct placement of safety edges and photocells differs for swing and sliding systems, and shear points or narrow gaps under 500 mm must be specifically protected. A professional risk assessment is essential for every site, and DIY installation is strongly discouraged for safety reasons.
Access-Control and Smart Features
Modern electric gates support a wide range of control options:
- Keypads and PIN codes.
- Radio fobs and remote controls.
- Proximity cards, RFID tags, and Bluetooth credentials.
- GSM controllers and smartphone apps for remote opening and video intercom.
- Telephone entry systems with integrated cameras and time‑restricted codes.
Commercial systems often integrate with site alarms, CCTV, and wider access‑control platforms, with CAT‑6 or fibre optic cabling run to the gate area for connectivity.
Materials and Applications: Home vs Commercial
Electric gate systems are versatile and can be designed for homes, mixed‑use sites, and heavy‑duty commercial or industrial applications.
Common gate materials include:
- Steel: high strength and impact resistance, ideal for commercial and high‑security sites; requires galvanising or powder coating to resist corrosion.
- Aluminium: lightweight, corrosion‑resistant, ideal for bi‑folding and sliding systems and coastal or damp environments; lower impact resistance than steel.
- Timber / composite: traditional, warm aesthetics for residential and rural sites; needs regular maintenance.
- Wrought iron: highly decorative and prestigious but heavy and more maintenance‑intensive.
Both domestic and commercial users in areas such as Wood Green and across the UK can choose from swing, sliding, and bi‑folding electric gates with different infills and operating systems, tailored to site layout and security requirements.
