Turnstile, Speed Gate & Boom Gate FAQs

Choosing the right access-control solution depends on your site, security requirements, traffic flow and operating environment. These FAQs answer common questions about Flow Systems turnstiles, speed gates, revolving doors, access-control booths and boom gates, including installation, integration, safety, maintenance and support.

Are turnstiles suitable for indoor and outdoor sites?

Yes. Flow Systems supplies turnstiles for both indoor and outdoor applications, but the right solution depends on the site’s environment and security requirements. For exposed perimeters, mines, factories, warehouses and stadiums, full-height industrial turnstiles with corrosion-resistant finishes are typically the best choice. These are designed for demanding environments where durability and strong access control are essential.

For indoor or prestige entrances, speed gates and waist-height turnstiles are often more suitable, offering a cleaner architectural appearance and smoother pedestrian flow. Waist-height turnstiles are generally used where lower levels of physical security are required.

For outdoor installations, the finish and protection specification are critical. Flow Systems offers stainless steel, powder-coated, hot-dip galvanised, and mild steel options, depending on the project requirements, environment, and exposure conditions.

Should I choose a full-height or waist-height turnstile?

The right choice depends on the level of security and the user experience you want to create. Full-height turnstiles are best suited to high-security perimeter control where preventing tailgating and unauthorised access is a priority. They provide a physical barrier and are commonly used at mines, industrial facilities, warehouses, stadiums, and universities.

Waist-height turnstiles are more appropriate where controlled pedestrian flow is needed without creating a heavily restricted or industrial appearance. They offer a more open and welcoming entrance experience and are commonly used in offices, commercial buildings and reception areas.

Flow Systems offers industrial full-height turnstiles for maximum security, as well as waist-height tripod, 3-arm and 4-arm turnstiles for lower-security environments.

What is the difference between tripod turnstiles and speed gate systems?

Flow Systems offers several turnstile and pedestrian-access solutions for various applications.

Tripod turnstiles are compact, waist-height mechanical barriers commonly used to control pedestrian flow in offices, schools, and transport environments. They are very effective in controlling one person at a time both when entering and exiting. 

Speed gates are premium access-control lanes designed for high-throughput, image-sensitive entrances. They combine fast operation, touchless access, and modern aesthetics, making them ideal for corporate headquarters, commercial buildings, and premium facilities.

What materials, finishes and weatherproofing options are best for outdoor turnstiles?

Outdoor performance depends heavily on the specification selected for the project. Flow Systems offers industrial turnstiles in stainless steel, mild steel, powder-coated and hot-dip galvanised finishes to suit different environmental conditions.

In coastal, dusty, wet, or harsh industrial environments, selecting the correct substrate, protective coating, and electrical protection is essential. Hot-dip galvanised finishes are commonly specified for heavy-duty outdoor applications because they provide strong corrosion resistance.

Prestige turnstile and speed gate systems may also incorporate aluminium, glass, and architectural stainless steel elements for modern entrance environments. When planning an outdoor installation, Flow Systems recommends confirming the exact finish, enclosure rating and environmental specification during the quotation and design stage to ensure long-term durability.

Can Flow Systems turnstiles integrate with RFID, biometrics, QR scanners and other access-control systems?

Yes. Flow Systems turnstiles can integrate with a wide range of access-control technologies, including:

  • RFID and proximity card readers 
  • Facial recognition systems 
  • Fingerprint and biometric readers 
  • Palm and vein recognition systems 
  • QR and ticketing systems 
  • Push-button and remote-control systems. 

Many prestige entrance solutions also include battery backup to maintain operation during power failures or load shedding. Power and networking requirements vary depending on the project and selected access-control equipment. Flow Systems works with clients and integrators to ensure compatibility between the turnstile system and the broader security infrastructure.

How secure are turnstiles, and how many people can they process per minute?

Different turnstile systems balance security and throughput differently. Full-height turnstiles provide the highest level of physical access control and are designed to reduce tailgating and unauthorised entry. Because of their restrictive nature, they generally process fewer people per minute than open-lane systems.

Waist-height turnstiles, flap barriers and speed gates typically allow faster pedestrian throughput while still maintaining controlled access. Actual throughput depends on several factors, including:

  • The type of credential being used 
  • Reader response times 
  • Supervision levels 
  • Lane configuration 
  • User behaviour.

As a general rule, higher-security barriers provide lower free-flow throughput, while prestige and speed-lane systems prioritise faster pedestrian movement.

Do turnstiles comply with emergency egress, fire and accessibility requirements?

They can, provided the overall entrance design complies with local building, fire and accessibility regulations. Turnstiles should not form the only accessible entrance or emergency escape route. In most projects, an adjacent accessible gate, a swing door, or a compliant escape route is required.

Our systems can be configured with fail-safe or emergency-release functionality so that lanes unlock or rotate freely during emergency situations or when a fire alarm is activated. Compliance requirements vary by region, building type and occupancy classification, so final system design should always be reviewed against applicable local regulations and project requirements.

What does installation involve, and does Flow Systems install outside Johannesburg?

Yes. Flow Systems designs, manufactures, installs and throughout South Africa and across selected international regions. Installation is more than simply delivering equipment to the site. A typical project may include:

  • Civil works and plinth preparation  
  • Access-control integration together with the existing or new access control system 
  • Commissioning and testing 

Certain systems require prepared level mounting surfaces, anchor bolts and dedicated power supplies.

Flow Systems has installers and agents across South Africa and has completed projects in countries including Botswana, Mozambique, Zambia, Ghana, Nigeria, Saudi Arabia, the UK, the UAE and the Czech Republic. Lead times, installation schedules, and project costs depend on the specific system, site conditions, and project scope and are therefore provided on a quotation basis.

What maintenance, warranty and support can buyers expect?

Flow Systems offers preventive maintenance, full maintenance contracts, once-off repairs, and equipment rental options, depending on project requirements. Its industrial turnstile range includes long-term warranty support, with selected products carrying warranties of up to 10 years.

Routine maintenance typically includes:

  • Mechanical inspections 
  • Sensor and reader testing 
  • Lubrication and adjustment 
  • Safety checks 
  • Electrical diagnostics 

If a system stops operating correctly, the first checks usually involve:

  • Power supply status 
  • Emergency or fire-alarm inputs 
  • Reader authorisation 
  • Sensor detection zones 
  • Battery backup systems 

Ongoing maintenance helps ensure reliability, safety and long-term system performance.

When is a revolving door a better choice than a turnstile?

A revolving door is often the better solution when the entrance needs to balance security, aesthetics and climate control. Flow Systems supplies manual, automatic and access-controlled revolving doors for premium commercial environments, including corporate offices, public buildings and high-end facilities.

Compared to industrial turnstiles, revolving doors provide:

  • A more refined architectural appearance 
  • Improved pedestrian guidance 
  • Reduced airflow and energy loss 
  • Better climate control inside the building 

For higher-security applications, access-controlled revolving doors can also provide one-person-at-a-time entry management with anti-tailgating functionality.

Are revolving doors safe, accessible, and energy-efficient?

Yes, when correctly designed and installed. Flow Systems revolving doors can incorporate infrared safety sensors and emergency-release functionality to enhance user safety and emergency egress.

For accessibility compliance, revolving doors should be paired with an adjacent compliant entrance door or accessible access route. From an energy-efficiency perspective, revolving doors help reduce unwanted airflow between indoor and outdoor environments. This can assist with temperature control and reduce HVAC energy loss in commercial buildings.

The final configuration should always be reviewed against the applicable accessibility, fire and building-code requirements for the project.

When should I choose a speed gate, access-control booth or boom gate instead of a turnstile?

Different access-control products solve different security and traffic-flow challenges.

Choose a speed gate when:

  • The site requires fast pedestrian throughput 
  • The entrance is image-sensitive or prestige-focused 
  • Touchless access control is preferred

Choose an access-control booth or mantrap when:

  • One-person-at-a-time access is critical 
  • The site requires a higher-security containment solution 
  • Strong anti-tailgating control is needed

Choose a boom gate when:

  • The traffic is vehicular rather than pedestrian 
  • Vehicle access control is required for office parks, industrial facilities, shopping centres, healthcare sites or residential developments
