Understanding the Difference
Swing barriers (speed gates) use retractable arms or panels — typically glass or acrylic — that swing open when a valid credential is presented and close after passage. They provide a wide, welcoming passage channel and are associated with premium corporate environments. Turnstiles use rotating arms (full-height or waist-height) to allow one-person-at-a-time passage, providing higher security with complete physical separation between controlled and uncontrolled zones.
Throughput Comparison
| System Type | Throughput (persons/min) | Notes |
|---|---|---|
| Swing barrier (standard) | 25–35 | High throughput, smooth flow |
| Swing barrier (high-speed) | 35–50 | Premium products; fast-acting arms |
| Tripod turnstile | 15–25 | Sequential passage; lower throughput |
| Full-height turnstile | 8–15 | Maximum security; slowest flow |
| Optical gate (no barrier) | 40–60 | Highest throughput; lowest physical security |
Security Level
Swing barriers deter tailgating through physical barrier arms and anti-tailgate detection (infrared curtain or camera-based). They are designed to control the honest majority and create accountability — not to stop a determined intruder. For high-security environments, combine with security staffing or CCTV monitoring.
Full-height turnstiles provide the highest physical security — effectively a rotating security cage preventing both climbing and tailgating. Used in prisons, military installations, and high-risk industrial sites. Not appropriate for general office or retail use due to imposing appearance and low throughput.
Accessibility and Equality Act Compliance
The Equality Act 2010 requires reasonable adjustments for disabled persons. Implications for access control:
- Turnstiles: Tripod turnstiles are inaccessible to wheelchair users and those with mobility aids. A wide lane bypass gate is mandatory wherever tripod turnstiles are the primary access route
- Swing barriers: Wide-lane versions (900mm+ clear passage) can accommodate most wheelchair users
- Full-height turnstiles: Not accessible — bypass gate always required
BS 8300 (Design of an accessible and inclusive built environment) provides detailed technical guidance on accessible entrance system design.
Aesthetics and Environment
Corporate offices and prestige environments: Swing barriers with glass or clear acrylic arms, brushed stainless steel bodies, and integrated LED lighting create a welcoming premium aesthetic suited to modern reception areas. Industrial and high-security: Tripod or full-height turnstiles in powder-coated steel reflect the functional, robust character of industrial environments and convey security seriousness. Leisure and entertainment: Stadium and sports venue turnstiles are typically heavy-duty waist-height units designed for burst-throughput at match start and end.
Total Cost of Ownership
| Factor | Swing Barrier | Turnstile |
|---|---|---|
| Capital cost per lane | £3,000–15,000+ | £800–3,500 (waist); £3,000–8,000 (full-height) |
| Maintenance frequency | 6-monthly recommended | Annual typically sufficient |
| Mechanical durability | Good (glass arms designed to break away) | Very good (simple mechanics) |
| Service life | 10–20 years | 15–25 years |
Choosing the Right System
- High-throughput, premium aesthetic: Swing barrier
- Moderate security, cost-sensitive: Waist-height turnstile with bypass gate
- Maximum security, low throughput acceptable: Full-height turnstile
- Accessible public space, high throughput: Wide-lane swing barrier with DDA-compliant lane design
Conclusion
Neither system is universally superior — the right choice depends on throughput, security, aesthetics, and accessibility requirements specific to your project. Browse our pedestrian barrier and access control range.
