Selecting the correct revolving door diameter is critical for ensuring adequate traffic capacity and proper integration with the building architecture. This guide covers standard size ranges and selection criteria for different application types.
1. Diameter and Passage Width Relationship
The clear passage width between wings and enclosure wall determines usable door opening area. For three-wing doors, passage width equals approximately one-third of the total diameter minus enclosure wall thickness. A 3.0-meter diameter three-wing door provides approximately 900mm passage width. Four-wing doors of equivalent diameter provide slightly narrower individual passage widths due to four wings sharing the circumference, but continuous flow capacity is higher due to more compartments.
2. Standard Diameter Ranges
Two-wing automatic revolving doors typically range from 2.0 to 2.6 meters in diameter. Three-wing doors are available from 2.4 to 3.6 meters. Four-wing heritage doors range from 3.0 to 4.2 meters. Most commercial buildings use 2.8-3.0 meter three-wing doors as a standard specification providing balanced cost, capacity, and space requirements. Luxury hotels and high-end office buildings typically specify 3.3-3.6 meter four-wing doors for maximum comfort and prestigious appearance.
3. Height Requirements
Standard revolving door enclosure heights range from 2.1 meters for standard applications to 3.0 meters or higher for premium installations. Higher enclosures improve aesthetic appearance and reduce the tunnel effect experienced by users passing through. Door wing height typically matches enclosure height minus 50-100mm for clearance. Accessibility requirements may dictate minimum clear opening heights for compliance with disability access regulations.
4. Space Planning and Structural Requirements
Revolving door enclosures require adequate structural support to transfer wind loads and impact forces from the enclosure to the building structure. The floor must be capable of supporting the enclosure weight plus dynamic loads during operation. Structural steel reinforcement is typically required for installations on elevated floors or where concentrated loads cannot be distributed to adequate foundation support.
5. Accessibility Compliance
Revolving doors present accessibility challenges for wheelchair users and persons with mobility impairments who cannot safely navigate the rotating door mechanism. Building codes in most jurisdictions require alternative accessible entry points adjacent to revolving doors. Companion wheelchairs are typically not accommodated in standard revolving door configurations, necessitating swing door or sliding door alternatives with adequate width and automatic operation.
