Shenzhen R&F Dream Center is one of its representative commercial complex projects, which opened on December 24, 2022, with a total construction area of 100,000 square meters. The project is positioned as an ecological-themed commerce, connecting with municipal parks through scenes such as the Ecological Green Valley and Vibrant Streets, and seamlessly integrating with Metro Line 16. During the Spring Festival of 2023, the self-operated cinema 'R&F Dream Gallery' within the project saw a 100% occupancy rate for some VIP screening rooms.
Fire-rated doors in Shenzhen R&F Dream Commercial Complex technology overview,
① Positioning and Application Zones
Vertical Evacuation Paths:
Pressurized stairwells linking retail floors (e.g., Levels B1–L5), fitted with Class-B fire doors (≥60-min rating) to maintain smoke-free escape routes.
Elevator lobbies and firefighter access shafts secured with Class-A steel doors (≥90-min rating).
High-Risk Technical Zones:
Electrical substations, HVAC plants, and generator rooms isolated by blast-resistant doors (multi-layer steel/aramid composites).
Commercial kitchen entrances (e.g., food courts) using stainless steel doors with corrosion-resistant seals.
Public Assembly Areas:
Cinema multiplex corridors and atrium junctions equipped with glazed fire doors (ceramic glass panels) for visibility without compromising 60-min integrity.
Service & Logistics Zones:
Loading docks and garbage chute access points protected by industrial-grade fire doors (impact-resistant cores).
② Critical Functions
Fire/Smoke Containment:
Intumescent seals expand at 200°C+ to seal gaps ≤3mm, confining flames/toxic gases within origin zones (60–120 min integrity per GB 12955-2008).
Egress Optimization:
Electromagnetic hold-open devices release within ≤30 sec upon BMS signal, enabling compliance with GB 50016-2014 crowd-flow protocols.
Integrated illuminated boundary markers (e.g., HH-DT-210230) auto-activate during power failures to guide evacuation.
Structural Resilience:
Reinforced hinges (4+ bearings) withstand seismic loads and stack-effect pressures in high-rise towers.
③ Product Specifications and Features
Core Construction: Galvanized steel frames (1.5mm thickness) with rock wool/mineral wool insulation for humid subtropical environments.
Glazed Variants: Ceramic-fired glass (6mm + 12A air gap + 6mm tempered glass) achieving 60-min integrity and 45% light transmission.
Specialized Types: Stainless steel doors (304-grade) for kitchens; blast-resistant Whipple structures for utility zones.
④ Intelligent Systems
Auto-Closing Mechanisms: Hydraulic closers for single doors; sequential closers + flush bolts for doubles.
IoT Monitoring: Real-time status (open/closed/temperature) fed to BMS via pre-installed sensors.
⑤ Certifications & Performance
Compliant with GB 12955-2008 Class A/B and ISO 17941:2015 for corrosion/wind resistance.
Acoustic Rating: STC 40+ for noise reduction in cinema and office zones.
Sustainability: Recycled steel cores + low-VOC sealants (LEED/China Green Star aligned).
