Soaring at 356 meters and certified by CTBUH as "China's Tallest Equal-Height Twin Towers" Shenzhen Star River Twin Towers redefine urban skylines while pioneering safety innovations. As first Chinese skyscraper to achieve dual WELL Platinum + LEED Gold sustainability certifications, it integrates cutting-edge fire safety systems, particularly advanced fireproof doors—to protect its 30,000 occupants and 916+ enterprises, including semiconductor leaders like Shanghai Bright Power semiconductor.Shenzhen Galaxy Twin Towers are two skyscrapers located at No. 8 Yaxing Road, Bantian Street, Longgang District, Shenzhen, Guangdong Province, China. The east and west towers are of equal height, with a building height of 369 meters. The total construction area is approximately 360,000 square meters, featuring 73 floors above ground and 5 underground. The towers were structurally topped out in December 2021 and put into use on March 31, 2023. After the completion of the Star River Twin Towers, the park area will ultimately form five major sectors including the Twin Towers, International Art Center, Business Plaza, Ecological Building and IEO Headquarters Cluster, showcasing the charm of the mountain-water CBD on the undulating terrain that rises in the southeast and descends in the northwest.
Fire-Rated Doors in Shenzhen Galaxy Twin Towers technical overview,
① Application Areas & Positioning
Fire-rated doors are strategically installed in critical zones to compartmentalize fire/smoke and ensure safe egress:
Stairwells/Emergency Exits: All access points to pressurized staircases (e.g., core evacuation routes).
Elevator Lobbies: Entrances to elevator banks and high-rise lift halls.
Mechanical/Electrical Rooms: Server rooms, transformer vaults, and HVAC zones.
Floor Segregation: Between tenant spaces, corridors, and atria (creating fire compartments every 5–10 floors).
Basements & Parking: Access to utility tunnels and vehicle storage levels.
Refuge Floors: Temporary safe-haven areas (every 15–20 floors).
② Core Functions
Compartmentalization: Confine fire/smoke within origin zones (60–240 mins rating).
Egress Protection: Maintain exit paths clear of smoke/toxic gases.
Structural Integrity: Prevent collapse of critical escape routes.
Thermal Insulation: Limit radiant heat transfer to adjacent areas.
Pressurization Support: Integrate with mechanical smoke control systems.
③ Product Specifications & Features
Material Composition:
Steel Core: 1.2–1.5mm galvanized steel sheets with mineral-infused insulation.
Glazed Variants: Ceramic-fired glass (60–120 mins rating) with intumescent seals.
④ Intelligent Systems
Self-Closing Mechanisms: Electromagnetic hold-open devices linked to fire alarms.
Acoustic Seals: Intumescent strips expanding at 200°C+ to seal gaps.
Smoke Seals: Triple-lip gaskets (≤3mm gap tolerance).
⑤ Certifications
China GB Standards: GB 12955-2008 (Class A: ≥90 mins).
International: UL 10C (US), EN 1634-1 (EU), and NFPA 80/101 compliance.
