Shenzhen Experimental High School Park is a key construction project of the Shenzhen municipal government, operating as a fully residential public school directly under the municipal administration. The total investment in school construction exceeds 2 billion yuan, covering an area of approximately 202,000 square meters. It includes four public high schools with a total scale of 186 classes, providing 9,300 public high school places.
Fire-rated doors in Shenzhen Experimental High School technology overview,
① Application Areas & Positioning
Fire-rated doors are strategically deployed across Shenzhen Experimental High School to compartmentalize fire hazards and ensure safe evacuation:
Stairwells & Evacuation Routes: Installed in pressurized staircases and escape corridors (e.g., high school dormitory stairwells), typically using Class-B fire doors
(≥1-hour fire resistance) to maintain smoke-free egress paths during emergencies. Laboratories & High-Risk Zones: Chemistry/biology labs equipped with Class-A fire doors (≥1.5-hour rating) to isolate flammable materials and prevent fire
spread to adjacent classrooms.
Library & Archives: Segregating book repositories with Class-A fire doors to protect irreplaceable assets.
Dormitory Corridors: Partitioning residential zones to limit horizontal smoke diffusion, especially at floor junctions.
Mechanical/Electrical Rooms: Securing HVAC and electrical vaults with steel-core fire doors to prevent utility-induced fires from propagating.
② Core Functions
Fire/Smoke Compartmentalization: Confine flames and toxic gases within the origin zone (60–120 min integrity per GB 12955-2008).
Egress Assurance: Maintain unobstructed evacuation routes to refuge areas, critical during drills or actual emergencies.
Structural Integrity Protection: Shield load-bearing walls and staircases from heat-induced collapse.
Daily Safety Compliance: Balance fire safety with accessibility using intelligent door systems (e.g., electromagnetic holds for peak-hour traffic).
③ Product Specifications & Features
Material & Structural Design
Steel-Core Construction:
Galvanized steel frames (1.2–1.5mm thickness) with rock wool/mineral wool insulation for high durability in humid climates.
Coastal Corrosion Resistance: Powder-coated finishes to withstand Shenzhen's high humidity.
④ Certifications & Performance
Compliant with GB 12955-2008 (Class A/B) and ISO 17941:2015 for hinges and hardware.
Height Limitation: ≤2,300mm to ensure operational stability and compliance with school safety codes.
⑤ Intelligent Components
Auto-Closing Mechanisms: Electromagnetic hold-open devices linked to fire alarms; close within ≤30 seconds post-alert.
Sealing Systems: Triple-lip intumescent gaskets (expand at 200°C+) and smoke seals (gap tolerance ≤3mm).
