Medical stainless steel door product description
Structure and process
The door body base material is 1.2mm thick 304 stainless steel or galvanized electrolytic steel plate (tensile strength ≥500MPa), and the interior is filled with 120kg/m³ high-density fireproof rock wool (fire resistance temperature ≥1100℃). The door body is integrated through laser seamless welding technology, and the surface is covered with nano-level antibacterial powder coating (in accordance with ISO 22196 standard, antibacterial rate ＞99.9%), and the overall thickness is precisely controlled at 50mm±2mm. The seamless design completely eliminates sanitary dead corners and can withstand high-frequency scrubbing of highly corrosive disinfectants such as sodium hypochlorite every day.
Double safety certification protection
Fireproof performance: passed GB 12955-2015 Class A fireproof certification, fire resistance limit ≥1.5 hours, back-fire surface temperature rise <140℃;
Impact resistance: static compressive strength of door body ≥800N, hinge load-bearing capacity of 200kg (3 times higher than national standard), can withstand high-speed impact of hospital beds and medical equipment without deformation.
Medical-grade dynamic sealing system
The door frame integrates a three-layer sealing structure: EPDM airtight strips to achieve basic sealing, magnetic adsorption strips to enhance closing tightness, and the bottom automatic lifting baffle (sealing force>40N) forms physical isolation at the moment of closing the door;
Sound insulation performance>28dB (in line with GB/T 8485 standard), airtightness reaches ISO Class 8 cleanliness level (air leakage ≤0.02m³/h·m).
Intelligent medical ecological integration
Supports non-contact induction opening and closing (sensing distance 0-30cm adjustable), hospital access control system linkage, and automatic release of safe passages when power is off;
Hydraulic door closer opening and closing speed is adjustable in 4 gears (90° opening takes 3-8 seconds), and automatically rebounds within 0.3 seconds to prevent pinching when encountering obstacles.
Key technical parameters
Door opening adaptation range: width 800-2000mm, height 2100-2400mm (according to GB/T 5824-2021 standard, support non-standard customization);
Surface physical properties: coating hardness ≥ 2H (pencil hardness test GB/T 6739-2006), scratch resistance is 3 times higher than ordinary medical doors;
Mechanical durability: passed 150,000 fatigue opening and closing tests (QB/T 3893-1999), equivalent to 10 years of high-frequency use in hospitals;
Radiation protection options: observation window lead equivalent 0.5-2.0mmpb (meet GBZ 130-2020 radiation protection requirements).
Special adaptation for medical scenarios
Operating room/ICU: airtight structure maintains positive pressure environment and blocks the transmission chain of microorganisms;
Negative pressure isolation ward: dynamic sealing system stably maintains ≥5Pa pressure difference (in line with WHO isolation standards) to prevent the spread of pathogens;
Biological laboratory/hazardous chemical pharmacy: explosion-proof multi-point locks + acid and alkali resistant coating, adapted to strong corrosion environment;
Public medical channel: 1.2mm thickened stainless steel anti-collision guard plate, to resist 200+ impacts of bed pushers per day.
Certification and service system
The product has passed the YY/T 0627-2023 medical door industry standard and EU CE-MDR medical device directive certification, and provides triple test reports for fire resistance, air tightness, and radiation protection. The main structure has a 10-year warranty, supports BIM modeling pre-installation and smart hospital system integration, and provides a full life cycle safety management solution for medical buildings.
