2025-07-30

I. Core System Components

1.1 Door Structure Design

Door Frame System: Constructed with 60*30mm stainless steel 304 square tubes, electropolished surface (Ra≤0.4μm)

Door Leaf Construction:

Panel: 1.2mm thick stainless steel (mirror finish)
Core Material: 50mm thick aluminum honeycomb core (density 8kg/m³)
Sealing Edge: Fully wrapped EPDM gasket (Shore hardness 65±5)

1.2 Observation Window Configuration

Area Type	Window Configuration	Special Requirements
Clean Corridor	Double-glazed tempered glass (6+12A+6)	With electric defogging function
Changing Room	No observation window design	Enhanced privacy protection
Material Transfer	Operable observation window	Pneumatic sealing device

II. Key Functional Components (Revised Content)
