Fire-Rated Cleanroom Steel Doors | Chemical-Resistant, Low-Profile Design | CE & UL-Certified

Engineered for high-traffic controlled environments requiring enhanced visibility and robust sealing. Certified for ISO 14644-1 compliance in pharmaceutical, aerospace, and precision manufacturing facilities.

Product Features

Premium Aesthetic & Functional Design

• Matte blue painted cold-rolled steel offers scratch-resistant surfaces (Ra ≤0.6μm) with embedded desiccant to prevent internal condensation.

• Quad tempered glass panels provide 360° visibility while maintaining structural rigidity, ideal for multi-zone monitoring.

• Full-perimeter sealant strips ensure uniform compression, achieving <0.08 Pa leakage rates (EN 12207 Class 4 certified).

Industrial-Grade Security & Durability

• Six reinforced hinges distribute 300kg load capacity, enabling 200,000+ cycles without sagging (tested per ANSI/BHMA A156.2).

• Anti-tamper lock system features dual-latch engagement, compatible with RFID/badge access integration.

• Oversized dimensions support high-volume logistics workflows while meeting ergonomic clearance standards.

Contamination Control

• Non-reflective matte finish reduces glare-induced particulate detection errors in optical labs.

• Sealant strips resist deformation under ±15°C thermal fluctuations, critical for cold storage or autoclave-adjacent zones.

Application Scenarios

Aerospace Composite Cleanrooms

• Maintains ISO Class 7 conditions during carbon fiber layup, with quad-window visibility for QC oversight.

Pharmaceutical Lyophilization Suites

• Withstands -40°C freeze-drying cycles while preventing moisture ingress (per USP <797> guidelines).

Automotive Battery Manufacturing

• ESD-safe matte surface (10^6–10^9 Ω/sq) prevents static discharge in lithium-ion cell assembly areas.

Hospital Sterile Processing Departments

• Full-perimeter seals block bioaerosols during instrument transfer (AAMI ST79:2017 compliant).

FAQs :

1. How does the quad-pane observation window improve operational efficiency?
The four-panel design allows multi-angle monitoring of cleanroom workflows without door opening, reducing air exchange disruptions by up to 40% compared to single-window designs.

2. Can the matte blue finish withstand abrasive cleaning in sterile environments?
Yes, the coating utilizes nano-ceramic additives (ASTM D4060 Level 4 hardness), resisting 10,000+ wipe-down cycles with isopropyl alcohol or hydrogen peroxide solutions.

3. Are the hinges pre-adjusted for heavy bi-fold PPE doors?
The six hinges include pre-installed nylon washers and grease ports, enabling smooth operation of 120kg PPE transfer systems common in vaccine production facilities.
