Zhonglian Aluminum - Precision you can trust, purity you can verify.
Clean room aluminum profiles are specialized aluminum extrusions engineered for use in controlled environments (clean rooms)-spaces where air particle count, temperature, humidity, and contamination are strictly regulated. Unlike standard aluminum profiles, they are designed to minimize particle generation, resist corrosion, and meet strict industry standards for purity, making them suitable for sensitive manufacturing and research settings.

Products features
| Feature Category | Specific Traits | Purpose |
|---|---|---|
| Contamination Control | - Ultra-smooth surfaces (Ra ≤ 0.8μm, often down to Ra 0.02μm) - No sharp edges, crevices, or porous structures - Low particle emission (<10 particles/ft³ for 0.5μm+ particles) |
Prevent dust accumulation/trapping; avoid releasing particles that disrupt clean room air quality. |
| Material & Durability | - High-purity aluminum alloys (e.g., 6061-T6, 6063-T5, ≥99.5% Al content) - Corrosion resistance (500+ hours salt spray test per ASTM B117) - Temperature stability (-40°C to +120°C continuous use) |
Withstand harsh cleaning chemicals, humidity, and temperature fluctuations; avoid alloy degradation that could release impurities. |
| Precision & Compatibility | - Tight extrusion tolerances (±0.05mm on critical dimensions) - CNC-machined finishes (drilling, tapping, deburring) for seamless installation - Customizable cross-sections (via dedicated tooling) |
Ensure perfect fitting (no gaps for contaminants); adapt to unique clean room structure designs (e.g., frames, partitions). |
| Compliance & Traceability | - Certifications (CE, TUV, SGS, RoHS, ISO 9001) - Full batch traceability (raw material to finished product) - Particle emission and surface purity testing |
Meet global industry regulations (e.g., pharmaceutical, semiconductor) and simplify audit processes. |
Products Applications
Clean room aluminum profiles are used in environments where contamination control is non-negotiable. Common use cases include:
✅ Pharmaceutical & Medical:
Frames for clean room partitions, drug manufacturing equipment enclosures, and sterile packaging lines (compliant with FDA/EMA standards).
✅ Semiconductor & Electronics:
Structural components for wafer fabrication facilities (ISO 1–ISO 3), PCB assembly lines, and ESD (electrostatic discharge)-protected zones.
✅ Biotech & Life Sciences:
Enclosures for lab equipment (e.g., biosafety cabinets), cell culture rooms, and vaccine production facilities.
✅ Aerospace & Optics:
Frames for precision optics manufacturing, satellite component assembly, and aerospace part testing (where micro-contaminants risk product failure).
✅ Food Processing:
Structures for food-grade clean rooms (e.g., beverage bottling, high-purity ingredient handling) to meet hygiene standards (e.g., FDA, EU 10/2011).
