Clean room door panels combine a rigid Polyurethane (PUR) or Polyisocyanurate (PIR) foam core with metal cladding — typically stainless steel or pre-painted galvanized steel finished with an antibacterial coating. The closed-cell core delivers effective insulation and moisture resistance while allowing the door leaf to sit flush with the surrounding wall system.
Tongue-and-groove interlocking joints with internal cam-lock mechanisms create airtight seals and thermal bridge-free construction. Standard thicknesses range from 50-200mm, with common door dimensions of 700x1700mm or 800x1800mm. The modular design enables vertical or horizontal installation without on-site cutting.
These panels serve pharmaceutical facilities, food processing plants, laboratories, and biotechnology environments where hygiene and temperature control are critical. The closed-cell foam structure inhibits fungi and bacteria growth while maintaining consistent internal conditions and minimizing energy consumption.
Operational features include manual or automated operation compatibility, self-rising hinges, and sweep-type sill gaskets. Customization options encompass tailored dimensions, RAL color selections, Polyvinylidene Fluoride (PVDF) finishes, viewing windows, and specialized hardware to meet specific project requirements while maintaining compliance with EC/USDA and FDA standards.
Trusted Worldwide Clean Room Door Panel Wholesaler
A cleanroom is only as tight as its doors. RaxPanel manufactures cleanroom door panels engineered to sit perfectly flush with the surrounding wall panels on both sides, preserving the smooth, contamination-controlled enclosure that GMP and ISO 14644 facilities demand.
Every door panel pairs a rigid PUR/PIR core with stainless steel or pre-painted steel cladding, machined to match the exact wall thickness so that no step or recess interrupts the surface. Flush-mounted hardware, concealed hinges, and drop-down sweep gaskets maintain an airtight seal under positive or negative room pressure, preventing unfiltered air exchange when the door is closed. Optional interlocks, automatic operators, and double-glazed viewing windows integrate with access-control and airlock sequencing.
We produce manual and automated cleanroom doors in standard and custom sizes, with PVDF or HDP coatings that resist daily sterilization. Whether you need a single personnel door or a full airlock suite, tell us your pressure cascade, traffic level, and clear opening, and we will engineer the door to fit.

ISO 14644 & GMP Clean Room Panel System Guide
Cleanroom sandwich panels are specifically engineered for contamination-controlled environments in pharmaceutical manufacturing, semiconductor fabrication, biotechnology labs, and medical operating suites. Built with anti-static, anti-bacterial coated steel facings or Grade 304 stainless steel bonded to Rockwool or Aluminum Honeycomb cores, these panels comply with ISO 14644-4 Class 1 to Class 9 and EU GMP Annex 1 sterility mandates.
💡 Pro Tip: Flush Joint Aluminum Profiles & VHP Resistance
At RaxPanel, our cleanroom panels feature double-male-female aluminum keels that interlock completely flush with 0mm surface steps. Joints are sealed with medical-grade non-outgassing silicone, eliminating ledges where dust or microbes collect and standing up to daily Vaporized Hydrogen Peroxide (VHP) sterilization.

1. Why Are Anti-Static (ESD) and Anti-Bacterial Coatings Required?
Standard building steel paint attracts airborne dust through static charge. RaxPanel cleanroom coatings maintain surface resistivity of 10⁶ to 10⁹ Ω/sq to prevent Electrostatic Discharge (ESD) damage in microelectronics, while nano-copper/silver ion additives inhibit bacterial growth by > 99.9%.
2. What Core Options Fit Cleanroom Walls vs Walk-On Ceilings?
Cleanroom core selection governs structural deflection under differential air pressure (+50 Pa) and foot-traffic maintenance loads:
3. How Integrated Cleanroom Doors and Double-Glazed Windows Maintain Air Pressure
RaxPanel cleanroom doors install completely flush with adjacent wall panels on both sides. Windows feature double-glazed toughened safety glass filled with dry nitrogen gas and internal desiccant to prevent condensation fogging.
4. Chemical Washdown Immunity (VHP & 70% IPA)
🧪 Sterilization Chemical Resistance:
- Vaporized Hydrogen Peroxide (VHP): Special HDP/PVDF paint coatings withstand 35% concentration VHP decontamination cycles without surface blistering.
- Alcohol & Disinfectant Wipes: Resistant to continuous wiping with 70% Isopropyl Alcohol (IPA), sodium hypochlorite, and quaternary ammonium biocides.
5. Where Are Cleanroom Panel Systems Most Commonly Installed?
💊 Pharmaceutical Facilities & Sterile Filling Rooms
EU GMP Grade A/B/C/D compliant aseptic processing and packaging suites.
🔬 Semiconductor & Optoelectronics Fabs
ISO 5 / Class 100 anti-static ESD safe wafer fabrication and laser labs.
6. Aluminum Radius Coving for 90° Wall-to-Floor Junctions
To comply with GMP sanitation, all 90° internal wall-to-wall and wall-to-floor corners are fitted with clip-in concave aluminum coving profiles (R50mm), ensuring rounded, easy-to-wipe corner transitions.
Frequently Asked Questions (FAQS)
1. What ISO cleanroom classifications do RaxPanel cleanroom panels satisfy?
Our cleanroom panel systems comply with ISO 14644-4 Class 1 through Class 9 specifications, as well as EU GMP Annex 1 Grade A, B, C, and D aseptic manufacturing standards.
2. Why is a flush-joint system mandatory for pharmaceutical cleanrooms?
Flush joints eliminate steps, gaps, and exposed screw heads where dust, bacteria, or spores can hide, allowing thorough wiping and biocide disinfection.
3. What core material is recommended for walk-on cleanroom ceiling systems?
Aluminum Honeycomb core is recommended for walk-on ceilings due to its high stiffness-to-weight ratio, structural flatness, and support for HVAC maintenance personnel.
4. Are RaxPanel cleanroom coatings resistant to Vaporized Hydrogen Peroxide (VHP)?
Yes. Our specialized PVDF and HDP cleanroom steel coatings withstand continuous 35% VHP vapor decontamination cycles without paint peeling or discoloration.
5. How do anti-static ESD cleanroom panels work?
ESD coatings maintain a surface resistivity of 10⁶ to 10⁹ Ω/sq, safely bleeding off static charges to ground and preventing micro-particle static attraction.
6. Are cleanroom doors and windows pre-engineered to fit the panel thickness?
Yes. RaxPanel cleanroom doors and double-glazed nitrogen-filled windows are manufactured to match the exact panel thickness (50mm / 75mm / 100mm) for double-sided flush installation.
7. What aluminum profile accessories are supplied with cleanroom panel packages?
Packages include aluminum floor channels, internal concave corner covings, external 3-way corner caps, ceiling suspension T-bars, and medical silicone sealants.
