This premium cleanroom door concept is aimed at engineering clients and project owners who value industrial aesthetics, flush surfaces and clear structural logic. The door is designed as part of the cleanroom envelope, not just an accessory, with attention to bending stiffness, sealing lines and visual brand consistency.
Built for ISO and GMP environments where quality, craft and brand image must align with technical performance.
| Door Type | Flush swing cleanroom door, single or double leaf |
|---|---|
| Leaf Material | Stainless steel (304/316) or GMP-grade HPL skins |
| Core Construction | Honeycomb or mineral core with reinforced perimeter frame for stiffness |
| Frame Material | Stainless steel or powder-coated steel, flush-mounted to wall system |
| Surface Finish | Brushed or coated industrial finish, easy-clean and low glare |
| Cleanroom Class | Suitable for ISO Class 5–8 depending on configuration |
| Sealing System | Continuous perimeter gasket with calibrated compression and low leakage |
| Vision Panels | Optional flush glazing with sealed frames, rectangular or circular |
| Hardware | Heavy-duty hinges, cleanroom handles, concealed or surface closers |
| Typical Sizes | Project-based sizing, commonly 900–1200 mm width, 2100–2400 mm height |
The door leaf is built as a composite element. A perimeter frame carries hinge loads and provides bending stiffness, while internal reinforcement and a honeycomb or mineral core control deflection and help achieve a flat surface. Stainless steel or HPL skins are bonded to this core, giving a smooth, industrial finish with no exposed fasteners.
Edge details are welded or formed to avoid gaps and ledges. Corners are controlled for tight radii, and joints between leaf, frame and vision panels are designed so that cleaning tools can reach every area without visual interruption.
Frames are dimensioned to sit flush with cleanroom wall panels or carefully prepared masonry, maintaining a continuous industrial line around the opening. Anchors are arranged to balance structural loads with minimal disturbance to wall surfaces, and interfaces are sealed to keep leakage low and surfaces smooth.
High-visibility corridors and airlocks in flagship GMP production lines, where the door appearance must match the plant’s industrial brand image.
Main corridors and viewing zones in electronics or semiconductor plants, combining flush doors with glass panels and clean wall systems.
Demonstration laboratories, pilot plants and visitor tour routes, where internal technical quality is part of the site’s visual story.
The combination of flush construction, reinforced core, industrial-grade hardware and refined finishes makes it suitable for high-profile industrial projects.
Yes. Design choices follow ISO 14644 guidance for air cleanliness and GMP expectations for smooth, easy-clean surfaces and sealed frames.
By using a perimeter frame, internal reinforcement and tested core materials, we limit deflection under pressure and maintain long-term flatness.
Surface finishes and hardware appearance can be customised to align with brand or architectural guidelines while retaining cleanroom performance.
A continuous perimeter gasket with calibrated compression is complemented by precise leaf and frame interfaces to keep leakage low.
Frames are designed to sit flush with cleanroom panels or prepared masonry openings, using anchors and sealants suitable for clean surfaces.
Options include heavy-duty or concealed hinges, closers, stainless handles and locking sets that match industrial aesthetics.
Material and finish selection takes into account common disinfectants, aiming for corrosion and stain resistance over repeated cleaning cycles.
Yes. Flush, sealed glazing is used to keep panels aligned with the leaf surface and avoid contamination traps.
We provide drawings, specifications, sealing details, installation guides and maintenance recommendations for project and validation work.
