What it is: A hand-made cleanroom sandwich panel consists of color-coated steel or stainless steel face sheets, galvanized steel frame strips and corner fittings on all four edges, and a reinforced core of rock wool, MgO, PU or honeycomb. It is manufactured through heating, pressing and curing.
Key features
✔ High strength: reinforced frame and corner fittings; confirm allowable loads and support spacing for each assembly
✔ Fire safety: confirm the complete panel assembly, test standard and current report for the project
✔ Flat & airtight: metal faces with male–female joints or center aluminum connections; agree joint sealing and dimensional tolerances
✔ Customizable: catalogue standard width 1,180mm; discuss custom sizes and openings for doors, windows and pass boxes
✔ Material options: PE polyester, PVDF, stainless steel, anti-static faces; rock wool, PU, phenolic, honeycomb cores
Typical specifications: The company catalogue lists a 50mm standard thickness, 1,180mm standard width and cut lengths of 100–6,000mm for hand-made panels. Confirm the current offered configuration in your quotation.
Applications
✔ Pharmaceutical / GMP – solid and sterile dosage plants, packaging rooms, medical device production, laboratories
✔ Others – cosmetics, precision instruments, data center cold aisles, battery plants

Rock Wool Series — framed panel options
Rock WoolFire performance reviewRock wool core panels are shown in the company catalogue. Compare the complete assembly, support requirements and applicable fire-test report before selection.
Single MgO-facedMoisture-proof + rock woolOne side MgO board over rock wool core — adds moisture resistance, good for walls near wet areas.
Double MgO-facedMoisture-proof both sidesMgO faces on both sides with rock wool core — best moisture protection, ideal for wash-down areas.
Double Gypsum-facedSmoothest finishGypsum faces both sides over rock wool — the smoothest, flattest surface for high-class cleanroom walls.
Honeycomb Series — ultra-flat & light
MgO Alu. HoneycombUltra-flat & strongMgO faces with aluminum honeycomb core — ultra-flat, lightweight and strong. Premium choice for high-end walls.
MgO Paper HoneycombLight & economicalMgO faces with paper honeycomb core — light, strong and economical for partitions and ceilings.
Gypsum Alu. HoneycombSmooth & lightGypsum faces with aluminum honeycomb core — very flat, light and looks clean. Good for ceilings.
MgO Series — moisture & impact resistant
Hollow MgO GridLight & rigidHollow MgO grid core — light yet rigid, with good moisture resistance. Good for wet and wash-down areas.

Wall Panels and Ceiling Panels: What Changes?
Send separate wall and ceiling schedules when requesting a quotation. For ceilings, specify the support arrangement, penetrations and maintenance access requirements, and request an assembly-specific allowable-load assessment. Thickness alone does not establish a ceiling load capacity or the cleanroom's ISO class.
What to Include in a Cleanroom Panel Quote
Include the destination country, room use, wall and ceiling area, panel dimensions, core and face requirements, doors and windows, joint details, cleaning agents, required test reports and delivery terms. State which accessories and installation services should be included.
