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 (A2), PU, phenolic or honeycomb. It is manufactured through heating, pressing and curing.
Key features
✔ High strength: reinforced frame and corner fittings, high bending capacity (approx. 0.89 kN/m² for 50mm)
✔ Fire safety: Fire performance review rock wool core, up to 1.0h+ fire resistance
✔ Flat & airtight: high flatness (≤1mm diagonal tolerance), tongue & groove or center aluminum connection with sealing strips
✔ Customizable: modules 980/1160/1180/1200mm, custom sizes, pre-cut for doors/windows/pass boxes
✔ Material options: PE polyester, PVDF, stainless steel, anti-static faces; rock wool, PU, phenolic, honeycomb cores
Typical specifications: Thickness 50/75/100/150mm; max length 10,000mm; face 0.426–1.0mm.
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 — fireproof & strong
Rock WoolFire performance reviewA2 fireproof core — first choice for GMP pharmaceutical and high fire-safety cleanrooms. Strong and soundproof.
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.
Magnesium OxysulfateHigh strengthMagnesium oxysulfate core — strong and moisture resistant. Good for heavy-duty walls.

More Face Materials
Hand-made panels also give you real choice on the surface — stainless steel or color-coated steel, matched to your industry and hygiene needs. Face thickness 0.426–1.0mm (stainless SUS304/430 available).
Stainless SteelFood, medical, wash-downSUS304/430 — hygienic, corrosion resistant and easy to clean. First choice for food, medical and wash-down areas.
PE PolyesterEconomical standardStandard economical coating — good for general cleanrooms where budget matters.
PVDF FluorocarbonWeather & chemical resistantSuperior weather and chemical resistance — ideal for coastal or corrosive environments.
HDP PolyesterHigh durabilityHigh-durability polyester coating — longer service life with better scratch resistance.
Anti-StaticElectronics / ESD areasDissipates static charge — protects electronics and sensitive components during production.
ConductiveESD-sensitive zonesESD-safe conductive surface — for static-sensitive assembly and testing zones.
Salt-plated (SV)Coastal / corrosiveCorrosion-resistant salt coating — for coastal and humid regions.
Aluminum / GalvalumeLight & corrosion resistantLightweight and corrosion resistant — low maintenance with a clean metallic look.
Panel Thickness Guide
Choose the right panel thickness for your walls, ceilings and cold rooms — the thicker the panel, the better the insulation and strength, but the heavier and more expensive it gets.
50mm
Partition Walls
The standard thickness for cleanroom partitions. Light, economical and easy to install — enough insulation and air-tightness for ordinary clean areas (ISO 8–9).
Best for: general partition walls in packaging rooms, food workshops and normal laboratories.
75mm
Ceiling Panels
The most common thickness for cleanroom ceiling systems. Stiffer and flatter than 50mm, so ceilings stay straight under their own weight, lights and ductwork — without sagging.
Best for: cleanroom ceilings, corridors and return-air plenums.
100mm
Insulated Walls
A thicker core means much better thermal insulation (lower heat transfer). Use it for walls next to the outside or between hot and cold zones — it saves energy and prevents condensation.
Best for: exterior walls of cleanrooms, temperature-controlled rooms and cold/hot aisle separation.
150mm
Cold Rooms / Heavy Duty
The heaviest option. The thick insulation keeps low temperatures (down to about -20°C) with low energy consumption, and the strong core can carry heavy loads for demanding partitions.
Best for: cold storage rooms, low-temperature cleanrooms and heavy-duty production partitions.
Application Scenarios & Recommended Panels
