Cleanroom Magnesium Oxysulfide Panels are engineered wall and ceiling panels used to build controlled environments with very low levels of dust, microbes, and chemical vapors.

They use a magnesium oxysulfide core with cleanroom‑grade steel or stainless steel surfaces, providing smooth, low‑VOC, easy‑to‑disinfect finishes suitable for sterile and high‑purity areas.

Core blocks form when magnesium oxide reacts with calibrated magnesium sulfate brine and functional additives. Curing locks in a rigid, stable magnesium oxysulfide base.

Manufacturers bond these cores with pre‑coated metal skins on continuous or batch press lines. After compression and full curing, boards get trimmed to custom sizes, then sealed along all cut edges with cleanroom‑grade sealants.

These wall boards boast rigid outer surfaces that stand up to knocks and impacts. Walls stay perfectly even, with far fewer dents and cracks forming around door cutouts and installed machinery.

That’s not their only upside. They hold strong against fire, dampness and regular chemical sanitizers, while releasing barely any VOCs and retaining consistent dimensions year‑round.

All these traits let manufacturing spaces sustain their required clean classification and breeze through compliance audits without hassle.

Yes. Magnesium oxysulfide is an inorganic, non‑combustible material, so these panels can achieve strong fire performance compared with many organic‑core systems.

In practice, panels are tested to relevant fire standards (such as EN or ASTM methods) and can be specified as part of fire‑rated cleanroom walls and escape routes, depending on local codes.

Compared with gypsum board or basic metal cladding, Magnesium Oxysulfide Panels typically offer higher strength, better moisture resistance, and more durable, seamless‑looking cleanroom surfaces.

They reduce the risk of warping, mold growth, and frequent repairs, while delivering better overall fire and hygiene performance than many conventional partition systems in critical areas.

Cost varies with thickness, facing (painted steel or stainless steel), quantity, and project location, so most suppliers provide project‑specific quotations rather than a single list price.

In many projects, Magnesium Oxysulfide Panels sit between basic sandwich panels and premium stainless systems on initial cost, but can lower lifecycle cost thanks to durability and fewer replacements.

Installation usually starts with setting out and fixing the steel or aluminum framework, then lifting panels into place and mechanically fastening or locking them to the supporting structure.

Joints are sealed with cleanroom‑compatible sealants or profiles, and details around doors, windows, and ceilings are closed so the final envelope meets air‑tightness and cleaning requirements.

Depending on the manufacturer, panels can be tested for fire performance, mechanical strength, and thermal properties according to EN, ASTM, or GB standards and relevant local codes.

For cleanroom projects, designs are selected to support ISO 14644 classifications and GMP requirements, including low particle shedding, low VOCs, and compatibility with common disinfectants.

Yes. Panels can typically be customized in thickness, core density, facing type (painted steel, SS304, etc.), surface color, and edge details to match your wall and ceiling layout.

Manufacturers can also pre‑cut openings for doors, windows, and services, and coordinate with cleanroom accessories such as covings, air returns, and integrated pass‑throughs where required.

Common panel widths are typically in the range of 900–1200 mm, with lengths often up to 3–6 m, depending on transport and handling limits on site.

Thicknesses such as 50 mm and 100 mm are widely used for walls, while thinner options can be used for ceilings; custom sizes are usually available for larger projects.

Magnesium oxysulfide cores are inorganic and can be produced with relatively low VOC emissions; finished panels are designed to meet cleanroom limits for off‑gassing and indoor air quality.

Long service life, good durability, and the possibility of recycling metal facings at end‑of‑life can also help reduce the overall environmental footprint compared with short‑life solutions.

Common projects include pharmaceutical and biotech factories, hospital rooms, medical device workshops, semiconductor and electronic workshops, food production lines and cosmetic plants.

Factory owners pick this panel because it balances easy sanitization, reliable fire safety and stable structure all at once. It fully fits the strict quality rules like GMP and ISO required in these industries.

Daily upkeep for these panels is simple and straightforward. You just need to clean them routinely with standard disinfectants, and check for surface damage or cracked sealants on a regular basis.

Any dents or loose joints should be fixed in a timely manner. Make sure panel surfaces, corners and drilled openings stay smooth and fully sealed so the cleanroom keeps its required classification.
