Magnesium-system cleanroom panels: MOS, MgO, and hollow glass-magnesium board

This site covers one material family only: magnesium-system cleanroom panels. That means MOS (magnesium oxysulfide) sandwich panels, MgO (magnesium oxide) sandwich panels, and the hollow glass-magnesium board that the source site lists as a standalone board product. If your room needs a different core family, it is not described as a product of this site.

Which magnesium core fits your room?

Start from the core, not from a generic panel name. A MOS core is the sulfate-based magnesium core: the handmade MOS panel is listed as a Type 50 panel, and the machine-made MOS panel is listed as a Type 50, 1150-type tongue-and-groove panel. A hollow glass-magnesium core is the hollow board core used both as a standalone board and inside sandwich panels. A glass-magnesium rock wool core combines a glass-magnesium board layer with rock wool filling, for projects where fire protection and sound insulation requirements are higher.

The three cores are not interchangeable descriptions of one product. The source material keeps the sulfate name and the oxysulfide name as distinct wordings, and this site does the same: the naming guide explains where each wording belongs, and each model page states only the core that is listed for that model.

MOS core — handmade MOS panel (Type 50) and machine-made MOS panel (Type 50, 1150 type)
Hollow glass-magnesium core — handmade and machine-made hollow glass-magnesium panels (Type 50; machine-made in 1150 type)
Glass-magnesium rock wool core — handmade and machine-made MgO rock wool panels (Type 50; machine-made in 1150 type)

Handmade or machine-made magnesium panels?

Handmade panels are built around a galvanised steel keel frame with edge wrapping, and they can be supplied with embedded conduits and pre-cut openings. That construction suits rooms where the layout needs openings and later disassembly, and where a non-standard width is needed: handmade panels are listed at a regular width range of 300 to 1,180 mm, with a regular thickness of 50 mm and custom thicknesses of 75 and 100 mm.

Machine-made panels are continuously roll-formed tongue-and-groove panels. They are listed at a regular width of 1,150 mm and a thickness range of 50 to 150 mm, and their tongue-and-groove joint is made for fast site installation. Where a project values installation speed and a uniform 1,150 mm module, the machine-made route is the one to compare first.

The handmade-versus-machine-made guide on this site sets the two routes side by side using only the listed widths, thicknesses, joints, and installation facts. It does not invent a performance winner: the right route depends on the room, the openings, and the joint the project will actually use.

Three projects that used magnesium panels

The Jihua Laboratory project in Foshan, Guangdong, is listed as a research-laboratory project of 40,000 square metres using sulfomagnesium panels. The Guangzhou Quaker project in Guangzhou, Guangdong, is listed as a chemical-industry project of 35,000 square metres using magnesium-oxide rock wool panels and hollow magnesium-oxide panels. The Dongpeng Changsha base in Changsha, Hunan, is listed as a food-industry project of 50,000 square metres using stainless-steel magnesium-oxide cleanroom panels.

Each project has its own page on this site, and each page states only the project name, location, industry, area, and products that the project listing gives. No construction period, contract value, or cleanliness class is stated, because the listing does not give those fields.

The project pages are the only full project pages on this site. No other project is given a full page here, and no project photograph is described as a verified on-site photograph of that project.

Confirm before you order

Three confirmations belong in every magnesium-panel inquiry on this site. First, confirm the applicable humidity range for the exact model you are selecting: the source material records different humidity wordings for different magnesium models, and this site deliberately states no humidity figure, so the model-by-model confirmation is part of the selection, not an afterthought.

Second, ask for the certificate list for the model you are selecting. Certificates are available upon request, and this site states no certificate number, issuing body, or expiry date.

Third, before ordering, confirm the minimum order quantity and lead time for this model. No figure for either is stated on this site, and the inquiry page sets out the buyer questions to ask.
