Machine-made MOS panel (Type 50, 1150 type): magnesium oxysulfide sandwich panel
The machine-made MOS panel is the machine-made magnesium oxysulfide tongue-and-groove panel, Type 50, 1150 type. It is the machine-made member of the MOS family, made by continuous automated roll forming, and this page states its listed dimensions together with the source-site product wording that belongs to this panel, with its attribution stated every time.

What this model is
Machine-made panels, as described in the source material, use colour-coated or stainless-steel face sheets with different cores and high-strength adhesive, continuously roll-formed into a composite panel for cleanroom walls and ceilings. This model is the oxysulfide-core member of that route. Its core is integrally moulded in upper and lower layers within a mould, according to the source-site product wording, requiring minimal glue for bonding, which the same wording presents as reducing deformation from pressure or thermal expansion and contraction.
The source-site product wording for this panel makes several strong claims, and each is stated here as source-site product wording, not as a test conclusion: a guarantee of absolutely no halogen reversion; an arch-bridge structural principle that disperses localised stress; a load-bearing capacity twice that of hollow glass-magnesium panels; water resistance, moisture-proofing, and resistance to condensation and humid air, with no halogen reversion and no white crystalline substances released; and a molecular structure described as stable and resistant to ageing, unaffected by laboratory humid and rainy conditions or immersion in water, and resistant to corrosion, bacteria, insects, and termites.
A buyer should read those claims as the supplier's product wording and ask for the test documents behind any claim the project will rely on. This site does not convert product wording into a verified performance guarantee, and the inquiry page lists the certificate and document questions to ask for this model.
Listed dimensions, fire wording, and durability wording
| Item | Listed value |
|---|---|
| Type | Type 50, machine-made, 1150 type |
| Core family | MOS (magnesium oxysulfide, as listed) |
| Regular width | 1,150 mm |
| Thickness range | 50 to 150 mm |
| Joint | Tongue-and-groove installation |
| Fire wording (source-site product wording) | GB8624-1997 Class A, non-combustible rating |
| Local high-temperature wording (source-site product wording) | Withstands local exposure above 1,000 degrees without heating the back surface; burnt area does not expand or spread; no smoke, toxins, or pollutants released during combustion |
| Flatness wording (source-site product wording) | Flatness error controlled within 0.1 mm by one-time cutting with imported electronic precision saws |
| Service-life wording (source-site product wording) | Service life of not less than 20 years |
The flatness wording deserves a buyer's attention because it is a visible quality: the source-site wording contrasts the one-time cutting error of 0.1 mm with secondary manual adhesion errors exceeding 1 mm that can leave visible seams after processing. Whether that contrast holds for a given order is a matter for the supplier's quality documents, not for this page to guarantee.
The brochure and source-site wording for this model also describes the panel as a Class A fire material with good flatness, thermal insulation, non-toxicity, and light weight, with a proprietary-formula core described as non-moisture-absorbing. That description is stated as brochure and source-site wording.
No humidity figure is stated on this page, and the humidity-selection confirmation page explains the model-by-model confirmation that replaces any figure.
Installation and site work
The tongue-and-groove joint of this model is made for fast site installation at a uniform 1,150 mm module. The source material describes machine-made installation in general marketing terms as faster than traditional panels, with a labour-saving claim attributed to customer material. This page does not repeat a speed or labour-saving figure as a fact for this model, because a site's actual installation speed depends on the room, the crew, and the openings, not on the panel alone.
For rooms with many openings or non-standard widths, compare this model with the handmade MOS panel, which offers a width range of 300 to 1,180 mm and pre-cut openings. For rooms with a regular layout and a premium on installation speed, this machine-made model is the natural first comparison. The handmade-versus-machine-made guide sets out the trade-off without inventing a winner.
Where this model fits
The source material's customer-advice wording favours sulfomagnesium panels for laboratory rooms, and the machine-made MOS panel is the machine-made route into that advice. The laboratory application page states that advice with its attribution, and a buyer should confirm the model, the joint, and the room requirements together.
The core-selection guide places this model among the magnesium cores: MOS for the sulfate-family advice, hollow glass-magnesium for the hollow-core system, and glass-magnesium rock wool for higher fire and sound-insulation requirements. No core is presented as universally best; the room decides.
