Handmade MOS panel (Type 50): magnesium sulfate sandwich panel
The handmade MOS panel is the handmade magnesium sulfate panel, Type 50. It is the handmade member of the MOS family on this site, and its model page states only the facts listed for this handmade model. Where the source material gives a brochure self-description, this page states it as a brochure self-description, not as a tested conclusion.

What this model is
This is a handmade sandwich panel, built around a galvanised steel keel frame with edge wrapping, in the handmade construction route that the source material describes as offering better load-bearing, embedded conduits, pre-cut openings, and easy disassembly, at a higher cost than machine-made panels. The panel's core family is MOS, and its listed name is the magnesium sulfate panel. The sulfate name and the oxysulfide name are kept distinct on this site: this handmade model is listed under the sulfate name, while the machine-made MOS model is listed under the oxysulfide name, and the naming guide explains that distinction.
The brochure self-description for this model states that the maker is the only domestic manufacturer of pure magnesium sulfate panels, producing with 100 percent magnesium sulfate, and that the panel does not absorb moisture. The brochure also states that the panel's strength is far higher than other magnesium sulfate panels on the market. All three statements are brochure self-descriptions. They are recorded here with that attribution because a buyer should know what is a maker claim and what is an independently tested fact, and this site does not convert maker claims into test conclusions.
The source material also lists a 2019 formulation point for the sulfate-based glass-magnesium board: a formulation without chloride ions, presented as addressing the moisture absorption and shrinkage problems of traditional oxychloride boards. That formulation point belongs to the sulfate board family story, and it is stated here as a brochure formulation claim. It is not extended to the standalone hollow board on this site, for which no chloride claim is made.
Listed dimensions and joint
| Item | Listed value |
|---|---|
| Type | Type 50, handmade |
| Core family | MOS (magnesium sulfate panel, as listed) |
| Regular width | 300 to 1,180 mm |
| Regular thickness | 50 mm |
| Custom thickness | 75 mm and 100 mm |
| Length | By project |
| Joint | Tongue-and-groove connection, or middle-aluminium connection |
The width range and the thickness options are the handmade route's flexibility: a room that needs a non-standard width, or a panel that must fit an existing opening, can be addressed within the listed range without forcing a uniform module. Length is by project, which means the inquiry must state the room dimensions rather than assuming a stock length.
The joint choice matters for the room as well as for installation. A tongue-and-groove connection and a middle-aluminium connection give different joint appearances and different site work, and the joint-methods page lists only the listed joint facts for handmade panels, with no drawing dimensions. State the joint your project specifies, or ask which joint the supplier recommends for your room, as a separate inquiry question.
Construction, openings, and site work
Handmade construction, as described in the source material, uses a keel frame with edge wrapping and ABS corner pieces, and it supports embedded conduits and pre-cut openings. For a laboratory or biopharma room, that matters: services, outlets, and pass-throughs can be planned into the panel rather than cut on site, and a panel that must be removed later for maintenance can be disassembled and refitted.
That flexibility is also the reason handmade panels cost more than machine-made panels, according to the source material. A buyer comparing this model with the machine-made MOS panel should compare the full cost of the room, including site cutting, opening work, and later disassembly, not only the panel price per square metre — and this site states no price, so that comparison must be made from the supplier's reply, not from this page.
For installation, the source material lists the handmade joint options above and describes the handmade route as suited to high-standard cleanrooms. No installation speed figure is stated for this handmade model, and no installation instruction is given on this page beyond the joint options. Ask for the installation guide for this model at inquiry if your site team needs it.
Where this model fits
The source material's customer-advice wording favours sulfomagnesium panels for laboratory rooms, citing antibacterial, anti-mould, easy-cleaning, Class A fire, and acid-and-alkali-resistant qualities as customer advice. That advice is stated with its attribution on the laboratory application page, and it is the application context for this model. It is not a test conclusion for this model, and it does not replace a room-by-room confirmation.
The biopharma application page gives the parallel customer-advice wording for MOS panels in biopharma rooms: antibacterial, anti-mould, dust-free, tight joints, and easy cleaning, again as customer advice. A buyer selecting this model for a biopharma room should read that page and then confirm the model, the joint, and the room requirements together, rather than selecting on the core name alone.
Rooms that need a uniform 1,150 mm module and the fastest site installation should compare the machine-made MOS panel instead. Rooms that need varied widths, embedded services, or pre-cut openings should compare this handmade model first. The handmade-versus-machine-made guide sets out that comparison using only listed facts.
Inquiry checklist for this model
State the width within the 300 to 1,180 mm range, the thickness (50 mm, or custom 75 or 100 mm), the length by project, and the joint (tongue-and-groove or middle-aluminium). State whether embedded conduits or pre-cut openings are needed, and list them, because they are planned into handmade panels rather than added afterwards.
