Class A1 Fireproof Magnesium Oxysulfate Cleanroom Panel
For cleanroom construction, Magnesium Oxysulfate Cleanroom Panels from China Glostar factory are a highly suitable material, combining structural rigidity with excellent fire resistance. MgOS panels are made from a special sulfate-based magnesium cement, forming a "hollow grid" or solid structure, thus addressing the most common challenges in facility engineering: load-bearing capacity and utility integration.

Product details
The customized cleanroom panel is ideal for high-standard environments such as pharmaceutical GMP workshops, electronics factories, and hospitals. It features a Class A1 fire rating and provides mechanical strength sufficient to withstand foot traffic. It is an excellent choice for projects where safety, durability, and ease of electrical installation are critical.
Main Features and Advantages

A. A1 Fire Rating, Low Smoke Emission
Safety is paramount. The magnesium oxide sulfate core material is an A1-rated non-combustible material.
High Temperature Resistance: It can withstand temperatures up to 1200°C without losing structural integrity.
Low Smoke: In the event of a fire, the panels produce minimal smoke and no toxic gases, ensuring clear evacuation routes and complying with stringent international fire safety regulations.
B. Excellent Load-Bearing Capacity, Suitable for Walkable Ceilings
This is a significant feature of MgOS panels.
Load-Bearing: Unlike soft rock wool, the MgOS core material is strong and durable, possessing high compressive and flexural strength.
Walkable: When used as ceiling panels, it can support the weight of maintenance personnel, facilitating maintenance of HVAC equipment or filters. This eliminates the need for complex secondary grid structures, thus saving on construction costs.
C. Innovative Hollow Structure for Easy Wiring
One of the unique advantages of mechanically manufactured MgOS panels is their hollow or grid-like core structure.
Concealed Wiring: Pre-reserved channels within the core material allow electricians to easily run wires and conduits through the panels after installation or during assembly.
Aesthetically Pleasing and Clean: This eliminates unsightly surface-mounted conduits, maintaining the smooth, flush surface required for a dust-free cleanroom environment.
D. Excellent Thermal Insulation Performance
Despite its hard material, it has a low thermal conductivity. It effectively insulates the cleanroom environment from external temperature fluctuations, reducing the load on the air conditioning system and improving energy efficiency.
E. Corrosion and Moisture Resistance
Note: This is what distinguishes it from traditional magnesium oxide panels.
Our magnesium oxide sulfate formula eliminates the chloride ions present in traditional magnesium oxide (MgO) panels. This means there is no "halogen deliquescence" (moisture absorption) and no resulting steel plate rusting. It remains stable and durable even in humid environments.

Applications
Pharmaceutical GMP Ceilings: Where maintenance staff needs to access HEPA boxes and ductwork above the ceiling frequently.
Electronics Factories: For corridor walls that need to withstand cart traffic and impacts.
Data Centers: Where fire protection and wiring flexibility are critical.
Hospitals: Operating rooms and sterile corridors.



Why "Hollow" Matters for Modern Cleanrooms?
In traditional sandwich panels (like EPS or Solid Rockwool), running electrical wires for switches, sockets, or sensors requires cutting into the panel or running ugly conduits on the surface.
The Hollow Magnesium Oxysulfate Panel changes this game. The core is manufactured with longitudinal holes or a grid framework.
Effortless Integration: Installers can fish wires through these hollow channels seamlessly.
Structural Integrity: The grid shape actually reinforces the panel, acting like I-beams to resist bending.
Weight Reduction: While being strong, the hollow design prevents the panel from becoming excessively heavy, making installation manageable.

FAQ
Q: Is Magnesium Oxysulfate the same as Magnesium Oxide?
A: They are related but MgOS is the superior, updated version. MgOS uses magnesium sulfate instead of magnesium chloride, eliminating the risk of corrosion and moisture absorption that plagued older MgO panels.
Q: Can I walk on the ceiling panels?
A: Yes. When properly installed with the correct span and suspension system, the high-strength MgOS panels are designed to support the weight of maintenance personnel.
Q: Does the hollow structure affect fire performance?
A: No. The material itself is A1 non-combustible. The hollow structure reduces weight but the fire resistance remains superior.
Q: How heavy is the panel?
A: MgOS is heavier than foam panels but lighter than solid concrete. The density is typically around 230kg/m³. The hollow design helps keep the weight manageable for installation.
