Product Details
Hollow glass magnesium sandwich panel also known as hollow magnesium oxide cleanroom panels, are a structural upgrade from traditional solid magnesium oxide panels. They are made from inorganic magnesium oxide (MgO), magnesium chloride, and plant fibers, molded into hollow profiles using a special mold, and then composited with color-coated steel sheets. This unique hollow design allows them to retain Class A fire resistance, moisture resistance, and corrosion resistance while significantly reducing weight and greatly improving sound insulation, heat insulation, and cable concealment. It is the preferred solution for high-end cleanroom projects and fireproof partitions worldwide.
Structural Form
- Core Structure: The panel cross-section has a continuous rectangular or elliptical hollow structure (similar to corrugated reinforcing ribs). This design, known in materials mechanics as the I-beam principle, maximizes bending strength while reducing weight.
- Composite Process: High-strength, environmentally friendly polyurethane adhesive is used to continuously composite the upper and lower layers of aluminized zinc-coated steel sheets with the hollow magnesium oxide core material under high temperature and pressure on a continuous production line.
- Connection Method: Standard tongue and groove joint. Conduit holes are typically pre-drilled at the interface, and combined with an embedded aluminum profile keel system, it achieves an aesthetically pleasing, screwless appearance with excellent airtightness.
- Surface Treatment: Surface materials can be anti-static color-coated steel sheets, stainless steel sheets, or anti-fingerprint coated sheets to meet different cleanliness levels.

Features of Hollow Glass Magnesium Sandwich Panel
- A1 Grade True Fire Resistance: Pure inorganic core material, non-combustible, smokeless, and non-toxic when exposed to fire, with a melting point exceeding 2800°C, making it a core material for firewalls and escape routes.
- Breathable Humidity Regulation: Magnesium oxide material has a unique microporous structure that can moderately regulate indoor humidity (moisture absorption and desorption) according to changes in ambient temperature and humidity, preventing condensation and creating a comfortable indoor microenvironment.
- Convenient Hollow-Cavity Wiring: The internal cavity allows for direct installation of electrical wires, cables, network cables, and monitoring conduits without the need for additional trenching or cable trays, significantly reducing electromechanical installation costs and maintaining wall integrity.
- Superior Weather Resistance: Resistant to acids and alkalis, insects, and aging. Its service life far exceeds that of ordinary color-coated steel sheets in corrosive environments such as coastal areas with high salt spray or chemical industrial parks.
- High Flatness and Rigidity: The I-beam design of the hollow structure maintains extremely high rigidity even with a relatively thin thickness, resulting in a flat wall surface without any unevenness.
Advantages of Hollow Glass Magnesium Sandwich Panel
- Lower Overall Cost: Compared to solid magnesium oxide panels, the hollow structure saves approximately 30% of raw materials, reduces transportation and installation difficulties, and eliminates the need for pre-embedded conduits within the wall, making it more cost-competitive overall.
- Highly Efficient Construction: Lightweight and high-strength (approximately 70% the weight of solid boards), combined with dry-layout tongue-and-groove connections, it can be moved and installed by a single person, making construction 5-10 times faster than bricklaying.
- Compliance Guarantee: Fully meets international cleanroom standards such as FDA, GMP, and ISO14644, as well as the most stringent fire safety regulations in various countries (such as Middle Eastern Civil Defense, NFPA).
- Green and Environmentally Friendly: Production produces no industrial waste, no formaldehyde, benzene, or other harmful substances are released during use; it is recyclable and meets LEED green building certification requirements.
Application Scenarios
High-Level Cleanrooms: Biopharmaceutical GMP workshops, hospital operating rooms (ORS), ICU wards, semiconductor chip manufacturing cleanrooms, and aseptic food packaging rooms.
Public Fireproof Partitions: Hospital corridors, school classrooms, shopping mall fire compartments, subway tunnel walls, and airport partitions.
Electronic Communication Equipment Rooms: Data Centers (IDC), server rooms, communication base stations (utilizing their electromagnetic shielding and cabling advantages).
Special Industrial Plants: Lithium battery production workshops, chemical explosion-proof areas, food processing plants (high requirements for mold and bacteria resistance).
Modular Buildings: High-end prefabricated container houses, medical mobile units, mobile nucleic acid testing laboratories.
