Product Details
Cleanroom hollow magnesium oxide board is a new type of cleanroom-grade steel panel product specifically developed for high-cleanliness environments. The product uses high-quality color-coated steel sheets, galvanized steel sheets, anti-static sheets, or stainless steel sheets as the face panels on both sides, with two layers of 5mm fire-resistant MgO sandwich panels and a fire-resistant MgO inner spacer as the core material. It is composite-formed using a multi-functional continuous production line for steel sandwich panels. The MgO core material is mainly composed of inorganic materials such as high-purity active magnesium oxide (MgO), reinforced with a medium-alkaline fiberglass mesh and filled with lightweight materials, making it a green and environmentally friendly new type of non-combustible decorative material.
Depending on the production process, hollow MgO sandwich panels are divided into two types: machine-made and handmade. Handmade panels use a cold-drawn profile frame on all four sides, with the MgO mesh spacer glued internally, resulting in precise dimensions and good flatness. Machine-made panels are formed in one continuous automated production line.

Performance Advantages
A1 Fire Resistance, Highest Safety Level
The core material of the cleanroom hollow magnesium oxide board is an A1-grade non-combustible material (some indicators reach A2 grade), belonging to a high-grade fire-resistant building composite board. It will not melt during combustion, nor will it produce high-temperature decomposition drips. Testing shows that the product’s fire resistance limit can reach over 1.5 hours, effectively blocking the spread of flames and providing a solid guarantee for life and property safety.
Excellent Moisture and Water Resistance
The magnesium oxide sandwich panel for cleanroom uses inorganic materials as its main raw material, exhibiting excellent moisture resistance and allowing normal use in humid environments. The board has extremely low expansion and contraction rates, does not crack, deform, freeze, or rot, and remains stable even in high-humidity clean environments.
Lightweight and High-Strength, Good Flatness
The product is lightweight and high-strength, with a tensile strength of up to 5600 kg/cm². Hand-made boards combined with cold-drawn profile frames result in high overall strength and good flatness; machine-made boards have a smooth and aesthetically pleasing surface with accurate geometric dimensions. The product boasts excellent seismic resistance and adapts to various building conditions.
Superior Sound and Thermal Insulation Performance
The panels offer superior sound insulation, heat insulation, and thermal insulation properties, with a thermal conductivity as low as 0.044 W/(m·K), effectively maintaining a constant temperature and humidity environment in cleanrooms and reducing operational energy consumption.
Environmentally Friendly and Safe, Free of Harmful Substances
The product releases no formaldehyde or other harmful substances during production and use, making it green and environmentally friendly. Simultaneously, the product offers dustproof, antistatic, and antibacterial effects, meeting the multiple functional requirements of cleanrooms.
Facilitates Cable Laying
The core material of the panels has a hollow structure, making it convenient for concealed wiring during electrical construction when used in workshop partitions, significantly improving construction efficiency.
