Key Features
🔥 Class A1 Fire Resistance: Outstanding fireproofing performance. The magnesium oxide core is non-combustible, ensuring maximum safety for personnel and high-value equipment in case of fire.
💪 High Structural Strength: The unique hollow structure provides excellent load-bearing capacity and impact resistance. It is highly recommended for cleanroom ceilings (allows maintenance staff to walk on it).
💧 Moisture & Water Resistant: Unlike paper honeycomb or rock wool, the MgO clean room panel does not deform or degrade in high-humidity environments, preventing mold and bacterial growth.
✨ Smooth & Dust-Free Surface: Coated with antistatic or antibacterial paint, the surface prevents dust accumulation and is extremely easy to clean and sterilize.
⚙️ Lightweight & Durable: The "hollow" design significantly reduces the overall weight of the panel compared to solid MgO panels, making transportation and on-site installation much easier and faster.

Frequently Asked Questions
Q1: What is the difference between Hollow MgO and Solid MgO panels?
A: Both offer Class A1 fire resistance. However, the Hollow MgO panel features internal air gaps, making it significantly lighter than the solid version while maintaining high structural strength. This makes the hollow version easier to handle and install, saving labor costs.
Q2: Can this panel be used for cleanroom ceilings?
A: Yes, absolutely. Because of its high bending strength and load-bearing capacity, the 50mm hollow magnesium oxide panel is widely used as a walkable ceiling in cleanroom engineering, allowing maintenance personnel to walk safely above the cleanroom.
Q3: Can I customize the surface color and material?
A: Yes! While standard cleanroom white (off-white) is the most popular, we can customize the color coating or use stainless steel facing based on your specific project needs.
