Their steel structures are exceptionally strong and precisely manufactured. The entire production process was highly professional.
Luoyang Innovation Building Material Co., LTD manufactures Sulfur Oxygen Magnesium Purification Board as a premium composite solution for controlled environments. With its twin metal facings and magnesium oxysulfate core, our product offers exceptional moisture resistance and Grade A1 fireproof performance. This panel satisfies strict requirements with steel thickness options of 0.17mm to 0.6mm and core thicknesses of 50mm, 75mm, and 100mm. Our 50,000-square-meter production facility produces more than 2 million square meters a year, guaranteeing a consistent supply for major projects. With adjustable lengths and an ISO-9001 certification, the effective width ranges from 950 to 970 mm.

This advanced panel utilizes magnesium sulfate instead of traditional magnesium chloride. The sulfur-based formulation completely eliminates the sweating phenomenon that plagues conventional boards.
You won't experience moisture beads forming on panel surfaces. The chemical stability prevents steel plate corrosion even in humid conditions.
The inorganic core material combines fiber reinforcement with specialized fillers. This composition creates exceptional structural integrity while maintaining lightweight properties. You benefit from reduced building loads without compromising strength.

Fire Resistance Beyond Standards
Your facility receives Grade A1 non-combustible protection with fire endurance exceeding 1-2 hours. The panel maintains structural stability under extreme heat without sagging.
Moisture and Chemical Resistance
The low moisture absorption rate ensures dimensional stability. You can use these panels in areas with frequent chemical sterilization and high humidity levels.
Exceptional Mechanical Strength
Flexural and compressive strength reaches 2-3 times higher than traditional rock wool boards. This enables walk-on ceiling installations for maintenance accessibility.
Temperature Insulation and Energy Efficiency
The thermal conductivity coefficient minimizes heat transfer. You reduce operational costs through superior energy conservation performance.
Sound Insulation Properties
The dense core structure provides excellent acoustic dampening. You create quieter work environments in noisy industrial settings.
Lightweight Installation
Despite high density, the panel remains easy to handle. You achieve faster installation times with standard tongue-and-groove or aluminum profile systems.

Pharmaceutical and Biotech Cleanrooms
Your GMP-compliant facilities benefit from zero microbial growth potential. The inorganic nature provides no nutrients for bacteria or mold.
Microelectronics and Semiconductor Fabrication
Dust-free workshops require low outgassing properties. You protect sensitive silicon wafers with this contamination-free solution.
Food Processing and Cold Chain Facilities
Temperature differentials create condensation challenges. This Sulfur Oxygen Magnesium Purification Board moisture-proof characteristics prevent rot and rust in demanding conditions.
Hospital Operating Rooms and Laboratories
Sterile environments demand reliable performance. You maintain strict hygiene standards with surfaces that resist biological contamination.

Our intelligent production line ensures consistent quality. Each panel undergoes rigorous inspection protocols:
Peeling Strength Testing verifies bonds exceed 0.1MPa to prevent delamination. Chloride Ion Analysis confirms levels below 0.1% for corrosion prevention.
Flatness Measurements using laser leveling maintain surface deviation under 1mm per meter. This precision enables seamless cleanroom installations.
Combustion Performance Testing follows GB8624 international standards. Salt Spray Testing validates anti-corrosion performance in harsh environments.
Our 50,000-ton annual steel structure capacity supports integrated project delivery. You receive comprehensive solutions from design through construction.

Q: How does this differ from magnesium oxychloride boards?
A: The sulfur-based formulation eliminates moisture absorption and steel corrosion issues. You avoid the sweating phenomenon entirely.
Q: Can it support walk-on ceiling loads?
A: Yes, the high structural density and flexural strength accommodate maintenance access. It significantly outperforms rock wool in load-bearing capacity.
Q: Is special installation equipment required?
A: Standard systems work well, though professional cutting equipment helps with precise onsite adjustments due to higher density.
Q: Does it meet pharmaceutical industry standards?
A: Absolutely. Zero formaldehyde and zero asbestos content satisfy stringent VOC emission requirements for pharmaceutical applications.
Q: What advantage does it offer over rock wool panels?
A: While both achieve Grade A fire rating, this panel provides better structural stability under heat and eliminates the sagging effect common with rock wool.
