Steel Faced Magnesium Fireproof Duct Board






In the world of modern construction and industrial infrastructure, the paramount importance of fire safety cannot be overstated. As structures grow taller and more complex, the need for robust fire-resistant materials and systems becomes increasingly critical.
Among the various components that contribute to safeguarding these environments, HVAC (Heating, Ventilation, and Air Conditioning) systems play a pivotal role.
Within these systems, the utilization of cutting-edge materials is paramount, and one such innovation that stands at the forefront is Steel-Faced Magnesia Fire-Resistant Duct Panels.
// What Is Steel Faced Magnesium Fireproof Duct Board
Steel-faced Magnesia Fire-Resistant Duct Board is a cutting-edge solution in the field of HVAC (Heating, Ventilation, and Air Conditioning) systems.
This innovative duct board combines the unmatched fire resistance of magnesium oxide with the structural strength and durability of steel, creating a high-performance material that ensures both safety and efficiency in ventilation and ductwork.

Structural Analysis and Performance Introduction of Witten’s Finished Air Duct:

High Security
All materials used are non-combustible at A1-level, ensuring that the air duct’s fire resistance (integrity and insulation) fully complies with fire safety standards.
Wind pressure resistance exceeds 3000PA, significantly surpassing the national standard requirement of ≥1500PA.
Elevation Advantages
While meeting fire protection and heat insulation standards, the air duct maintains a low thickness, eliminating the need to reserve space for secondary winding.
Shortened Construction Period
The air duct incorporates its own fireproof insulation layer, eliminating the need for additional fireproof wrapping, which can reduce construction time by more than 2 times.
Aesthetic and Durable
The inner and outer walls of the air duct consist of corrosion-resistant metal plates, preventing corrosion and rust caused by moisture in the garage.
Unlike galvanized air ducts covered with rock wool and fireproof boards, issues like bulging, deformation, and cracking resulting from moisture absorption are eliminated.
Weight Reduction
Compared to galvanized air ducts covered with rock wool and fireproof boards, the weight of these air ducts is reduced by 50%, effectively reducing the structural load on the building and saving construction costs.

These panels find their primary application in air supply and smoke exhaust ducts that require stringent fire resistance specifications. They are commonly utilized in industrial, commercial, and institutional settings where fire protection standards are rigorously enforced.
These panels are especially crucial in scenarios where HVAC systems pass through fire protection zones, ensuring that even in the event of a fire, the ducts maintain their structural integrity and prevent the spread of smoke and flames.
In essence, steel-faced magnesia fireproof duct panels are the linchpin of fire-safe HVAC infrastructure, safeguarding lives and property by containing fire and smoke within designated areas.
