Fire-resistant board ducts are a type of fire-resistant material specifically used for ventilation or smoke exhaust ducts in construction projects. New Long fire-resistant board ducts are a new type of green building material with high stability. They are primarily composed of fibers, silicate calcium minerals, and refractory materials, rich in flame-retardant substances, and have a thermal conductivity coefficient significantly lower than glass, clay, and regular concrete. The strength of the gypsum board is more than double that of ordinary gypsum board. They feature high fire resistance, non-pollution, long service life, and easy installation, and are widely used in the fire protection systems of various buildings.

       I. Manufacturing Process:New RidgeFire-resistant duct board is manufactured using high-quality fire-resistant quartz powder, flame-retardant minerals, supplemented with cement and various additives as raw materials. It is reinforced with high-quality refractory composite fibers and other mineral fibers, and is produced through special processes such as molding, pressure application, high-temperature treatment, and steam curing.

       II. Product Features:
       1. Lightweight with High Strength: The fireproof board duct has a unique structure, significantly lighter than conventional concrete or clay bricks, with high flexural strength. It is also twice as strong as traditional gypsum boards while being much lighter. Particularly, fireproof board ducts excel in engineering applications as exhaust systems or combined exhaust and smoke evacuation systems under external pressure, showcasing their high strength, low self-weight, good elongation, and strong seismic resistance.
       2. Fire Retardant and Flame Retardant: After the fireproof board is installed, it boasts superior stability and integrity, with excellent fire resistance. In the event of a fire, it can extinguish the flames at their origin, ensuring pipe isolation. As the flame-retardant fiber material is inorganic, it is non-flammable and does not emit harmful gases at high temperatures. This represents a proactive fire prevention approach—prevention is better than cure!
       3. Easy to Process: Huachengxing fire-resistant board ducts can be processed freely (planed, sawed, nailed, drilled), offering more design options!
       4. Load-bearing Adaptability: The fire-resistant board duct has high strength and can withstand certain wind load.
       5. High Durability: Fire-resistant board ductwork is an inorganic silicate calcium material, which is not prone to aging or weathering. It also has excellent anti-mold and anti-corrosion properties, and will not deform even when exposed to water. It is a durable and high-performance building material, with a normal service life that can match the lifespan of various types of buildings.
       6. Green Building Materials: Fire-resistant ductwork produces no pollutants or waste during production, featuring the characteristics of zero pollution in new green building materials, without radioactive substances.

       Fire-rated ductwork is commonly used in suspended duct systems, countertops, interior and exterior building walls, steel column coatings, network flooring, tunnels, and wall panels for indoor construction projects such as home decoration, ceiling suspended ceilings, and partition walls for commercial and industrial buildings. Construction units, design units, and construction units can select this product based on the specific project requirements. Fire-rated ductwork is a special fire-resistant material that is widely used in many cities. Main specifications: 1220*2440*9, 12mm. If customers require other dimensions, the company can assist in cutting, and special specifications can be arranged for processing.
