Fire-retardant board ducts are a type of fire-resistant material specifically used in construction projects for ventilation or smoke exhaust ducts. New Long fire-retardant 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 much lower than glass, clay, and ordinary concrete. The strength of the gypsum board is over twice that of regular gypsum boards. 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 boards are manufactured using high-quality fire-resistant quartz powder, flame-retardant minerals, supplemented with cement and various additives as raw materials. They are reinforced with high-quality refractory composite fibers and other mineral fibers, and are processed through special techniques such as molding, pressure application, high-temperature treatment, and steam curing.

       II. Product Features:
       1. Lightweight with high strength: The fire-resistant board duct has a unique construction, significantly lighter than conventional concrete or clay bricks, and boasts high flexural strength; it is much lighter than traditional gypsum board, with strength over twice as much. Particularly, the fire-resistant board duct excels in engineering applications as a smoke exhaust system or a combined exhaust and smoke exhaust system that withstands external pressure, thanks to its high strength, low self-weight, good elongation, and strong seismic resistance.
       2. Fire Retardant: After the fireboard is installed, it boasts excellent stability and integrity, with excellent fire resistance. It can extinguish fires at their initial stage, effectively isolating the flames. As the fire-retardant fibers are inorganic materials, they are non-flammable and do not emit harmful gases at high temperatures. This represents a proactive fire prevention approach, where prevention is better than cure!
       3. Easy Processing: Huachengxing fire-resistant board ducts can be processed at will (planing, sawing, nailing, drilling), offering more design options!
       4. Load-bearing Adaptability: The fire-resistant panel duct has high inherent strength and can withstand certain wind load pressures.
       5. High Durability: Fire-retardant plywood ducts are made of inorganic silicate calcium materials, which are not prone to aging or weathering. They also offer excellent anti-mold and anti-corrosion properties, and will not deform even when exposed to water. They are 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 during production, featuring the characteristics of a new type of green building material with zero pollution and no radioactive substances.

       Fire-resistant gypsum board ducts are commonly used in self-supporting ducts, countertops, interior and exterior walls of buildings, fire-retardant coatings on steel columns and beams, network floors, tunnels, and wall panels for indoor construction projects, home decoration, ceiling suspended ceilings, partition walls for commercial and industrial projects. Construction units, design units, and construction units can choose this product based on the specific project requirements. Fire-resistant gypsum board ducts are a special type of fire-retardant material, widely used in many cities. Main specifications: 1220*2440*9, 12mm. If customers require other sizes, the company can cut them on behalf of the customer, and special specifications can be arranged for processing.
