Color steel composite duct is a new type of air duct that combines color steel plates and insulation materials, and is used in ventilation systems in the construction and industrial fields.

Color steel composite duct is an air duct composed of color steel plate and insulation material. It usually includes the following layers:
Inner layer: Color steel plate or aluminum foil with antibacterial coating, used to protect insulation materials while providing a smooth inner surface for easy air circulation and cleaning.
Insulation layer: High efficiency insulation materials such as polyurethane, phenolic resin, polystyrene, inorganic materials, extruded polystyrene or glass fiber are used to reduce thermal losses and improve energy utilization efficiency.
Outer layer: Color steel plate, providing strength and beautiful appearance, while also having good corrosion resistance and weather resistance.

Color steel composite ducts are used in ventilation systems of various buildings, including but not limited to:
Commercial buildings: such as shopping centers, hotels, office buildings, restaurants, etc.
Industrial plants: such as electronics factories, pharmaceutical factories, food processing factories, etc.
Public facilities: such as hospitals, schools, sports centers, exhibition halls, etc.
Residential buildings: such as villas, apartments, etc.
