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.

Lightweight and high strength: Color steel composite air ducts are lightweight, about one-third the weight of iron sheet air ducts, reducing the load on buildings while having high strength and stiffness, capable of withstanding large wind pressures.
Thermal insulation: The insulation layer adopts high-efficiency insulation materials with low thermal conductivity, good insulation effect, and effectively reduces cold and heat losses.
Fireproof and flame retardant: Both color steel plates and insulation materials have good fire resistance, meeting the requirements of building fire prevention.
Beautiful and durable: The outer color steel plate has a smooth and beautiful surface, diverse colors, and meets the aesthetic requirements of modern architecture. At the same time, it has good corrosion resistance and weather resistance, with a long service life.
Easy installation: The color steel composite duct is prefabricated in the factory and assembled on site, making installation simple and fast, reducing the difficulty and duration of on-site construction.
Environmental protection and energy conservation: Color steel composite air ducts do not produce harmful substances during production and use, meeting environmental requirements. At the same time, they have good insulation and heat insulation effects, reducing energy consumption.

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.
