Magnesium oxide composite duct is a duct system composed of two layers of high-strength inorganic materials and one layer of insulation material.

It has the following characteristics:
Light weight and high strength: Magnesium oxide composite ducts are lightweight, easy to handle and install, and have high strength to withstand large wind pressures.
Non combustible and good fire resistance: Magnesium oxide composite ducts are made of non combustible inorganic materials, with fire resistance reaching Class A of GB8624-1997 standard, and belong to non combustible materials.
Good sound insulation and thermal insulation effect: It has good sound insulation and thermal insulation performance, which can effectively improve indoor environment.
Moisture resistant, water-resistant, and long service life: It is not easy to rust or corrode in humid environments, and can maintain stable performance and extend service life.
Green and environmentally friendly, pollution-free: In the process of production, manufacturing, installation, and use, no substances that pollute the environment are produced, which belongs to green and environmentally friendly building materials.

Magnesium oxide composite ducts are applied in the fields of construction, decoration, fire protection, etc., and are particularly suitable for the following places:
Places with high pedestrian flow, such as restaurants, hotels, shopping malls, etc., can meet the high requirements for air quality and safety.
Damp environment: such as basements, civil air defense projects, mines, etc., can maintain stable performance in damp environments.
Industrial and Civil Buildings: Suitable for various types of industrial and civil buildings as well as other places with special requirements, such as hospitals, food processing plants, etc.
