The raw materials used in inorganic glass steel ducts are all inorganic materials, which do not burn when exposed to fire, offering superior fire resistance. They feature lightweight, high strength, non-flammability, resistance to aging, corrosion resistance, low resistance, good sealing performance, attractive appearance, easy installation, and long service life.

Inorganic glass fiber ducts are resistant to corrosion from acids, alkalis, salts, and can adapt to various regional climatic conditions. Especially in coastal areas with high salt content in the air and industries such as chemicals, tobacco, and chemical fibers that contain or are associated with volatile substances, their superior corrosion resistance is more pronounced.
