In building fire protection systems, fire dampers act as "safety sentinels" on ventilation and air conditioning ducts. They operate silently under normal conditions, ensuring unobstructed airflow; however, once a fire breaks out and the smoke temperature

Scientific maintenance and management can significantly improve the corrosion resistance of single-layer louver vents and ensure their long-term stable operation.

In modern industry, medical, food, and household appliance fields, flexible hoses are not only channels for fluid transmission but also crucial barriers ensuring the purity, safety, and stability of the contents.

Against this backdrop, metal oval ducts, with their unique geometric advantages, have become an ideal solution to the contradiction between "space and efficiency"—they inherit the low-resistance characteristics of circular ducts and possess the flat adapt

In building HVAC, industrial exhaust, and cleanroom projects, ductwork serves as the core channel for airflow, and its cross-sectional shape directly affects system resistance, space occupancy, and installation efficiency.

In modern architecture, especially in the design of commercial offices, high-end residences, and public spaces, interior ceiling height has become a crucial indicator of spatial quality.
