1. Good fire resistance is also one of the reasons why galvanized air ducts are widely used in engineering.

2. The products are mostly used in large shopping malls, office buildings, subway stations, large supermarkets, and modern factories. People's requirements for quality of life and environment are getting higher and higher. When building buildings and some factories, they will consider whether the ventilation system is good. In addition, when planting some plants at home, good ventilation is also required to ensure the vigorous growth of plants.

3. The inner wall of the galvanized air duct is smooth, with low resistance, low ventilation loss, reduced energy consumption, and saved operating costs. It has good air tightness and airtightness, and high pressure resistance.
