1. Make life safer by improving safety. Through the establishment and improvement of internal control systems such as organization construction, system construction and process design, the air duct has formed a relatively strict risk control system.

With such a high standard for the air duct, there will be no problems in the safety issues, which greatly reduces the safety risks and allows us to enjoy the pleasure brought by the air duct.

2. Save a lot of engineering materials: the connecting bolts were produced according to the construction budget of using section steel to fix the pipe, which was about 40000 kg in 2001, and about 10000 sets of bolts were installed by using the construction process of the production line of the flange air duct with the same plate.

3. Composite air duct products have good compatibility and high degree of standardization. Full-automatic rectangular air duct production line has won many customers.

4. The ventilation loss is small. The quality of a product depends not only on its function but also on its consumption coefficient.

5. The project inspection is convenient, which is more helpful for customers to solve the maintenance problems in daily use.
