The manufacturing and processing of ventilation pipes, especially for some small and medium-sized enterprises and handmade companies, is not easy to survive for a long time. Because we are sure that the development trend of a company is inseparable from the development trend of corporate culture and brand strategy between the two. Although the core of today's air duct is still sheet iron, there are many shortcomings in engineering construction and maintenance due to the environmental protection, life limit, waterproof, sound insulation and noise reduction, load and other aspects of the air duct.
This creates a new commodity in large shopping malls to improve this difficulty. The display of new stainless steel duct is just used to the requirements of large shopping malls. According to the application and practical experience of many engineering projects, it is gradually undertaken by investors and real estate developers.

According to the materials, the air ducts in large shopping malls are generally divided into three categories: hot dip galvanized stainless steel air ducts, stainless steel plate stainless steel air ducts and composite stainless steel air ducts. Among them, the quality of stainless steel duct is good, the scope of application is strong, but the price is high. Nowadays, the wider stainless steel air duct in large shopping malls is made of galvanized steel. Galvanized steel stainless steel air duct is based on the characteristics of stainless steel plate and stainless steel air duct, but the price relativity is two-thirds or even lower than that of stainless steel air duct. The compound stainless steel air duct is generally used in the site where the external natural environment is relatively general and the air duct regulations are not too high. Because the white iron sheet is very easy to produce chemical changes in a variety of natural environments, resulting in corrosion and corrosion.
However, zinc hardly changes in dry air. In the humid and cold air, fine basic zinc carbonate film will be formed on the surface of zinc. The key of stainless steel air duct is to insert a layer of zinc on the white iron sheet of the air duct, which has the actual effect of maintenance. After passivating, coloring or applying light protecting agent on stainless steel, zinc coating can obviously develop its protection and decorative art.
