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.

雖然如今核心的仍是白鐵皮這一類的風管，但由于這種風管環境保護、壽限、防水、隔音降噪、載重等各層面緣故，在工程施工和維護上存有很多的缺點。這就造成了大型必須一種新的商品來改進這一難點，新型不銹鋼風管的展現，恰好習慣大型的要求，在根據許多工程項目應用及實踐經驗后，逐漸的被投資人房地產商所承擔。

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 has caused the large-scale shopping malls to have a new commodity to improve this difficulty. The display of new stainless steel air duct is just used to the requirements of large-scale shopping malls. According to the application and practical experience of many engineering projects, it is gradually undertaken by investors and real estate developers.

風管大型上按材料一般分成三類：熱鍍鋅不銹鋼風管、不銹鋼板不銹鋼風管及其復合型不銹鋼風管。在其中，不銹鋼風管品質不錯，適用范圍強，但價錢高。如今大型上較廣的不銹鋼風管是鍍鋅鋼板的。鍍鋅鋼板不銹鋼風管，基礎是不銹鋼板不銹鋼風管的特點，但是價錢相對性要是不銹鋼風管的三分之二甚更低。

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.

復合型不銹鋼風管一般應用在外部自然環境比較一般，對風管規定不太高的場地。由于白鐵皮非常容易在各種各樣自然環境下產生化學變化，導致浸蝕、銹蝕。

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, the zinc content in the dry air is almost unchanged. 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.

通風管道由隔熱層兩面復合型防護層制做而成，隔熱層又關鍵分成泡沫塑料和玻璃纖維棉兩類。山東省通風管道多見的風管板為鋁鉑復合型酚醛泡沫板、鋁鉑復合型發泡聚氨酯板、鋁鉑復合型阻燃塑料聚乙烯保溫泡沫板、隔熱保溫玻璃纖維棉風管板等。這類風管在應用特性上相對性理想，傳熱系數小、質輕、易工程施工、清潔等，當今以前應用在很多大家民用型機器設備中，包括高層住宅機器設備內。

The ventilation pipe is made of two layers of thermal insulation layer, and the insulation layer is divided into two categories: foam plastic and glass fiber cotton. The air duct plates commonly seen in Shandong's ventilation ducts are aluminum and platinum composite phenolic foam board, aluminum platinum composite foam polyurethane board, aluminum platinum composite flame retardant plastic polyethylene insulation foam board, thermal insulation glass fiber cotton wind pipe plate and so on. This kind of air duct has ideal relativity in application characteristics, small heat transfer coefficient, light weight, easy engineering construction, cleaning, etc. it was used in many civil machinery and equipment, including high-rise residential machinery and equipment.
