尽管现在核心仍然是白铁皮这一类的风管，但由于这种风管环境保护、寿限、防水、隔音降噪、载重等诸多方面的原因，在工程施工和维护方面存在许多缺点。这种情况导致了大型需要一种新的商品来改善这一难题，新型的不锈钢风管展现出来，恰巧习惯了大型的需求，在根据许多工程项目应用及实践经验后，逐渐由投资人房地产商承担。

Although the core is still the air duct such as white iron sheet, there are many shortcomings in project construction and maintenance due to many reasons such as environmental protection, life limit, waterproof, sound insulation and noise reduction, load and so on. This situation leads to the need for a new commodity in large shopping malls to improve this problem. The new stainless steel air duct is displayed, which happens to be used to the needs of large shopping malls. After many engineering project applications and practical experience, it is gradually borne by investors and real estate developers.

在大型的风管上，根据材质一般分为三类：热镀锌不锈钢风管、不锈钢板不锈钢风管及复合不锈钢风管。它们中不锈钢风管质量好，适用范围广，但较高。

In large air duct shopping malls, they are generally divided into three categories according to the material: hot-dip galvanized stainless steel air duct, stainless steel plate stainless steel air duct and composite stainless steel air duct. Among them, stainless steel air ducts have good quality and wide application range, but the price is high.

现在大型中常用的不锈钢风管都是镀锌钢板。镀锌板不锈钢风管，基础是不锈钢板不锈钢风管的特点，但相对性要是不锈钢管的三分之二甚更低。复合式不锈钢风管一般应用于外界环境较一般、风管要求较低的场所。

Now the stainless steel air ducts commonly used in large shopping malls are galvanized steel. Galvanized stainless steel air duct is based on the characteristics of stainless steel air duct, but the price relativity is two-thirds or even lower than that of stainless steel pipe. Composite stainless steel air duct is generally used in places with general external environment and low air duct requirements.

因为白铁皮在各种自然环境中很容易发生化学变化，导致浸蚀、锈蚀。山东的通风管道和锌在干燥空气中几乎不产生变化。锌的表面层在湿冷的空气中形成了碱式碳酸锌薄膜。不锈钢管的关键是在风管白铁表面镶上一层锌，对白铁外壳起到了实际维护作用。锌镀层经过不锈钢钝化、涂色或涂覆等处理，可显著提高涂层的防护能力和装饰艺术。

Because the white iron sheet is prone to chemical changes in various natural environments, resulting in corrosion and corrosion. Ventilation ducts and zinc in Shandong hardly change in dry air. The surface layer of zinc forms a basic zinc carbonate film in wet and cold air. The key of stainless steel pipe is to inlay a layer of zinc on the white iron surface of air pipe, which plays a practical role in maintaining the white iron shell. After passivation, coloring or coating of stainless steel, the protective ability and decorative art of zinc coating can be significantly improved.

(1)通风管道输送气体无噪音，或兼有消音作用

(1) The gas conveyed by the ventilation pipe has no noise or has silencing effect

(2)通风管道在耐压允许标准下，风管内气体不易外泄，或气管外气不易内侵入

(2) Under the allowable pressure resistance standard of ventilation pipe, the gas in the air pipe is not easy to leak out, or the gas outside the gas pipe is not easy to invade

(3)通风管道应用期限短维修简便。

(3) The ventilation pipe has short application life and easy maintenance.
