散裝物料的輸送。在一些通風管道加工工廠的生產過程中，需要輸送松散的顆粒，特別是比例較小的螺旋風管，如發泡塑料顆粒，成本低，效果好。螺旋風管是一種薄壁管，由金屬帶材卷制而成，圓形，無焊接，無漏氣，無漏水，多用于送風和散裝物料輸送，而不是傳統的白鐵管(即手工咬鐵管)。它是一種風管，全機制，直管不需要手動敲擊。

Transportation of bulk materials. In the production process of some air duct processing plants, it is necessary to transport loose particles, especially spiral air ducts with small proportion, such as foamed plastic particles, which have low cost and good effect. Spiral air duct is a kind of thin-walled pipe, which is rolled from metal strip, round, without welding, air leakage and water leakage. It is mainly used for air supply and bulk material transportation, rather than traditional white iron pipe (i.e. manual iron biting pipe). It is an air duct with full mechanism, and the straight pipe does not need to be manually knocked.

鍍鋅螺旋風管指酒店、、紡織、化纖、石油化工、機械制造、儀表、電子、醫藥、煙草、食品、倉儲、寫字樓及地鐵、人防、地下室等工程的送風、排風、排煙管道。它的厚度和規格可根據需要而變化，通常在連接時，鍍鋅螺旋風管的兩端都要外接。

Galvanized spiral air duct refers to the air supply, exhaust and smoke exhaust ducts for hotels, shopping malls, textiles, chemical fiber, petrochemical industry, machinery manufacturing, instruments, electronics, medicine, tobacco, food, storage, office buildings, subway, civil air defense, basement and other projects. Its thickness and specification can vary according to needs. Generally, both ends of the galvanized spiral air duct shall be externally connected when connecting.

由于鐵皮加工在不同環境下容易發生反應，導致腐蝕和生銹。鋅在干燥的空氣中基本沒有變化。在潮濕的空氣中，鋅表面會產生致密的堿性碳酸鋅膜，因此在風管鐵皮上鍍一層鋅可以保護鐵皮。鍍鋅處理鈍化、染色或涂上護光劑后，可加強其保護性和裝飾性。

As iron sheet processing is easy to react in different environments, corrosion and rust are caused. Zinc has little change in dry air. In humid air, the zinc surface will produce a dense alkaline zinc carbonate film, so a layer of zinc on the iron sheet of the air duct can protect the iron sheet. The protection and decoration can be enhanced after passivation, dyeing or coating of light protecting agent by galvanizing treatment.
