Brief introduction of spiral duct
Spiral duct on the market by the material is generally divided into three categories: spiral duct, stainless steel spiral duct and composite spiral duct. Among them, the best quality stainless steel duct, applicability, but the price is high. The most widely circulated spiral ducts on the market today are galvanized sheets. Spiral ducts, basically have the characteristics of stainless steel spiral duct, but the price is only two-thirds or less of stainless steel ducts. Composite spiral duct is generally used in the external environment is more common, the requirements of the duct is not too high.
As the metal easily in a variety of environments, chemical reactions, resulting in corrosion, rust. And zinc in the dry air almost no change. In the damp air, zinc surface will produce dense alkaline zinc carbonate film. Spiral ducts are mainly coated with a layer of zinc on the duct, which plays a protective role. Zinc coating by passivation treatment, dyeing or coating protective agent, can significantly improve its protective and decorative. Xiaobian will be on the ventilation system commonly used in the spiral duct for some introduction.
