| 不锈钢风管质量最好，适用性强，但价格高。目前市场用于通风排气工程使用广泛的螺旋风管是镀锌板制作的。即镀锌螺旋风管，虽然它不及不锈钢螺旋风管的特性，但是它的价格相对只有不锈钢风管的三分之二甚至更低。复合螺旋风管一般应用在外界环境较为普保定平面设计培训 保定室内设计培训 保定空调移机 保定太阳能维修 保定厨房排烟 雄安管道通风 通，对风管要求不太高的场所使用。 Stainless steel air duct has the best quality, strong applicability, but high price. At present, the spiral air duct widely used in ventilation and exhaust engineering is made of galvanized sheet. That is, galvanized spiral air duct, although it is not as good as the characteristics of stainless steel spiral air duct, but its price is only two-thirds or even lower than that of stainless steel air duct. The composite spiral air duct is generally used in the places where the external environment is relatively common and the air duct requirements are not too high |
