| 螺旋风管市场上按材质一般分为三类：镀锌螺旋风管、不锈钢螺旋风管以及复合螺旋风管。其中，不锈钢风管质量最好，适用性强，但价格高。目前市场上流通最广的螺旋风管是镀锌 板的。镀锌板螺旋风管，基本是不锈钢螺旋风管的特性，但是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通，对风管要求不太高的场所。 The spiral duct market is divided into three types: galvanized spiral duct, stainless steel spiral duct and composite spiral duct. The stainless steel duct has the best quality and good applicability, but the price is high. The most widely circulated spiral duct in the market is galvanized sheet. Galvanized sheet spiral duct, which is basically stainless steel spiral duct, but the price is only two thirds or even lower than the stainless steel duct. Composite spiral duct is generally used in the external environment more ordinary, to the air pipe requirements not too high place. |
