Many people are not familiar with spiral duct machines. At present, the spiral duct market is generally divided into three categories according to materials: galvanized spiral duct, stainless steel spiral duct and composite spiral duct. Among them, the stainless steel duct has the best quality and strong applicability, but the price is high. The spiral ducts that are currently the most widely distributed on the market are galvanized sheets. Galvanized sheet spiral ducts are basically the characteristics of stainless steel spiral ducts, but the price is relatively only two-thirds or even lower than that of stainless steel ducts.
Air duct machine
According to the structure and environment of the place where the ventilation ducts are to be installed, the ventilation ducts shall be designed to ensure the practicability of the ventilation ducts. Generally, the ventilation ducts of the air supply system and the air conditioning system are installed, and the installation is completed on the roof of the building, and the obstacles at the installation site are cleaned.
The spiral duct has a stable structure, in addition to its high strength from the material point of view, but also because the material of the duct is very rigid. In this way, under the promotion of the material, the structure of the air duct is not easily damaged by external force, and the structure can be reliably ensured during use, and the spiral duct can always function reliably when the structure is not prone to problems.
