Automatic spiral duct machines are generally divided into three categories according to their materials in the market: galvanized spiral ducts, stainless steel spiral ducts and composite spiral ducts. In order to achieve the goal of energy saving and environmental protection of automatic spiral duct equipment, various enterprises have carried out related activities around the theme of energy saving and environmental protection. Fully automatic spiral duct machines have increased in new product development, product design, manufacturing technology, and production line technical transformation, and a large investment has been made to promote equipment upgrades.

The spiral duct machine is a machine that produces spiral ducts. Spiral duct machines, also known as spiral slit thin-walled ducts, were early used in Western military industry, such as warships, platoon (transmission) air systems, etc., and later used in civilian facilities such as trains, subways, and mines. The system can handle stainless steel, galvanized steel, aluminum and copper plates, automatic coiling equipment, automatic installation of measuring equipment, automatic digital system can produce a variety of different pipes. Many people are not familiar with spiral duct machines. At present, the spiral duct market is generally divided into three categories according to material: galvanized spiral duct, stainless steel spiral duct and composite spiral duct. Among them, the stainless steel duct is of good quality and strong applicability, but the price is high. At present, the spiral air duct widely circulated in the market uses galvanized sheet. Galvanized spiral duct is basically the characteristic of stainless steel spiral duct.

However, the price is only two-thirds or lower than that of stainless steel ducts. According to the structure and environment of the place where the ventilation ducts need to be installed, the ventilation duct design is carried out to ensure the practicability of the ventilation ducts. Generally, the installation of ventilation ducts for air supply and exhaust systems and air conditioning systems must be carried out on the roof of the building, and the obstacles at the installation site have been cleared. The spiral duct machine has a stable structure, not only because of its high strength in material, but also because the material of this duct is very hard. In this way, driven by the material, the spiral duct machine has a structure that is not easily damaged by external forces, and can be reliable and stable in use. When the structure is not prone to problems, the spiral duct can always operate reliably.
