Galvanized welded duct, as the name suggests, is a ventilation duct made of steel that has been galvanized and then connected through welding process. It usually has a rectangular or circular cross-section and can be customized to different sizes and specifications as needed. Galvanized layer can effectively prevent steel from rusting and extend the service life of air ducts.

Strong corrosion resistance: The galvanized layer effectively prevents rusting of the iron sheet through the sacrificial anode protection principle, making it suitable for corrosive environments such as humidity, acidity, and alkalinity. Galvanized welded air ducts can be used for a long time in harsh environments without rusting, thereby reducing maintenance costs.
Good wear resistance: During transportation and installation, air ducts are prone to wear and tear. Galvanized welded air ducts have strong wear resistance and can maintain their intact state for a long time, extending the service life of the ducts.
Good high temperature resistance: Galvanized welded air ducts can withstand high temperatures and are not easily deformed or aged. This characteristic makes it applicable in high-temperature environments, such as ovens, chimneys, and other places.
Good sealing performance: The welding process ensures strong sealing at the connection of galvanized welded air ducts, reducing air leakage and improving the operational efficiency of the system.
High strength and not easily deformed: Galvanized steel plates have good mechanical strength, can withstand wind pressure and resistance, and are not easily deformed. This ensures the stability and reliability of the air duct during long-term use.
High construction efficiency: Galvanized welded air ducts can be adjusted in length and angle according to actual needs to adapt to different usage environments. At the same time, its installation and maintenance are also very convenient, with high construction efficiency and short construction period.

Galvanized welded air ducts are used in ventilation, exhaust, air conditioning and other systems in the fields of construction, industry, ships, etc. For example, in factory workshops, warehouses, shopping malls, office buildings, and other places, galvanized welded air ducts are used to transport fresh air, remove exhaust gases or odors; On ships, it is used for ventilation and air exchange in the cabin.

The manufacturing process of galvanized welded air ducts includes multiple steps such as material preparation, cutting, bending, welding, and anti-corrosion treatment. In the production process, it is necessary to strictly control the quality of each link to ensure the performance and quality of the product. For example, in the welding process, it is necessary to choose appropriate welding methods and parameters to ensure the quality and strength of the weld seam; In the process of anti-corrosion treatment, it is necessary to choose appropriate anti-corrosion coatings and coating processes to improve the anti-corrosion performance of air ducts.
