Ductwork can be categorized by cross-section, including rectangular ducts, circular ducts, spiral ducts, and so on. Galvanized steel rectangular ducts are a type of ductwork, made from galvanized steel material, serving as exhaust equipment. They are widely used, predominantly in industrial buildings. Next, the editor from a Chongqing ductwork manufacturer will share the features and applications of galvanized steel rectangular ducts.
Ductwork is typically installed indoors, with rectangular ducts usually placed within the ceiling to minimize the impact on the net room height. These are generally designed as tall and narrow to wide. If installed outdoors in areas where space is not a concern, circular ducts are recommended to reduce ventilation resistance and material usage.
Rectangular ductwork refers to hollow metal profiles with a rectangular or square cross-section. It is easier to process, has convenient branching connections, and is suitable for spatial orientation layout. The bottom seams are fewer, making it less likely to leak water, and it is convenient for insulation work with low technical difficulty in construction. The ease of processing and manufacturing of rectangular ventilation ducts is one of the reasons why they are more widely used than circular ducts. Rectangular ductwork is applied in industries such as construction, machinery manufacturing, shipbuilding, hardware, and steel structure engineering.
The cross-section of air conditioning ducts is generally rectangular, with supply and return air ducts often using rectangular ducts. The materials are typically galvanized steel sheet and composite materials. Rectangular ventilation ducts have a series of standard side lengths and specified ratios of the two side lengths, such as 120, 250, 320, 400, 500, 630, 800, 1000, 1250, and 2500, which is conducive to the cutting of galvanized steel sheet, eliminating waste and improving the utilization rate of the material.
