[0002] Square tube is a name for square tube and rectangular tube, that is, steel tube with equal and unequal side lengths. It is made by rolling steel strips through process processing. Generally, the steel strips are unpacked, flattened, curled, and welded to form round tubes, which are then rolled into square tubes and cut into required lengths. Now, square tubes need to be hot-dip galvanized after production and processing.

Before putting the square rectangular tube into the galvanizing tank, the square rectangular tube needs to be dried. In the process of drying the square rectangular tube, not only a lot of time will be consumed, but also the galvanizing efficiency of the square rectangular tube will be reduced. In addition, it is difficult to completely dry the square rectangular tube by this method, which affects the galvanizing quality of the square rectangular tube. Utility Model Content
