Galvanized square tube is divided into two production processes based on the manufacturing processHot dip galvanized square tube and cold dip galvanized square tubeIt is precisely because the processing of these two types of galvanized square tubes is different that they have many different physical and chemical properties. Overall, they have many differences in strength, toughness, and mechanical properties.Hot dip galvanized square tube: It is a type of square tube made by welding rolled steel plates or strips, and then placing the square tube in a hot-dip galvanizing tank through a series of chemical reactions on the basis of this square tube. The production process of hot-dip galvanized square tube is relatively simple, with high production efficiency and a wide variety of specifications. This type of square tube requires very little equipment and funding, making it suitable for small-scale galvanized square tube manufacturers. However, in terms of strength, the strength of this steel pipe is much lower than that of seamless square pipes.
