Galvanized square tubes are divided into hot-dipped and cold-dipped types based on their production processes. Due to the differing processing methods of these two types of galvanized square tubes, they possess many distinct physical and chemical properties. In summary, they have significant differences in terms of strength, toughness, and mechanical properties.

Hot-Dip Galvanized Square Pipe: This is a square tube manufactured by welding steel plates or steel strips that have been curled into shape. On this basis, the square tube is then placed in a hot-dip galvanizing bath where it undergoes a series of chemical reactions to form the final product. The production process for hot-dip galvanized square tubes is relatively simple, with high production efficiency, a wide variety of specifications, and requires minimal equipment and capital, making it suitable for small-scale hot-dip galvanized square tube manufacturers. However, in terms of strength, these steel tubes are significantly lower than seamless square tubes.
