Galvanized square tubes are categorized into hot-dip galvanized and cold-dip galvanized types based on their production processes. It is due to the differing processing methods of these two types of galvanized square tubes that they possess many distinct physical and chemical properties. Overall, they exhibit significant differences in terms of strength, toughness, and mechanical properties.

Hot-Dip Galvanized Square Tubes: These are square tubes produced by welding steel plates or steel strip coils into shape, followed by placing the tubes into a hot-dip galvanizing bath where they undergo a series of chemical reactions to form the final product. The production process for hot-dip galvanized square tubes is relatively simple, with high efficiency and a wide variety of sizes. The equipment and capital required for this type of tube are minimal, making it suitable for small-scale galvanized square tube manufacturers. However, in terms of strength, these tubes are significantly weaker than seamless square tubes.
