Galvanized square tubes are hollow square section steel pipes with square cross-section shapes and sizes, manufactured from hot-rolled or cold-rolled galvanized strip or coil, cold-bent into shape, and then high-frequency welded. Alternatively, pre-fabricated cold-bent hollow section steel pipes can be heat dipped in galvanizing process to produce galvanized square tubes.

Hot-Dip Galvanized Square Pipe: It is a square pipe made by welding steel plates or steel strip after rolling and forming, and then placed in a hot-dip galvanizing bath for a series of chemical reactions to form a new type of square pipe. The production process of hot-dip galvanized square pipe is relatively simple, with high production efficiency, a variety of specifications, and requires minimal equipment and capital, making it suitable for small-scale galvanized square pipe manufacturers.
