A galvanized square pipe refers to a hollow steel pipe with a square cross-sectional shape and size. It is produced using hot-rolled or cold-rolled galvanized strip or galvanized coil as the raw material. The manufacturing process involves cold forming and high-frequency welding. Afterward, the square pipe undergoes hot-dip galvanization, where it is immersed in a bath of molten zinc to create a protective coating.

The galvanized square pipe, also known as a galvanized rectangular pipe if processed into a rectangular shape, offers several advantages. The galvanized coating provides excellent corrosion resistance, protecting the underlying steel from rust and extending the pipe's lifespan. Furthermore, the square shape of the pipe makes it well-suited for various applications, including structural support, construction, and fabrication projects.
