Galvanized rectangular tubes are hollow square-section steel tubes with a square cross-section and specific dimensions. They are manufactured by cold bending and high-frequency welding of hot-rolled or cold-rolled galvanized steel strips or galvanized steel coils. Alternatively, they can be made by hot-dip galvanizing pre-made cold-bent hollow steel tubes.
