Rectangular/Square tube is a hollow square cross-section lightweight thin-walled steel tube, also known as steel cooling bending profiles. It uses Q235 hot-rolled or cold-rolled steel strip or coil as the base material through a cold bending process followed by high-frequency welding. Hot rolled extra thick walled square tubes offer superior corner dimensions and edge straightness.
Classification: Includes seamless steel pipe and welded steel pipe (seamed pipe), further categorized into hot-rolled, cold-drawn, and extruded seamless square tubes.
