Square steel pipe is a name for a square pipe, which is a steel pipe with equal sides. It is made of rolled strip steel through a process.
Generally, the strip is unpacked, flattened, rolled and welded to form a round tube, which is then rolled into a square tube and cut to the required length.
There are seamless and welded square tubes. Seamless square tubes are formed by extruding seamless round tubes.
