SQUARE STEEL HOLLOW SECTION is a term for square pipe and rectangular pipe, that is, steel pipes with equal and unequal side lengths. It is made of rolled strip steel after process treatment. Generally, the strip steel is unpacked, leveled, crimped, welded to form a round pipe, then rolled into a square pipe from the round pipe and then cut into the required length.
