    Square rectangular pipe is a term for square and rectangular pipes, which refers to steel pipes with equal or unequal side lengths. It is rolled from strip steel through process processing. Generally, the strip steel is unpacked, flattened, curled, and welded into circular tubes, which are then rolled into square tubes and cut to the required length.
