Rectangular pipe is a kind of hollow pipe with square or rectangular cross-section. It belongs to a kind of steel pipe, mostly with small caliber.
When the bending and torsional strength are the same, the weight is lighter, so it is widely used in manufacturing mechanical parts and engineering structures.
