a Rectangular tube is a hollow long steel material, also known as flat tube, flat square tube or square flat tube (as the name implies). They are widely used as pipelines for transporting fluids, such as oil, natural gas, water, gas, steam, etc. In addition, they are lighter in weight when the bending and torsional strength are the same, so they are also widely used in the manufacture of mechanical parts and engineering structures.

b Rectangular tube is a hollow square cross-section lightweight thin-walled steel tube, also known as steel cold-formed profile. It is a square section steel with a square cross-section shape and size made of Q235 hot-rolled or cold-rolled strip or coil as the base material, cold bending and then high-frequency welding. In addition to the thickening of the wall thickness, the corner dimensions and edge straightness of hot-rolled extra-thick-walled square tubes reach or even exceed the level of resistance welded cold-formed square tubes.
