Torque tube

   A rectangular tube is a rectangular tube. Rectangular tube is a kind of hollow long steel, also known as flat tube, flat square tube or square flat tube (as the name implies). When the bending and torsion strength are the same, the weight is lighter, so it is widely used in manufacturing mechanical parts and engineering structures.
   There are two main production modes of rectangular tube, i. e. cold rolling and hot rolling. Hot rolling of rectangular tube is made by coiling hot rolled strip after processing. Cold-drawn or cold-rolled precise rectangular tubes are cold-drawn or cold-rolled precise rectangular tubes used for mechanical structures, hydraulic equipment with high dimensional accuracy and good surface finish.
