Rectangular steel tubing
Rectangular tube is a light-weight thin-walled steel tube with rectangular section, also known as steel cold-formed profile. It is a section steel with square section shape and size made of Q235 hot-rolled or cold-rolled strip or coil as the base material, cold bending and high-frequency welding.   When the bending and torsional strength are the same, the weight is light, so it is widely used to manufacture mechanical parts and engineering structures.
