Product Description

Square tubes is a form of tube type, people have a different name on it, called the rectangular tubes, rectangular tubes, square tubes, welded square tube, because it has a lot of kinds of material of material can make the tube body, usually square tube is formed after unpacking, kaiping, bending strip welding pipe, again by the mechanism of rolling into a square tube.

It is made of strip steel that has been processed and rolled. Generally, the strip is unpacked, flattened, coiled, welded to form a round tube, and then rolled into a square tube from the round tube and then cut to the required length. Square rectangular tube is also called cold-formed hollow section steel, referred to as square tube and rectangular tube.
