Square Steel Tube is a metal that has been formed into a square tube. It is measured by taking the outside dimensions (which are the same size) and then the wall thickness. It is easy to weld, shape, cut and related process, meanwhile it can be processed galvanized coating which is better corrosion resistance and anti rust than other types of steel.
Square steel tube can be used in conduction and structures, such as road signs, towing lathes, supporting skycrapers and bridges.Its strengths are high cost performance, high intensity and uniformity.
