Square steel tubing usually divided as welded square steel tube and seamless square steel tube. When we say square steel tube which always means welded square hollow sections which outer diameter is smaller than seamless hollow sections but the price is much lower. Square steel tube is mainly used in construction as structure. The main steel grades are S355JR S275JRH S355JRH S355J0H and A500 square steel tubes. The usage of square steel tube provides for strong, light and profitable structures and as a result offer a host of possibilities in terms of application.

Square steel tube, as the name implies, it is a kind of form of tube type. There is a lot of kinds of material of material can make the square tube after unpacking, smooth, curly, form circular tube welding, again by circular tube rolling into square tube and then cut into required length. Every package is generally 50 square steel tube on the side of the spot in the majority with large size 10*10*0.8-1.5~~500*500*10-25mm. Square tube is divided into square tube structure, according to the use decorative tube, architects, mechanical square tube etc. Square steel tube is a kind of square steel tubes, also is the equal of the steel tube length. I s the strip steel rolled through the process. Square steel tubing is a hollow square cross section light thin wall steel tube, also known as refrigeration bending steel profiles. It is hot or cold rolled steel strip or rolled plate for the parent metal by cold bending forming by high frequency welding again after made of square cross section shape, the size of the steel. Hot rolled, thick-walled square tube in addition to outside in the thickness of the wall thickness, the size and edge Angle straightness achieves even exceed the level of the resistance welding cold forming square tube. Good comprehensive mechanical performance, weld ability, cold and hot working performance and corrosion resistance are good, good low temperature toughness.
