Specification

Square tubing is a kind of shaped steel tube that is slotted and bent on a steel plate and then welded into it. The steel square tube has a square cross-section and has the advantages of clear corners, precise dimensions, smooth surface, and corrosion resistance. It is widely used in construction, machinery manufacturing, furniture manufacturing, billboard production and other fields.


Rectangular tube is a shaped steel tube similar to square tube, but its cross-sectional shape is rectangular. Rectangular tubes are cut into shape from steel plates and then made through welding or seamless manufacturing processes. Rectangular pipes have the characteristics of light weight, high strength, no deformation, and corrosion resistance. They are one of the important materials in construction, bridges, machinery manufacturing, solar brackets and other industries.
