SQUARE HOLLOW SECTIONS (SHS)

CR, HR and GP Square HSS is referenced as hollow structural steel. The three basic shapes are referenced as CHS, SHS, and RHS, being circular, square, and rectangular hollow sections. Circular HSS are sometimes mistakenly called steel pipe, although true steel pipe is actually dimensioned and classed differently from HSS. (HSS dimensions are based on exterior dimensions of the profile pipes are also manufactured to an exterior tolerance, albeit to a different standard.) The corners of HSS are heavily rounded, having a radius which is approximately twice the wall thickness. The wall thickness is uniform around the section.
