Structural hollow sections. The usual process of manufacture is to form hot or cold-rolled steel strip to a circular shape then to join the abutting edges by an electric resistance weld (ERW) or submerged arc weld before final forming to the design shapes, usually circular hollow sections (CHS), square hollow sections (SHS) or rectangular hollow sections (RHS). Other geometric properties used in design include area for tension and shear, radius of gyration for compression, and moment of inertia and polar moment of inertia for stiffness. Section modulus is a geometric property for a given cross-section used in the design of beams or flexural members. The classification of cross-sections is specified in EN1993-1-1 §5.5.
