RECTANGULAR STEEL TUBING SIZES AND PROPERTIES

Rectangular steel tubing sizes, dimensions and section properties including moment of inertia, elastic section modulus, radius of gyration, torsional moment of inertia and plastic section modulus.

Rectangular steel tube has a rectangular hollow cross section except for rounded corners. Rectangular steel tubes are designated by "HSS", overall outside dimension (in.), and wall thickness. HSS10x8x5/8 is nominally 10 in. by 8 in. with a 5/8 in. wall thickness.
