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.
Note: Use dot "." as decimal separator.
Note *:The design wall thickness t, shall be used in calculations involving the wall thickness of hollow structural sections (HSS) per Steel Construction Manual Section B3.12.
