Square hollow section properties, sizes and dimensions calculator .
Square HSS have an square cross section except for rounded corners. Square HSS are designated by "HSS", overall outside dimension (in.), and wall thickness.
HSS5x5x1/2 is nominally 5 in. by 5 in. with a 1/2 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.
