# SQUARE HOLLOW SECTION PROPERTIES CALCULATOR

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.
