HSS - CSA G40 Round (HS) - HS102x6.4

Round Hollow Structural Sections to CSA G40.21 are the Canadian-grade circular HSS family, used throughout Canada for columns, bracing, handrails, and any structure where equal strength in all directions and a clean circular profile are wanted. Their closed shape gives efficient resistance to buckling for a given weight of steel, and the round profile is a common architectural choice for exposed steelwork. The full CSA G40 round range is available here as free CAD blocks, with outside diameter and wall thickness data from CISC 12.
