Supplementary HSS Tables

The tables on the following pages provide detailing dimensions and engineering properties of larger-

size Hollow Structural Sections (HSS) produced by Copperweld Canada but not included in the CISC

Handbook of Steel Construction, 8thEdition, 2004.

Steel Grades

The rectangular and square HSS included in the tables are produced by Copperweld Canada in the

following steel grades: CSA G40.20/G40.21-350W and ASTM A500. All shapes listed are generally

available in both G40.20 and A500, except for those with a nominal wall thickness of 16 mm, which

are only available in A500.

For further information on HSS steel grades, contact:

Dimensions and Properties

Section dimensions and properties of HSS produced to CSA G40.20 are based on the nominal wall

thickness. This is the thickness which, when rounded, forms the third term of the section designation.

With the exception of the mass and dead load, dimensions and properties of HSS produced to ASTM

A500 are based on the design wall thickness, taken equal to 0.90 times the nominal wall thickness.

Design information

General information on the design and material properties of HSS may be found in the CISC

Handbook of Steel Construction and in Hollow Structural Sections: Connections and Trusses -

A Design Guide, by Packer and Henderson. Further information may be found on the CISC website:www.cisc-icca.ca
