HSS - CSA G40 Rectangular (HS) - HS305x203x7.9

Rectangular Hollow Structural Sections to CSA G40.21 are the Canadian-grade counterpart to ASTM A500 rectangular HSS, and are widely specified across Canada for columns, truss chords, canopy and mezzanine framing, and any application needing a torsionally stiff member with flat faces for easy connections. The rectangular profile is efficient where bending governs in one direction more than the other, letting the deeper dimension do the work. Every section in this CSA G40 rectangular family is available as a free CAD block, with full dimensional and property data from CISC 12.
