HSS - ASTM A500 Square (HA) - HA178x178x6.4

Square Hollow Structural Sections to ASTM A500 combine the torsional stiffness of a closed tube with equal bending resistance about both axes, making them a go-to choice for columns, truss members, and any application where loads may come from more than one direction. Their flat, symmetrical faces simplify connection design and make them a favourite for exposed architectural steelwork as well as everyday structural framing. This family covers the full ASTM A500 square range as free CAD blocks, with outside dimensions, wall thickness and corner radii drawn from CISC 12.
