HSS - ASTM A500 Rectangular (HA) - HA203x102x7.9

Rectangular Hollow Structural Sections to ASTM A500 are closed, cold-formed tube profiles used wherever a torsionally stiff, visually clean member is needed — exposed columns and canopy framing, truss chords, handrail and guard posts, and equipment supports. The closed section resists twisting far better than an open shape of similar weight, and the flat faces make welding gusset plates and connections straightforward. This family covers the full ASTM A500 rectangular range, from small architectural tube sizes up to heavy structural sections, each available as a free CAD block with complete dimensional and property data drawn from CISC 12.
