HSS - ASTM A500 Round (HA) - HA245x6.4

Round Hollow Structural Sections to ASTM A500 are circular tube profiles prized for their equal strength in every direction and their clean, architectural appearance — common in exposed columns, handrails and balustrades, bollards, and diagonal bracing where a compact, uniform member is wanted. Their closed circular shape gives excellent resistance to buckling and torsion for their weight, and their round profile sheds water and debris naturally in exterior applications. The full ASTM A500 round range is available here as free CAD blocks, with outside diameter and wall thickness data drawn from CISC 12.
