HSS Corner Radius 4

[Rocks1]

Does anyone have a chart listing corner radius's for HHS rectangular tube steel?

Check your AISC manual (assuming USA) - pretty sure it’s 2 times the wall thickness as an estimated radius but does vary.

JAE is in the ball park. See quote below.

The corner radius of Hollow Structural Sections (HSS) is not something that can be manipulated to order, and is part of the existing manufacturing paradigm of numerous HSS producers in North America. The typical outside corner radius of North American HSS is 2t, where t is the wall thickness of the as-produced HSS, to the standard ASTM A500-10.

AISC 360-16 Section B4.1b.(d) specifies that for local buckling of HSS members, 'b' and 'h' shall be taken as the outside dimension minus 3t, if the corner radius is not known. That implies an outside corner radius equal to 1.5t, where 't' is the design wall thickness.
