Abstract
An extruded profile defining a normal section surface, a horizontal loading direction along the normal section surface and a vertical loading direction along the normal section surface perpendicular to the horizontal loading direction The profile includes a core arranged in a central position at the intersection of the directions, a plurality of arms each including a radial segment radially connected to the core and a tangential segment perpendicularly connected to the radial segment The radial segments of the adjacent arms are perpendicular to each other and each oriented 45° to the horizontal load direction and/or the vertical load direction, and the tangential segments of the adjacent arms are configured to simultaneously support the same load along the horizontal load direction and/or the vertical load direction.
