The outer rounding radius ro and the inner rounding radius ri are specified as nominal values to be used in calculations in the standards and they are specified in the design standards EN 10210-2 §A.3 for hot finished structural hollow sections and EN 10219-2 §B.3 for cold formed structural hollow sections: For any thickness: ro = 1.5t and ri = 1.0t, For thickness t ≤ 6 mm: ro = 2.0t and ri = 1.0t, For thickness 6 mm > t ≤ 10 mm: ro = 2.5t and ri = 1.5t, For thickness t > 10 mm: ro = 3.0t and ri = 2.0t. x$v�2��0K/�A��3%ͥ���>n����YЈ�&���d���1�qF#�q=h�ɷJ'�4�C����-���l����s�ܱ&"�R>��$���A���R��*�`��`9s�&���V�p�ա�^�`58Σ�b��*KV\�yǮl�9�c�K�X�G$e�\N�BʆE|/7������s������g2�G�h���̤�L�V�=fgJLzM�,�1E�;܋�Ќ�HP�ǂ��VPi���V�#��[i�'U����p?1Ι�������D ��}Hcp�n�\�`�E��k��.����\ ��M#�eW�f���$��i�68ӡU(.
