* In this survey we have tried to be as complete as possible. However, because our trade discipline is rather comprehensive, we couldn’t include all available section bending possibilities. Should you have any remaining queries, please contact us.

The values used in this overview are indications, assuming the material has a yield point of 270 N/mm2. Extra length depends on the over length.
