* The minimum bending radius mentioned here is only a theoretical value, not the actual bending radius achievable in roll bending. Since different manufacturers' profile bending machines have rollers with varying diameters, the minimum bending radius that can be achieved for flat steel profiles of the same dimensions will also differ across different profile bending machines.
In actual production, process verification needs to be carried out according to equipment parameters and material properties.
* Material yield strength: 245MPa | Width/thickness ratio: 5:1
* Weak axis thickness limit: 100mm
