People would rather decorate their house with beautiful material, produced by steel roll forming machine, named color steel roof. As above picture showing, white wall panel with brown roof of classical combination is imitated by many designers. But there’ re also some details about this type of machine which need us to understand.
When steel roll forming machine bending a piece of sheet metal, the residual stress in the material will cause the sheet to spring back slightly after the bending operation. Due to this elastic recovery, it’s necessary to over-bend the sheet a precise a amount to achieve the desired bend radius and bend angle. The final bend radius will be greater than initially formed and the final bend angle will be smaller.
