4. Annealing Following the cold rolling process, the steel strips may require annealing. This heat treatment process relieves internal stresses that develop during cold rolling, restoring ductility and reducing hardness. The annealing process can be performed in a continuous furnace where the steel strip is heated and then gradually cooled.
3. Customization Different construction projects often require purlins of varying sizes and shapes. Purlin roll forming machines offer customization options, allowing manufacturers to produce purlins according to specific design requirements. This adaptability is a significant advantage, as it meets the diverse needs of different architectural styles.
