These C-section purlins are formed through the continuous cold-roll forming of hot-rolled steel strips using fully automated machinery. They feature a standard C-shaped cross-section and are classified as lightweight, thin-walled structural profiles. Produced without the need for hot processing, they offer precise dimensions and an optimized cross-sectional shape. They are widely used as load-bearing and structural support components—such as wall purlins, roof purlins, brackets, columns, and secondary beams—in steel-structured buildings.
