Thin-wall curled Z-shaped steel

Z-shaped steel is a common cold-formed thin-walled steel. The thickness is usually 1.6-3.0mm, and the cross-sectional height is mostly 120-300mm. Processing materials are hot-rolled (painted) and galvanized. It is generally called C purlins as simple purlins and Z purlins as continuous purlins. The two are realized by different overlapping methods. Simple supported purlins do not require overlapping lengths, and Z-shaped steel is usually used in large steel structure workshops.
