In steel construction, the term purlin typically refers to roof framing members that span parallel to the building eave,^[5] and support the roof decking or sheeting. The purlins are in turn supported by rafters or walls. Purlins are most commonly used in Steel Framed Building Systems, where Z-shapes are utilized in a manner that allows flexural continuity between spans.

Z Purlins are extremely strong and can support heavy structures although, C purlins have relatively less strength. Therefore, in buildings with a bigger roofing or loading capacity, Z purlins would be a better choice. They are commonly used in agricultural and industrial buildings.
