Description

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

It
is the practice in the steel industry that structural shapes are assigned
representative designations for convenient shorthand description on drawings
and documentation: Channel sections, with or without flange stiffeners, are
usually referenced as C shapes; Channel sections without flange stiffeners are
also referenced as U shapes; Point symmetric sections that are shaped similar
to the letter Z are referenced as Z shapes. Section designations can be
regional and even specific to a manufacturer. In steel building construction,
secondary members such as purlins (roof) and grits (wall) are frequently  C, Z or U sections, (or mill rolled) C
sections.

Cold
formed members can be efficient on a weight basis relative to mill rolled
sections for secondary member applications. Additionally, Z sections can be
nested for transportation bundling and, on the building, lapped at the supports
to develop a structurally efficient continuous beam across multiple supports.
