Purlins is a horizontal beam along the length of a roof, resting on principals and supporting the common rafters or boards. It is made of steel and is used as a member of roof structure.
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. They are in turn supported by rafters or walls. This product is most commonly used in Metal Building Systems, where Z-shapes are utilized in a manner that allows flexural continuity between spans.
