Purlin

A purlin (or historically purline, purloyne, purling, perling) is a longitudinal, horizontal, structural member in a roof. In traditional timber framing there are three basic types of purlin: purlin plate, principal purlin, and common purlin.

Not to be confused with Perlin (disambiguation).

Purlins also appear in steel frame construction. Steel purlins may be painted or greased for protection from the environment.
