The purlin is the framing member the roofing sheets screw to.
A purlin is a structural part of a roof which is used to support rafters and carry the roof cladding By supporting the rafters they allow for longer roof spans to be created allowing for wider buildings to be created.
Most sloped roofs are supported by a purlin bracing system. A board the same size as or larger than that of the rafters is placed on edge perpendicular to the rafters and attached on the bottom side of the rafters. Legs are then placed under the purlin brace and with the top notched under the purlin and the bottom placed on and attached to the top of a wall, thus transferring the weight of the roof from the rafters to the top of the walls.
it is when two spanning members (usually a beam or a purlin or rafter) come together to form a butt joint.
