PURLIN

A purlin is a horizontal structural member used in roof construction that supports the rafters or roofing sheets and helps distribute the roof load to the main building frame. It is typically placed parallel to the ridge of the roof and is supported by rafters, trusses, or beams depending on the structure. Purlins are commonly made of wood, steel, or sometimes reinforced materials in modern construction. They increase the strength and stability of the roof by reducing the span of rafters and preventing sagging of roofing sheets. Purlins are widely used in industrial sheds, warehouses, and residential roofing systems.
