What Are Purlins and Girts? Key Structural Components in Metal Buildings
Learn what purlins and girts are and how they provide essential support in metal building construction.
117 views
Purlins and girts are structural components used in metal buildings and pole barns. Purlins are horizontal beams that are laid across the trusses to support the roof deck or sheathing. They effectively spread the load of the roofing materials. On the other hand, girts serve a similar function but are installed vertically on the walls to provide lateral support for the wall cladding. Both are essential for providing structural integrity and support to the building's framework.
