Secondary structural steel framing components are “cee” and “zee” shaped members. They are used on the roof to span the distance between the primary rigid framed rafters in order to support the metal roof panels. Cold-formed steel “cee” and “zee” shaped girts are used on the walls to span the distance between the primary rigid framed columns in order to support the metal wall panels. The girts and purlins are often coated with a rust-inhibiting primer (red oxide) or are unpainted galvanized steel members. Secondary framing members can be  punched with holes and slots in standard or custom patterns to accept connection bolts or bracing. 

Secondary framing can also include eave struts, channels, hat sections and angles to complete a building.
