The need for secondary steel often arises for heavy items mounted on gypsum board walls and ceilings when the stud framing itself is not structurally sufficient to carry the load. Secondary steel in this case is constructed in line with the stud framing to augment its structural capacity. Coiling doors and ceiling mounted toilet partitions are two examples of when secondary (also commonly termed supplemental or miscellaneous) steel will be required behind or above the gypsum board. Coiling door and ceiling mounted toilet partition fasteners will actually bridge though the gypsum board and fasten directly to the concealed secondary steel.
