Studs are vertical structural elements used in wall construction to create the framework of a building. They provide support for the wall coverings and help transfer the weight of the structure above to the foundation below. Typically spaced evenly throughout a wall, studs also create cavities for insulation and space to run electrical wiring and plumbing. Whether made of wood or metal, studs are essential for maintaining the strength, shape, and stability of interior and exterior walls in both residential and commercial buildings.
