Definitions

  • the present invention relates to cold formed metal studs for composite and non- composite applications in residential and commercial construction projects.
  • Studs are commonly used in the construction industry to provide a support for a wall surface and further support a roof, a floor or the like. Studs can be comprised of a variety of materials including wood and metal. Metal studs are commonly used in a variety of construction styles as they can be manufactured economically and are light, strong and durable.
  • Metal studs are commonly fashioned from a piece of sheet metal that is cold formed to desired specifications. Cold forming involves working a material below its recrystallization temperature. Generally, cold forming occurs at the ambient temperature of the work environment. The resultant cold formed material is stronger due to manipulations that have been made to the crystal structure of the material. Cold forming is an economical manufacturing process as it does not require the significant energy input required to raise the material above its recrystallization temperature. Cold forming has the further advantage of providing steel structural components that have increased yield capacity in comparison to steel structural components that have not been cold formed. [005] Pre-fabricated metal studs are well-known in the construction industry. However, there is a distinct lack of metal studs that have been specifically designed for use with both composite and non-composite applications.
