SigmaStud®

SigmaStud® is a breakthrough in metal stud framing, load bearing members, producing significant increases in load capacity when compared with conventional “C” Shaped metal studs. Its unique sigma configuration provides installation and design advantages which create efficiencies no other light steel framing (LSF) studs can provide for load bearing walls.

Each bend made to a flat LSF (light gauge metal) element increases load capacity over a standard stud section with the same material thickness. Six extra bends result in delivering the most efficient LSF load-bearing stud member available in the industry.

Features
  • Increases load capacity over a standard “C-shaped” stud of the same thickness, reducing overall materials needed (14ga “C-shaped” to 18ga “SG” common)
  • Re-defines previous limitations considered for utilization of steel studs in building construction
  • Larger flange width increases area for fasteners
  • Axial load capacity tables compatible with recent code changes
  • Lighter weight results in shipping efficiencies and easier handling & faster connections
  • Screw size decreases with thinner material thickness of member material
  • Eliminate or reduce double studs / stud packs and their attachments to each other
  • Increased load capacity produces more cost-effective options for designing load bearing walls for clients

Notes:

  • Section properties and capacities are calculated in accordance with AISI S100-16 Specification.
  • Tabulated gross properties are based on the full-unreduced cross section of the studs, away from punchouts.
  • Effective section properties incorporate the strength increase from the cold-work of forming as applicable per AISI S100-16 Spec, Sec. A3.3.2 (3).
  • Net effective section properties are calculated at a cross section through the punchout.
  • Allowable moment is the lesser of Mal and Mad. Stud distortional buckling is based on an assumed kΦ = 0.
  • For deflection calculations, use the effective moment of inertia.
  • The effective moment of inertia for deflection is calculated at a stress which results in a section modulus such that the stress times the section modulus at that stress is equal to the allowable moment. AISI S100-16 Specification Procedure I for serviceability determination has been used.

Notes:

  • Section properties and capacities are calculated in accordance with AISI S100-16 Spec, “North American Specification for the Design of Cold-Formed Steel Structural Members”.
  • Tabulated gross properties are based on the full-unreduced cross section of the studs, away from punchouts.
    Effective section properties incorporate the strength increase from the cold-work of forming as applicable per AISI S100-16 Spec, Sec. A3.3.2 (3).
  • Allowable moment is the lesser of Mal and Mad. Stud distortional buckling is based on an assumed kΦ = 0.
  • For deflection calculations, use the effective moment of inertia.
  • The effective moment of inertia for deflection is calculated at a stress which results in a section modulus such that the stress times the section modulus at that stress is equal to the allowable moment. AISI S100-16 Procedure I for serviceability determination has been used.
