PrimeWall® Stud

PrimeWall Stud

The PrimeWall® Drywall Studs are used in non-load-bearing wall systems that support gypsum board construction.

Each PrimeWall Stud contains knurled flanges for fast fastener placement when connecting sheathing. Pre-punched knockouts are spaced at regular intervals for rapid installation of bridging, electrical wiring, and plumbing.

Because The Steel Network is committed to improving overall quality in the construction industry, we insist on utilizing traceable material for all steel in the manufacturing of the PrimeWall Series.

1 Minimum thickness represents 95% of the design thickness and is the minimum acceptable thickness delivered to the job site based on Section A2.4 of AISI S100-07.
2 The tables in this catalog are calculated based on inside corner radii listed in this table. The inside corner radius is the maximum of 3/32 - t/2 or 1.5t, truncated after the fourth decimal place (t = design thickness.) Centerline bend radius is calculated by adding half of the design thickness to listed corner radius.

1 Web-height to thickness ratio exceeds 200. Web Stiffeners are required at all support points and concentrated loads.
2 When web height to thickness ration exceeds 260, or flange width to thickness ratio exceeds 60, effective properties are not calculated (limitations in AISI S100-07 Sec. B1).Allowable moment includes cold-work of forming.

Notes:

  • Calculated properties are based on AISI S100-07, North American Specification for the Design of Cold-Formed Steel Structural Members.
  • The centerline bend radius is based upon inside corner radii shown in the Thickness Table in SFIA Technical Guide for Cold-Formed Steel Framing Products.
  • Effective properties incorporate the strength increase from the cold work of forming as applicable per AISI S100-07 Sec. A7.2.
  • Tabulated gross properties, including torsional properties, are based upon full-unreduced cross section of the studs, away from punchouts.
  • For deflection calculations, use the effective moment of inertia.
TSN's Product Catalogs are an essential resource for the design of cold formed steel.  Developed by Engineers, the catalogs contain design data for members connectors, and fasteners.
