Steel LIGHT GAUGE STEEL Light Gauge Steel Framing Members C-Studs Light gauge steel C-studs web depths range from 2 ½” to 14” Light gauge steel C-studs return depths include 3/8”, ½”, 5/8”, 1” Flange sizes range from 1 3/8” to 3” Tracks U-channels Used for bridging, blocking, and other reinforcing and bracing Standard sizes Depth ¾ to 2-1/2 in. Width ½ in. Example designation: 075U50-54 0.75 in. deep U-channel 0.50 inches wide 54 mils metal thickness Bridging Furring Channels Light gauge steel members are also used for furring Also called hat channels Standard sizes Depth 7/8 or 1-1/2 in. Width 1¼ in. at raised surface, 2½ in. at base Furring cont. Furring: Allows for the installation of flat wall finish over an irregular surface Provides a concealed space for installing plumbing, wiring and thermal insulation Other members used for furring are: Z-furring channel (Bottom left) Adjustable Furring brackets (bottom right) Framing Accessories L-Headers Section View Special Products Jamb Stud Specialized Channels Sheet Metal Thickness Minimum thickness of steel sheet Loadbearing Gauge framing Nonloadbearing framing 12 0.097 in.

Steel joists spaced from 12 to 24 in. o.c. are framed into tracks or channels. Web stiffeners or reinforcing are inserted where concentrated loads might cause joist webs to buckle. Construction panels are fastened with mastic adhesive and screws. Light Gauge Steel Compared to Light Wood Framing Advantages Like wood light framing: versatile, flexible, simple to construct Noncombustible and immune to insect attack Dimensionally stable, with consistent material properties Lighter weight Disadvantages Members require more frequent bracing Readily conducts heat and requires extra attention to eliminating thermal bridging effects Smaller labor pool
