SF0010PE - SECONDARY FRAMING

1. Standard Secondary Framing consists of Cold Formed “Z” shaped roof purlins and wall girts. “C” shaped wall girts may be used for framed openings and other special applications.

2. “Z” and “C” members are shop punched for simple field bolted connections. 3. “Z” and “C” members are available in either 8 or 10 inch depths. 12 and 14 inch

members depths are available on a limited basis. Consult the plant for specifics. 4. Optional Open-Web joists are available for wide bay applications with spans over

40 feet, and for mezzanine applications. 5. All section properties listed in this section were determined using the proper

provisions of the “Cold-Formed Steel Design Manual”, AISI, 1996 Edition. Any use of these properties for design should also be completed per these provisions.

6. As a standard, all bypass roof purlins and wall girts will utilize a shop welded clip. Bolted clips are also available.

7. Some Nucor Divisions may offer welded clips for inset or flush girts. Contact your NBS Division for availability.

DETAIL NAME IF APPLICABLE 4.3.13

CLEARBAY CFR • This system is only available for projects with roof joists and CFR panels. • The ClearBay CFR system was set in place to minimize joist bridging by utilizing

the capacity of the CFR roof panel system. This reduction in bridging will also result in a reduction of cost.

• ClearBay CFR is available in a welded and all bolted option. • These joists will be detailed the same as our typical roof joist system. The

reduced bridging will be specified by Vulcraft. • Click the link below to see the predetermined bridging rows and spacing for bays

that are 40’ to 60’in width. Any bay sizes other than these would be custom quoted. This table only applies to ClearBay CFR projects. ClearBay CFR Bridging Locations



DETAIL NAME IF APPLICABLE 4.3.14

SF0080PE - COLD-FORMED BOX BEAMS 1. Cold-formed box beams consist of two “C” or “S” sections, forming a cold-formed “tube”. 2. These tubes may be square or rectangular in shape. 3. The height of the box beam matches the purlin depth. The depth of the box beam will be 8”,

10”, or 12”, depending on the design requirements of a particular project. 4. Cold-formed box beams are typically used as a replacement for the eave strut, eave purlin, or

strong-back eave beam. 5. Standard connection for the box beam to primary framing member is with either (2) or (4) ½”

diameter A325 bolts per end.
