Secondary Framing in Pre-Engineered Buildings (PEB)

Secondary framing in Pre-Engineered Buildings (PEB) is essential for supporting roof and wall panels and transferring loads to the primary framing. It includes components like Roof Purlins, Wall Girts, Eave Struts, and Sag Rods, which contribute to structural stability and integrity. In this article, we'll explore the significance and functions of these secondary framing members in PEB construction.

How It Works

Rigid Frames

Roof purlins are vital horizontal structural elements, supporting the roof covering and transferring loads to the primary frame. Usually shaped as "C" or "Z", they're cold-formed to match design needs. Their depth and thickness vary according to the building's design and load requirements. Installed in one direction, they're bolted downhill from the clip, ensuring stability and strength in Pre-Engineered Buildings (PEBs).

Wall Girts

Wall girts, cold-formed Z-shaped members, are crucial secondary structural elements in Pre-Engineered Buildings (PEBs). Available in different thicknesses and depths, they adapt to the building's design requirements. Attached to the external extensions of columns along the walls, they offer vital support to wall panels. Their adaptable design enables efficient load distribution, enhancing the building's stability and structural integrity.

Eave Struts

Eave Struts are secondary steel framing members tailored for support at the eaves and high side peaks of Pre-Engineered Buildings (PEBs). Available in single or double slopes, they offer flexibility with upward or downward styles. Finished in red oxide or galvanized, they're precisely cut to the nearest 1/8 inch. These struts are essential for preserving structural integrity and alignment at the eaves and peaks, ensuring stability and strength in PEBs.

Sag Rods

Sag rods are utilized to prevent the sagging of open-web steel joists, commonly employed as purlins with their depth oriented at right angles to the roof slope. These rods offer crucial lateral support for both Girts and Purlins, enhancing the stability and load-bearing capacity of the secondary framing system. This added support ensures the alignment and spacing of these structural members are maintained effectively.

Sag Angles

Sag angles are used to provide alignment the purlin and girt for the attachment of the steel panels and to reduce their tendency to bend laterally and twist. Sag angle will increase the allowable strength of purlin and girt.

Importance of Secondary Framing in Pre-Engineered Buildings (PEB)

In summary, secondary framing components are crucial for the structural integrity and load-bearing capacity of Pre Engineered Buildings (PEB). Roof Purlins, Wall Girts, Eave Struts, and Sag Rods collaborate to support roof and wall panels, efficiently transferring loads to the primary framing system.
