General Cold-Formed Steel Framing FAQs

Cold-formed steel (CFS) framing involves creating structural members from sheet steel through a process of rolling or pressing at room temperatures. This method is praised for its high strength-to-weight ratio and flexibility in design, making it ideal for various building applications. To ensure optimal performance, pay careful attention to bracing during construction.

Curtain Wall Framing

Curtain wall framing is braced by the standard attachment of wall facing materials to both sides of the studs. During construction, the use of these materials for bracing must be carefully considered. Although sheathing is generally applied to the exterior of the studs, the inside flanges often remain unbraced until the interior finish is applied. High winds can cause damage to studs due to this lack of interior bracing before the interior board is installed.

Temporary and Mechanical Bracing

Steel strapping, installed horizontally on the interior flanges at a maximum of six (6) feet on center, in tandem with the sheathing, will brace and protect the stud framing during construction. If mechanical bracing is required, it can be either steel strapping run horizontally on both sides of the studs and attached to each flange or a cold-rolled channel run horizontally through the stud punchouts and attached to each stud web. The maximum spacing for mechanical bracing of curtain wall framing is six (6) feet on center.
