Drywall Framing System
C-Joist components provide an economical, lightweight alternative to open web trusses, bar joists, engineered lumber, cast-in-place or hollow core floor assemblies. Depending on loads and spans, C-Joists are typically spaced at 12", 16", 19.2" or 24" on-center spacing. Structural track, usually in the same gauge as the joist, is used as rim or band enclosures. Joist to girder attachments are normally supported with joist hangers, EasyClip™ E-Series™ or S-Series™ support clips. Web stiffeners may be required at supports and other point loads. Solid blocking and strap bridging is required to properly brace the floor assembly.
