Is cold rolled channel required on interior walls?

Cold rolled channel is not typically required for interior walls, as the framing can often be achieved with standard wood or metal studs. However, it may be used in specific situations, such as for added structural support, when creating non-load-bearing walls, or in commercial applications where fire resistance and durability are prioritized. Ultimately, the decision depends on building codes and the specific design requirements of the project. Always consult with a structural engineer or architect for guidance.
