Cold-Formed steel has been widely used in commercial buildings, especially in non-load bearing (partitions) and curtain wall applications. Cold-Formed steel sections are increasingly used as primary structural members, such as beams and columns, or as load-bearing walls or partitions in commercial and residential construction. In most cases, these members are required to be fire resistant where they are part of a compartment wall or floor, or where they support other floors. The purpose of this Tech Note is to provide the user with a comprehensive list of resources summarizing available tested fire rated steel assemblies, building code requirements, test methods and applicable references.
