There are several methods by which fire ratings can be readily achieved for structural-steel floor framing systems. These methods include application of spray-on fire protection, en casement of the framing members in a fire-rated assembly, or installation of a fire-rated ceiling system below the framing. For open-web joists and lightweight steel framing, the last two options are usually more practical because spray-on fire protection of such members tends to be difficult. (See also Art. 6.32.)
