Where fire rated designs utilize a proprietary steel joist, fluted unit, light gauge steel truss or steel stud, the source column appears shaded and the word proprietary is in bold font to allow ease of identification for an assembly built with a proprietary cold-formed steel product. Composite Steel Joists - UMDof floors in buildings, utilizing hot-rolled or cold-formed steel, including cold-formed steel whose yield strength has been attained by cold working. Shear connection between the joist top chord and overlying concrete slab allows the steel joist and concrete to act together as an integral unit after the concrete has adequately cured. Currently

Rolled Steel Joists. Joists are lightweight supporting members that form long-span support systems for the horizontal surfaces of a building, namely roofs and floors, by transferring their load onto columns and beams. Joists are typically smaller than beams, and tend to run parallel with them. NJR Steel supplies BS EN10025-2-S355 JR joists.
