Steel joists are open web lightweight steel trusses consisting of parallel chords and a triangulated web system, proportioned to span between bearing points. There are five main components: a top chord, bottom chord, end web, bearing seat, and interior web members. Steel joists (or open web steel joists in Canada) are typically made of hot-rolled or cold-formed steel with yield strength of 50 ksi and are typically designed and constructed in accordance with standards developed by the Steel Joist Institute. Steel joists are used on a variety of projects: industrial, commercial and other unique applications.
