Open web steel jists roof.

K series bar joists are designed for use typically with lighter loads and are most common in roof design. In order to accurately design an owsj engineers consider the joist span between bearing points joist spacing slope. For roof drainage joists may be pitched one way or two way. If the joists are not pitched the roofing insulation is often presloped.

These concentrated loads often include standard steel joists that are in turn supporting steel roof or floor deck. Open web steel joists are an engineered truss like construction component used to support loads over short and long spans alike. The main function of an owsj is to provide direct support for roof or floor deck and to transfer the load imposed on the deck to the structural frame i e. The lightweight nature of open web steel joists is very similar to wood joist construction.

K joists are used typically where shorter span conditions are required. Typically used in non residential construction steel joists and joist girders provide an economical system for supporting floors and roofs. The open web design of steel joists and joist girders introduce a range of cost and performance advantages. In structural engineering the open web steel joist is a lightweight steel truss consisting in the standard form of parallel chords and a triangulated web system proportioned to span between bearing points.
