Open Web Steel Jists Roof

Lh and dlh joists have heavier chords and web members for heavier loads and longer spans.

Open web steel jists roof.

In the late 1950 s redbuilt s founders invented an innovative composite steel and engineered wood open web truss. Typically used in non residential construction steel joists and joist girders provide an economical system for supporting floors and roofs. When using open web steel joists pay attention to the joist camber next to adjacent framing and walls. Steel joists joist girders.

In structural engineering the open web steel joist owsj is a lightweight steel truss consisting in the standard form of parallel chords and a triangulated web system proportioned to span between bearing points. This camber table was adopted years ago when steel joists in flat roof systems experienced difficulties due to. 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 k series joist web is a single bent bar running zig zag between top and bottom chords.

Our joists and girders are engineered and manufactured in accordance with the specifications of the steel joist institute. Open web steel joists are relatively light in weight fabricated in a shop setting and have a trussed web. Since then this design solution for architects and engineers has evolved to support large floor areas and large roof spaces of up to and over 100 feet wide.
