Lh and dlh joists have heavier chords and web members for heavier loads and longer spans. Sds formerly msds technical information. Some of the first steel joists used in the united states in the mid to late 1800s were made of sheet steel webs and flanges riveted together. Single pitched top chord joists.

Founded in 1973 canam steel corporation csc is a service oriented manufacturing company that manufactures open web steel joists and a variety of steel deck products. Open web steel joists are an engineered truss like construction component used to support loads over short and long spans alike. These concentrated loads often include standard steel joists that are in turn supporting steel roof or floor deck. In the late 1950 s redbuilt s founders invented an innovative composite steel and engineered wood open web truss.

The k series joist web is a single bent bar running zig zag between top and bottom chords. The open web design of steel joists and joist girders introduce a range of cost and performance advantages. In order to accurately design an owsj engineers consider the joist span between bearing points joist spacing slope. Planning design tools.

Open web steel joists are relatively light in weight fabricated in a shop setting and have a trussed web. Typically used in non residential construction steel joists and joist girders provide an economical system for supporting floors and roofs. And making erection easier and faster. Multi pitched top chord joists.

Double pitched top chord joists. 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. 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.
