Open web steel joist roof.

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. Every open web truss is custom manufactured to the precise specifications of the individual project and designed to support the loads. The k series joist web is a single bent bar running zig zag between top and bottom chords. In the late 1950 s redbuilt s founders invented an innovative composite steel and engineered wood open web truss.

Engineered open web joists in our constant efforts to offer customers the latest in construction innovation we recently branched into the design and manufacture of open web joists an alternative to conventional timber joists or concrete floor slabs. Open web steel joists are relatively light in weight fabricated in a shop setting and have a trussed web. Allowing for seamless integration of mechanical electrical and plumbing mep systems. 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.

Planning design tools. Typically used in non residential construction steel joists and joist girders provide an economical system for supporting floors and roofs. We offer superior products personalized customer service and a proactive approach to safety for customers and employees alike all to meet your unique needs and to keep your project right on schedule. 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.

These concentrated loads often include standard steel joists that are in turn supporting steel roof or floor deck. The open web design of steel joists and joist girders introduce a range of cost and performance advantages. Open web steel joists are an engineered truss like construction component used to support loads over short and long spans alike. And making erection easier and faster.

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. Multi pitched top chord joists. 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. All vulcraft joists and joist girders are designed and manufactured in accordance to the exacting specifications of the steel joist institute.

Sds formerly msds technical information. Double pitched top chord joists. Lh and dlh joists have heavier chords and web members for heavier loads and longer spans.
