The Steel Joist Institute (SJI), a nonprofit organization of active joist manufacturers and other organizations and companies connected to the industry, was founded in 1928 to address the need for uniform joist standards within the industry. Today, the Institute continues to maintain the standards for steel joist construction. In addition, the SJI provides educational opportunities for construction professionals utilizing a library of printed publications and both live and recorded webinars. We also offer assistance in identifying existing joists in buildings undergoing retrofit.
Steel Deck Institute
Founded in 1939, the Steel Deck Institute (SDI) is a trade association representing steel deck manufacturers and those manufacturing products used in conjunction with steel deck. The SDI actively publishes design manuals, develops standards for steel roof and floor deck, offers website tools, provides an industry standard EPD, offers educational opportunities, and supports research related to steel deck. Our most recent publications are the 2022 ANSI Standards. These include the new and combined ANSI/SDI SD-2022, and the renewed ANSI/SDI T-CD-2022 and ANSI/SDI QA/QC-2022. Download at www.sdi.org.
Seismic Bracing Company
We are makers of Buckling Restrained Brace (BRBs). The state of the art braces for bracing buildings and other structures during earthquakes. As the name implies, BRBs do not buckle. They smash and stretch axially absorbing seismic energy. We have patented a simple, easy and repeatable methods to manufacture BRBs, which brings better value to projects. Our methods have been fully tested and exceed governing building code requirements. All our projects to date have been a great success for our clients and us.
SCHULLER&Company
SCHULLER&Company supports companies in the building industry on their journey towards digitalization. In May 2022, SCHULLER&Company acquired bocad, a detailing software for structural engineering that has been setting standards in steel construction since 1983. bocad is a recognized and proven software used by renowned companies worldwide, with over 500,000 projects successfully delivered. It is known for its high level of quality and accuracy in automatic fabrication deliverables, which helps to avoid wasted time editing drawings, reduces the risk of errors, and minimizes rework on site.
