The Steel Deck Institute (SDI), an ANSI member and accredited standards developer, has submitted the following updated scope of ASD accreditation on file with ANSI:

“The Steel Deck Institute (SDI) was incorporated in 1939 as a not-for-profit trade organization representing manufacturers of steel decks and products used in conjunction with steel deck. 

The SDI has provided uniform industry standards for the engineering, design, manufacture, and field usage of steel roof decks, composite floor decks, and form decks. As developments in steel products, steel manufacturing, steel design, and building methods have occurred, the SDI has continually revised and upgraded it standards as necessary. Continuing SDI functions include preparation, review, and distribution of literature, referral of inquiries to appropriate sources, coordination of research and testing, and liaison with other construction industry associations on matters of common interest. The Institute has been a major source of information and standards to the design community for their use in the preparation of project specifications and plans for the use of steel deck in construction. As an ANSI Accredited Standards Developer, SDI submits specifications and commentary for composite steel floor deck, non-composite steel floor deck (form deck), and steel roof deck as standards, and for structural members cold-formed to shape from carbon or low alloy steels.”

NOTE: The addition of “structural members cold-formed to shape from carbon or low alloy steels” is intended to accommodate the temporary responsibility for standards transferred from the American Iron and Steel Institute (AISI) to the SDI in December 2023. At such time that these AISI Standards are transferred to a new permanent standards developer, requirements related to this added scope will be removed.

Please forward any comments on the revised scope by December 25, 2023, to Thomas Sputo, Steel Deck Institute (SDI), (352) 378-0448, [email protected] (please copy [email protected]).
