SDI Standards for Steel Deck

Current SDI Standards

The current editions of the SDI Standards are the 2022 editions.  Earlier editions were referenced in earlier editions of the Building Codes and are shown below for reference.

Current SDI Standards that are referenced in the 2024 International Building Code and the 2024 NFPA Building Construction and Safety Code:

ANSI/SDI SD-2022 Standard for Steel Deck

The ANSI/SDI SD-2022 Standard for Steel Deck consolidates and extends the coverage of the 2017 editions of the ANSI/SDI RD, NC, and C Standards into a single standard. This Standard has been developed as a consensus document to provide a uniform practice in the design of steel deck used for roof and floor applications. The intention is to provide design criteria for routine use and not to provide specific criteria for infrequently encountered problems, which occur in the full range of structural design.

ANSI/SDI QA/QC-2022 Standard for Quality Control and Quality Assurance for Installation of Steel Deck

This Standard has been developed as a consensus document to provide a uniform practice for ensuring quality in the installation of steel deck used for roof and floor applications. The intention is to provide criteria for routine use and not to provide specific criteria for infrequently encountered problems, which require special consideration by the Designer.

ANSI/SDI T-CD-2022 Test Standard for Composite Steel Deck-Slabs

This Standard has been developed as a consensus document to provide a uniform practice in the testing of composite steel deck-slabs.

SDI Standards that are referenced in the 2018 and 2021 editions of the International Building Code and the 2018 and 2021 editions of the NFPA Building Construction and Safety Code:

ANSI/SDI C-2017 Standard for Composite Steel Floor Deck – Slabs

This Standard for Composite Steel Floor Deck-Slabs shall govern the materials, design, and erection of composite concrete slabs utilizing cold formed steel deck functioning as a permanent form and as reinforcement for positive moment in floor and roof applications buildings and similar structures.

  1. SDI Errata No. 1 to ANSI/SDI C-2017 – November 2017

ANSI/SDI QA/QC-2017 Standard for Quality Control and Quality Assurance for Installation of Steel Deck

This Standard for Quality Control and Quality Assurance for the Installation of Steel Deck shall govern the minimum requirements for quality control and quality assurance for material control and installation of cold-formed steel deck and deck accessories used for floor and roof applications in buildings and other structures.

ANSI/SDI T-CD-2017 Test Standard for Composite Steel Deck – Slabs

This Standard shall apply to testing of composite steel deck-slabs under load transverse to the deck span, and the determination of the nominal resistance and stiffness thereof.

• Please Note: The following updates are available for ANSI/SDI T-CD-2017:

1. 1. Interpretation No. 1 to ANSI/SDI T-CD-2017 – January 2018
   2. SDI Errata No. 1 to ANSI/SDI T-CD-2017 – November 2017

ANSI/SDI RD-2017 Standard for Steel Roof Deck

This Standard for Steel Roof Deck shall govern the materials, design, and erection of cold-formed steel deck used for roof applications in buildings and similar structures.

ANSI/SDI NC-2017 Standard for Non-Composite Steel Floor Deck

This Standard for Non-Composite Steel Floor Deck shall govern the materials, design, and erection of cold-formed steel deck which is used as a form for structural concrete slabs in floor and roof applications, or as the primary load carrying element without a structural concrete slab, in buildings and similar structures.
