About the Steel Deck Insititute

For nearly 100 years, the Steel Deck Institute (SDI) has provided industry standards for the design, engineering, and manufacturing of steel deck, as well as its use in the field. More specifically, the SDI provides guidance for metal roof and floor deck design and manufacturing in detailed manuals.
It is the SDI’s mission to promote the advantages of steel deck for construction, including its durability and structural strength, sustainability, economic value, weather resistance, and physical appearance. To learn more about the Steel Deck Institute, visit the SDI website.
What It Means to Be a Steel Deck Institute Member
There are two levels of SDI membership: members and associate members. Members are metal roof and floor deck manufacturers, while associate members manufacture products that are used in the production of steel deck or its uses in the field.
To become a member, metal deck manufacturers must operate a facility within the United States that produces metal floor and roof deck that can be used to support roofing systems, reinforce floor systems, or serve as a permanent floor base. Additionally, each member must pass a detailed onsite audit to ensure that they are meeting and manufacturing deck according to SDI standards.
