Concerns with steel roof decks
Steel roof decks are the most popular roof deck type used in the U.S. However, inconsistencies between design methods used for steel roof decks and roof systems are cause for concern.
Steel roof decks typically are designed using guidelines developed by the Steel Deck Institute (SDI).
Historically, SDI's design guidelines for steel roof decks have been published in various editions of SDI's Design Manual for Composite Decks, Form Decks and Roof Decks. SDI has revised and updated its manual a number of times during the years. For example, the 2007 edition is referred to as "Publication No. 31."
