SDI steel doors set the standards - and exceed yours
The Steel Door Institute (SDI) was established in 1954 as a voluntary, unincorporated, non-profit business association whose mission is to promote the use of steel doors and frames in the construction industry.
Representatives of SDI member companies create and publish manufacturing, quality and performance standards and distribute them to licensed architects and construction specifiers at no charge. These documents, collectively referred to as the Fact File, are available on this website as downloadable PDFs or in printed format.
Membership in SDI is open to all American-based companies engaged in the production for sale of swing steel doors and or frames and meeting other criteria. Members agree to establish and abide by SDI manufacturing and quality standards that apply to all doors and frames that they produce.
