Industry-Wide Steel Door and Frame Glossary
Terminology and Technical Drawings from the Experts


The Steel Door Institute (SDI) and Hollow Metal Manufacturers Association (HMMA) recently joined forces to develop an industry-wide glossary on steel doors and frames. Now available on the DCI website, it has more than 250 industry trade terms useful to dealers, architects, contractors, and other industry professionals.

The glossary provides a user-friendly interface for browsing or searching definitions. Technical drawings are included with many of the definitions to provide further clarification.

As an active member of SDI and HMMA, DCI participated in the Technical Committee that developed this comprehensive glossary.

The glossary is just one resource of 19 in Door Component’s "Library," one of the most popular sections of the website. We've enhanced it over time with information such as cutsheets, Substitution Request Forms, and product Catalogs in response to your requests.

While we consistently develop our website with the most recent technical information, you are always welcome to contact us with questions.  Send an email to or call Chuck Kiley, Vice President of Sales and Marketing, at 909.367.0292
