The Steel Door Institute produces quality and performance standards for steel doors and frames. And as the door and hardware industry evolves, our standards are updated to reflect current best practices. By specifying steel doors and frames to our standards and from SDI Certified manufacturers, you can be assured to receive high-quality products that fit your specific needs. Anyone specifying or purchasing a steel door or frame from an SDI member company can be confident that the product has been tested and approved by the most respected laboratories in the country, and that it's backed up by a commitment to service and support you can count on.
Steel doors and frames are often specified as a standard product. However, design professionals are increasingly putting a new twist on an old classic by modifying them for better aesthetics or performance. These are the most common steel door upgrades. Fire rated doors and frames play a vital role in keeping people safe and minimizing property damage. Hollow metal is the only material widely available as a 3 hour fire rated door. Browse a variety of resources to help bring you up to speed on fire rated doors and frames.
