Standards as Tough as Steel
What does "Standards as Tough as Steel" mean to architects, specifiers, building owners, and construction professionals who use SDI steel doors and frames?
It means that 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.
SDI tests steel doors and frames for strength, quality, consistency, security, weather and fire resistance, wear and tear, and longevity. Testing is undertaken in conjunction with the top testing labs in the country like UL, Intertek, National Fire Protection Association (NFPA), American National Standards Institute (ANSI), and American Society for Testing and Materials (ASTM). In addition, SDI works alongside industry associations representing related products such as Door & Hardware Institute (DHI), Construction Specifications Institute (CSI) and the Builders Hardware Manufacturers Association (BHMA) to ensure compatibility with products used in conjunction with steel doors and frames.
