SDI tests

- Dec 26, 2018-

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 Underwriters Laboratories (UL), 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.
