Q How do l choose fire-rated door hardware for a commercial building?
A Selecting fire-rated door hardware requires matching the hardware's fire rating to the door assembly's rating. Key considerations include:
(1) Fire rating duration — 30, 60, 90, 120, or 180+ minutes depending on the door's location and building code requirements;
(2) Certification standard — UL 10C for North America, EN1634 for Europe/UK;
(3) Complete assembly compliance — all hardware components (hinges, closers, locks, and panic devices) must be fire-rated;
(4) ADA/accessibility compliance. D&D Hardware offers fire-rated hardware certified up to 260 minutes under EN1634 and 3 hours under UL Listed for North American projects.

In Europe, CE marking and compliance with BS EN standards (EN 1935, EN 1154, EN 12209, EN 1125) are required. In the UK, BS EN standards and EN1634 fire testing apply. D&D Hardware products carry UL, CE, ANSI, BHMA, BS EN, SGS, and Intertek certifications, making them suitable for commercial projects worldwide.
