**Q: Can D&D Hardware provide custom solutions for specific building codes?** A: Yes. D&D Hardware has an in-house design team and offers full OEM/ODM customization. We can engineer door hardware solutions to meet specific local building codes, project specifications, or aesthetic requirements. Our team works directly with architects, contractors, and distributors to ensure compliance with regional standards including IBC, NFPA 80, EN 1154, and local fire codes. We also offer project-specific hardware schedules and technical support throughout the specification and procurement process. - **Q: What door hardware is required for hospitals and healthcare facilities?** A: Healthcare facilities require specialized door hardware addressing hygiene, accessibility, and fire safety:  ADA/EN81-70 compliant lever handles  (round knobs are prohibited);  antimicrobial or easy-to-clean finishes  such as stainless steel or brushed nickel for infection control;  fire-rated door closers and hinges  for all corridor and stairwell doors;  panic exit devices  for emergency egress routes; and  smooth, quiet operation  for patient comfort. D&D Hardware provides a complete healthcare door hardware package certified to UL, CE, and ANSI standards. - **Q: What is the difference between ANSl Grade 1, Grade 2,and Grade 3?** A: ANSI/BHMA grades classify door hardware by durability and security level:  Grade 1  is heavy-duty commercial grade (500,000 cycles for locks, 2,500,000 for hinges), required for high-traffic commercial buildings such as hospitals, schools, and offices.  Grade 2  is medium-duty commercial/light commercial (250,000 cycles), suitable for light commercial applications.  Grade 3  is residential grade (150,000 cycles), intended for home use only. D&D Hardware's commercial product line meets ANSI Grade 1 standards, making them the correct specification for all commercial projects. - **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. - **Q: What certifications are required for commercial door hardware?** A: Commercial door hardware certification requirements vary by region and building type. In  North America , UL Listing and ANSI/BHMA Grade 1 compliance are standard, with NFPA 80 governing fire door assemblies. 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.
