Healthcare

Healthcare openings must support the safe movement of patients, staff and medical equipment.

Office & Commercial

Office buildings contain public, private and shared spaces with different operating requirements. Reception entrances and meeting rooms should feel welcoming and operate smoothly, while private offices, archives and equipment rooms need reliable locking functions.

Glass partitions and modern interiors also require hardware with clean designs and coordinated finishes. D&D helps organize locks, cylinders, hinges, closers and exit devices according to door type and traffic level. ANSI/BHMA performance grades can support selection for frequently used commercial doors, while UL 10C, EN 1634 or locally approved hardware may be specified for fire-rated openings.

Public & Government

Government buildings must provide convenient public circulation while maintaining dependable operation across administrative and functional areas. Service halls need intuitive door operation, while offices, archives, courtrooms and document rooms require durable locking hardware.

Formal procurement projects often place greater importance on traceable certification, technical documentation and consistent specifications. D&D supports these requirements with heavy-duty locks, hinges, closers and egress hardware. Products can be selected under ANSI/BHMA, UL, CE or EN systems according to the project location. Certified fire-rated and panic hardware can also be documented for protected corridors, stairwells and public evacuation routes.

Transportation

Airports, railway stations and metro facilities operate for long hours and experience concentrated passenger traffic. Terminal entrances and connecting corridors require high-cycle hardware, while baggage areas, equipment rooms and staff facilities need dependable, durable door solutions.

Exterior openings may also face moisture, pollution and temperature changes. D&D provides hinges, door closers, locks and exit devices selected according to door weight, exposure conditions and traffic flow. UL 305 panic hardware or EN 1125 exit devices may be used for public evacuation routes, while UL 10C or EN 1634 products can support fire-rated openings. Certified performance helps maintain reliability across large transport facilities.

Malls & Retail

Retail environments must provide convenient customer access while supporting the security of merchandise, stockrooms and service areas. Mall entrances and anchor stores experience continuous traffic, whereas individual storefronts need hardware that complements their brand design.

Restaurants, cinemas and entertainment spaces introduce additional occupancy and evacuation requirements. D&D supplies locks, closers, hinges and exit devices for glass storefronts, metal service doors and interior retail openings. High-cycle ANSI/BHMA products can support busy entrances, while UL 305 or EN 1125 hardware may be specified for public exits. Fire-rated doors can also use hardware tested to UL 10C, EN 1634 or applicable local standards.

Sports & Exhibition

Sports arenas and exhibition centers must manage rapid changes in occupancy before and after events. Main entrances and spectator concourses need robust hardware, while changing rooms, storage areas and technical spaces require durable door solutions.

Exhibition halls may also contain large doors used for equipment movement and temporary installations.

Panic hardware tested to UL 305 or EN 1125 can support safe evacuation from assembly areas. Certified fire-rated hardware may also be specified for protected corridors, service zones and stairwells within the venue.

Residential

Residential hardware should make everyday access secure, quiet and convenient. Apartment entrance doors need privacy and dependable locking, while shared lobbies, corridors and clubhouses require durable products for repeated use.

Parking areas, plant rooms, management offices and service spaces have different door functions and operating conditions. D&D provides locks, cylinders, lever handles, hinges and door closers for private and common-area openings. Fire-rated apartment entrances and escape routes may require hardware tested to UL 10C, EN 1634 or applicable residential codes. Certified door closers and hinges can provide documented durability while supporting consistent appearance and straightforward long-term maintenance.

Building renovation project and door hardware replacement project

Renovation projects begin with existing doors, frames and hardware preparations. Replacement products must match the original dimensions, handing, fixing positions and operating functions. Worn hinges, leaking closers or outdated locks should be replaced without unnecessary modifications to usable doors and frames.

Fire and escape doors require additional attention because replacement components may affect the certification of the complete assembly. D&D assists with product identification, dimensional comparison and functional matching. UL, ANSI/BHMA, CE or EN documentation can be reviewed against the original project requirements, helping buyers select compatible replacement hardware while improving safety, operation and maintenance.
