High-Quality Door Lock Solutions for Every Application

door lock solution for office building
 
OFFICE BUILDING
 

When selecting door locks for office buildings, it’s important to consider both security and functional zoning. Main entrances, meeting rooms, executive offices, and storage areas each require different locking functions. 

CE or UL certified mortise locks should be installed on fire-rated doors to meet safety standards. Use EN1303 high-security cylinders and EN1906 handles for durability and smooth operation in high-traffic areas. Finishes should align with the building’s modern or corporate style. 

Integration with access control systems, door closers, and panic exit devices ensures smooth daily operation. The right lock choice enhances professional security management and architectural aesthetics for the entire office environment.

COMMERCIAL
 

Commercial buildings such as shopping malls, showrooms, and mixed-use facilities demand locks that provide high durability and public safety. These spaces have heavy daily traffic, requiring EN12209 or UL 10C certified mortise locks tested for long life and fire resistance. Entrances, corridors, and service areas need different lock functions to manage access effectively. 

Corrosion-resistant finishes and stainless steel materials ensure long-term performance. 

Locks should be compatible with door closers and panic bars to meet emergency exit requirements. 

For retail spaces, choose locks that combine security with modern design, supporting both safety regulations and customer convenience.

GOVERNMENT
 

Government buildings require door locks that combine high security, fire safety, and controlled access. Offices, archives, and restricted areas demand UL or CE certified mortise locks with EN1303 cylinders for master key systems and anti-pick protection. Public entrances and corridors should use durable EN1906 handles tested for high-frequency use. Since these facilities often handle confidential documents and sensitive operations, tamper-resistant and fire-rated locks are essential.The lock design should reflect authority and professionalism, with finishes like stainless steel or matte black. Integration with electronic access control or key management systems ensures efficient and secure daily operations across departments.

HEALTHCARE
 

Healthcare buildings such as hospitals and clinics require locks designed for safety, hygiene, and reliability. Locks must support easy operation, even in emergencies, while ensuring restricted access in areas like pharmacies or laboratories. UL fire-rated and CE mortise locks are recommended for patient room and corridor doors. Handles with EN1906 certification and anti-bacterial stainless steel finishes help maintain hygiene standards. Quiet operation is crucial for patient comfort, and fail-safe locking systems ensure quick evacuation when needed. Cylinders tested to EN1303 standards provide secure key management. 

Choosing the right hardware improves infection control, safety compliance, and operational efficiency within healthcare environments.

HOTEL
 

Hotel door locks must balance security, convenience, and aesthetics. Guestroom doors often use electronic or mortise locks with privacy and keycard functions, while back-office and service doors require mechanical UL or CE mortise locks for strength and fire resistance. EN1303 cylinders provide key control for master key systems, ensuring efficient management. Handles should meet EN1906 durability standards and match the hotel’s interior design. 

Locks on fire-rated and emergency exit doors should comply with EN1634 and UL 10C. It’s also important to ensure quiet operation and corrosion resistance for long-term reliability. Selecting the right locks enhances guest safety, staff efficiency, and overall hotel experience.
