Specialized equipment for a high-level government administrative agency
The headquarters of the Office of the President is located at No. 12 Ngo Quyen Street, Hoan Kiem Ward, Hanoi, within the grounds of the former Northern Palace. As the agency that directly advises and supports the President and Vice President in domestic and foreign affairs as well as state administration, the building has stringent requirements for the technical performance, aesthetics, and operational security of all architectural components.
To meet the standards of a central-level government building, Sonha Auto developed a supply and installation plan for two types of specialized door products:
- 01 NABCO Mini Fold Alpha automatic folding door installed at the main entrance.
- 40 Heinda automatic smoke exhaust windows installed across functional areas.

Technical solutions implemented by Sonha Auto
Optimizing passageway space with the NABCO Mini Fold Alpha automatic folding door
Instead of conventional horizontal sliding doors, the main entrance of the Office of the President is equipped with the NABCO Mini Fold Alpha automatic folding door system, imported as a complete unit from Japan.
The folding mechanism allows the door panels to fold compactly when opening, minimizing the interruption of usable space and maximizing the available passageway. This is an ideal solution for entrances requiring a high level of openness, combining convenience, sophisticated aesthetics, and high traffic volume at the headquarters.

Enhancing safety with 40 Heinda automatic smoke exhaust windows
Alongside the main passageway system, Sonha Auto completed the installation of 40 Heinda automatic smoke exhaust windows. In the event of a fire, the system operates automatically to exhaust smoke and hot gases to the outside, helping reduce the risk of smoke inhalation and supporting rescue operations and fire safety throughout the building. The large-scale deployment of 40 smoke exhaust windows demonstrates the project’s serious investment in active safety solutions.
The combination of the automatic folding door system for passageways and the fire safety smoke exhaust window system reflects a modern design approach: selecting equipment according to the specific function and operating characteristics of each location.
- Mini Fold Alpha addresses traffic flow and space-saving requirements.
- Heinda supports air control and emergency response.

Sonha Auto – A trusted provider of specialized door solutions
The installation project of automatic door and smoke exhaust window systems at the Office of the President further demonstrates Sonha Auto’s position in the supply and installation of automatic doors and safety equipment for key projects, including government agencies, office buildings, commercial centers, healthcare facilities, and more.
The entire process, from site survey and equipment consultation to imported equipment supply and completed installation, is carried out in accordance with stringent technical standards, providing partners with an optimized operating solution.
