In fire incidents, toxic smoke and high temperatures are the most dangerous factors, directly affecting the ability to escape and rescue efforts. If the ventilation system is not properly designed and controlled, the ductwork itself can become a "pathway" for smoke to spread rapidly, increasing the risk of fire spreading.
Using fire-resistant air ducts in Hai Phong offers practical benefits:
- Prevent the spread of fire through utility shafts, basements, and corridors.
- Controls smoke and heat flow, supports smoke extraction systems, and increases stairwell pressurization.
- Creating a "golden hour" allows people to escape and firefighters to intervene in time.
Therefore, this type of air duct is mandatory in many fire protection systems for high-rise apartments, factories, shopping malls, and industrial buildings in Hai Phong.
Outstanding advantages of fire-resistant air ducts in Hai Phong.
Fire-resistant air ducts in Hai Phong stand out with their high heat resistance, optimal airtightness, and superior durability, ensuring fire safety for various types of buildings. The product is flexible in installation and easily integrates with HVAC systems, helping to maintain stable ventilation performance even in emergency situations.
Fire resistance meets standards.
Fire-resistant ducting in Hai Phong is designed to withstand continuous heat for 30 to 120 minutes, depending on the EI rating (EI30, EI60, EI120). This minimizes the risk of fire spreading between areas and ensures the ventilation system remains stable in emergency situations.
High airtightness and durability
The product is precisely machined and securely joined, minimizing air and smoke leaks. At the same time, high-quality materials extend the system's lifespan, reduce maintenance costs, and ensure long-term, stable operation.
Suitable for many types of construction projects.
From civil engineering projects, shopping malls, high-rise offices to factories and industrial parks, fire-resistant air ducts in Hai Phong meet all technical requirements. The product can be installed in corridors, technical shafts, basements, or escape areas while ensuring fire safety.
Easily integrates with HVAC systems.
Fire-resistant ducting can be flexibly combined with exhaust fans, fire dampers, air grilles, and other accessories in HVAC systems, helping to distribute airflow evenly and stably while maintaining air conditioning performance.

Fire-resistant air ducts in Hai Phong play a crucial role in protecting people and property in various types of buildings, from apartments and offices to shopping malls and hospitals. The product helps control smoke, isolate fires, and maintain safe ventilation, which is especially important in sensitive areas such as basements, parking lots, and industrial workshops.
High-rise apartment buildings and office buildings
In high-rise apartment buildings, corridors, technical rooms, and ventilation shafts always pose a risk of fire spread. Using fire-resistant ventilation ducts in these areas helps isolate fires, control smoke, and protect residents.
Office buildings are also places where many people congregate, therefore installing fire-resistant ventilation ducts in technical shafts, stairwells, corridors, and basements helps increase escape time and protect the safety of employees and customers.
Shopping malls, hotels, and hospitals
Commercial and service buildings such as shopping malls, hotels, and hospitals have high foot traffic. Fire-resistant air ducts in these areas not only supply fresh air but also control smoke in case of an emergency, ensuring effective fire protection and enhancing the building's reputation.
Factory and industrial park
In factories and industrial areas, fire-resistant ductwork helps to supply fresh air, extract hot air, smoke, dust, or toxic gases, protecting workers' health and reducing material damage in the event of a fire. This ductwork system is especially important in warehouses storing flammable materials and production areas with a high risk of fire and explosion.
Basement, parking lot, and utility shafts
Basements, parking lots, and utility shafts are places where smoke, toxic gases, and heat accumulate during a fire. Installing fire-resistant ventilation ducts in Hai Phong, combined with smoke extraction and stairwell pressurization systems, helps control airflow effectively, reducing the risk of smoke inhalation and protecting property.
Things to note when choosing fire-resistant air ducts in Hai Phong.
When choosing fire-resistant ducting in Hai Phong, ensuring a reputable source and quality of materials is crucial for safe and efficient system operation. Simultaneously, thoroughly checking technical documentation, EI certification, and adhering to proper fire safety installation procedures helps reduce risks and optimize fire protection for the building.
- Choose a reputable manufacturer: Prioritize suppliers with modern factories and integrated CNC machinery to ensure the quality and accuracy of each product.
- Complete technical documentation and EI certification required: Check EI certification, fire-resistant material test reports, and acceptance documents to ensure the system meets fire safety requirements.
- Inspect the quality of materials and joints: Ensure that all joints, corner brackets, and matching accessories are securely machined, minimizing smoke and air leaks during operation.
- Construction must adhere to design and fire safety standards: Installation must follow the drawings, comply with standards for suspension, connection, and acceptance testing to reduce risks and enhance the safety of the building.
