Fire Rated Ductwork

 

Fire Rated Ductwork is a specially designed, manufactured, and certified ventilation duct system. It maintains structural integrity for a specified duration during building fires, preventing the spread of flames and high-temperature smoke through the ventilation system. As an integral part of HVAC systems, it serves as a critical "life safety pathway" guardian in the passive fire protection system of modern buildings. Adhering strictly to international and national standards, our Fire Rated Ductwork products utilize advanced materials and innovative structural designs to provide reliable fire protection barriers for commercial complexes, hospitals, hotels, subway stations, and industrial facilities.

1.Graded Fire Resistance for Diverse Needs

With "fire resistance rating" as the core indicator, the product is classified into multiple grades. It can be precisely matched to fire safety requirements based on building types and duct installation areas, ensuring reliable protection.

2. Special Material Combination: Balancing Performance & Durability

Adopting a "base material + fireproof coating/composite layer" structure: the base material uses high-temperature resistant galvanized steel sheets, aluminum foil, etc., while the surface is compounded with flame-retardant materials such as fireproof coatings for dual protection. It integrates high-temperature resistance, corrosion resistance, and anti-aging properties, suitable for humid and corrosive environments, reducing maintenance costs.

3. Efficient Smoke Insulation to Mitigate Smoke Hazards

By optimizing the sealing structure and the smoke barrier performance of materials, it effectively prevents the spread of toxic smoke during fires, maintaining a safe air environment in evacuation and refuge areas.

4. Strong Structural Stability for Complex Installation Scenarios

It maintains structural integrity at high temperatures and supports multiple connection methods such as flanging and socketing. Adaptable to complex layouts like right-angle bends and diameter changes, it meets installation requirements across commercial, industrial, rail transit, and other scenarios.
