Shijiazhuang Metro has taken a major step in enhancing its ventilation systems by adopting a new generation of ductwork produced with water-blown foam technology. Significantly, this advanced material—once exclusively imported—is now manufactured domestically, greatly reducing project costs and shortening delivery timelines without compromising quality.
This innovative duct system offers multiple advantages that are particularly valuable in high-traffic public transport environments:


Easy Installation & Rapid Construction
The lightweight and modular design allows for quick assembly, significantly cutting down on installation time and labor costs while minimizing disruption to ongoing rail operations.

Cost-Efficiency & Long Service Life
Local production makes these high-performance ducts affordable, and their extended lifespan ensures lasting value and reduced maintenance needs.

Hygiene and Safety
The smooth, non-porous interior resists dust accumulation, inhibits microbial growth, and is easy to clean—essential for maintaining healthy air quality in crowded metro systems.
Corrosion Resistance & Durability
Suitable for demanding environments, the material offers high resistance to corrosion and wear, extending system reliability even under intense usage.
Fire Resistance and Seismic Performance
The ducts meet stringent international safety standards, providing enhanced fire retardancy and earthquake resilience—critical features for ensuring passenger safety in underground public transport hubs.
The shift to domestic manufacturing reflects not only China’s growing expertise in advanced material production but also the strategic move toward localized supply chains that offer economic and logistical benefits.

This upgrade reinforces Shijiazhuang Rail Transit’s commitment to safety, sustainability, and operational excellence. By incorporating environmentally friendly production processes and designs tailored for modern urban infrastructure, the new ventilation system offers cleaner air, greater energy efficiency, and peace of mind for millions of passengers.
Ideal for subway and light rail applications, this duct solution sets a new benchmark in combining performance, safety, and cost-effectiveness—all made possible through innovation and independence in advanced manufacturing.
