Interior Ventilation Ductwork Project of Beijing West Railway Station

Application Environment

The project must comply with national requirements for fire resistance rating, airflow volume and pressure, as well as the use of non-combustible materials in station construction. Since most of the system is installed in underground environments, a high level of corrosion resistance is also required.

In large transportation hubs like Beijing West railway station, ventilation systems must operate under high humidity, complex zoning, and continuous demand using environment. Compared to standard galvanized materials (like40-60g/m² Zinc products), high-zinc galvanized (e.g., Z275 and above) offer significantly enhanced corrosion resistance effect, effectively extending service life and reducing maintenance needs. Especially in hard-to-access areas like underground corridors and mechanical shafts, it provides a great performance in limited project budgets.

Using this material also help to maintain excellent formability, and implement efficient on-site fabrication and installation. With a lighter weight than stainless steel, it ensuring structural strength and help to reduce hoisting difficulty and decreasing overall construction costs.

Striking a practical balance between performance and cost, high-zinc galvanized ducts are becoming a preferred choice for public building ventilation systems, which also supporting both long-term reliability and modern sustainability goals.
