The Butterfly-Shaped Air Membrane Canopy at Zhangjiagang Station

The canopy features a butterfly-shaped hyperboloid shell membrane structure, which is both visually striking and structurally sound. This design not only provides an iconic appearance but also offers practical benefits such as shelter from the elements for passengers. The use of advanced membrane materials ensures durability and low maintenance, while the sleek design adds a modern touch to the station.

The construction difficulty of the butterfly-shaped canopy project is extremely high. Its steel structure is a single-layer hyperbolic shell structure system, with large wings having a space of about 50 meters and a short space of about 25 meters, small wings having a long span of about 35 meters, and a short span direction of about 15 meters. During the construction process, each steel structural member is different. The construction team uses 3D modeling technology to assist in processing and production. This high-precision construction process shows the progressiveness of Wanhao on modern architectural technology.

The butterfly-shaped canopy serves multiple purposes. Functionally, it provides a comfortable waiting area for passengers, protecting them from rain and sun. Aesthetically, it enhances the overall look of the station, making it a more welcoming and visually appealing space. The canopy's unique design also reflects the local culture and natural beauty of the butterfly, symbolizing transformation and progress.

The butterfly shaped canopy project at Zhangjiagang Station, with its tensile roof design, exquisite craftsmanship, and significant importance, has become a shining business card of Zhangjiagang City and injected new vitality into the city's future development.In the future, Zhangjiagang High speed Railway New City will rely on the transportation hub advantages of high-speed railway stations to become a first-class hub city in the core area of the Yangtze River Delta. The butterfly shaped canopy, as an important symbol in this process, will witness the takeoff and development of Zhangjiagang City.
