Nanjing Datongguan Curtain Wall is a high-performance building envelope solution integrated with prefabricated three-dimensional steel pipe truss systems, engineered by Jiangsu Andy Steel Structure Co., Ltd. This product is specially designed for large-span construction projects, with a proven track record in the 5000-square-meter Singapore Tennis Stadium Steel Truss Roof project. It combines structural stability and architectural aesthetics, minimizing on-site welding and fabrication work through off-site prefabrication. The system is tailored to meet the rigorous demands of modern large-scale buildings, delivering a perfect balance between functionality and visual appeal for global clients. Its modular design also allows for seamless adaptation to different building scales and design concepts, making it a versatile choice for international construction projects.

The steel truss component of the Nanjing Datongguan Curtain Wall excels in stadium roof projects. Its lightweight yet robust structure can bear heavy loads while ensuring a spacious, unobstructed interior space, which is ideal for tennis courts, badminton halls and other sports venues that require large-span, load-bearing roof structures. The anti-corrosion coating also makes it suitable for outdoor sports facilities exposed to various weather conditions.
The product’s high anti-rust performance and durable structure make it a top choice for dry coal storage sheds and large logistics warehouses. Its flexible composition allows for easy installation of doors and daylighting components, optimizing the storage environment by enhancing natural light intake and ventilation. The prefabricated parts also speed up the construction of large-scale storage facilities, reducing project downtime.
For public buildings like exhibition halls and terminal buildings, the system’s aesthetic design and fast installation feature can significantly shorten the construction period. It also meets the high standards of both appearance and functionality required by public infrastructure projects, blending in with modern architectural styles while providing reliable structural support for large passenger and exhibition flow areas.
