Quick Details

ROOF OF LARGE-SPAN GRID STRUCTURE STADIUM

The project is a skylight dome construction located in Baiyun District, Guangzhou, and forms part of a large-scale commercial development. It includes nine smaller skylights and one large central atrium dome. The main atrium skylight features a single-layer welded spherical node latticed shell structure, with a projected area of approximately 4,000 square meters, a span of 32.12 meters, and a length of 63.78 meters. This dome not only fulfills the daylighting requirements of a large interior space but also strikes a perfect balance between aesthetics and functionality, making it one of the key highlights of the commercial plaza.
