This project is the Bajiaowan International Convention and Exhibition Center in Yantai, this all-metal stepped platform is particularly eye-catching. This project fully demonstrates the charm of the design scheme. Swaged I-bar is used as the floor material, with a spacing of only 11.1 millimeters, which perfectly solves the problem of high-heeled shoes getting stuck and also has strong drainage performance. The fences on both sides all adopt products of Expanded. They are connected to the main structure through bolt installation to ensure stability, leaving no welding marks and making the overall appearance more aesthetically pleasing.
