On the afternoon of April 24th, a significant construction milestone was achieved at the Xiamen Taikoo Xiang'an Airport Maintenance Base Project, where C&D Holsin participated. The steel structure roof of Hangar 1 was fully lifted and joined, marking a major construction phase for the world's largest single-structure civil aviation maintenance hangar in terms of size and span.

The steel structure of Hangar 1, weighing 11,393 tons and with a maximum single-span of 269.5 meters, presented substantial assembly challenges. C&D Holsin, serving as the supervisory unit, strictly adhered to regulatory standards and guidelines throughout the process, enhancing inspections and safety controls to ensure a smooth completion. Holsin Testing, as a third-party testing organization, also contributed to the project's safe progress through meticulous non-destructive testing of the steel structure welds.
