WCD is using 25 GA furring channels attached to metal stud members suspended by drop supports at our Hampton Inn project in Hollywood Ca. . We frequently use this type of secondary ceiling (drop ceiling) in apartments & hotels to conceal mechanical, electrical & plumbing in the overhead. This application is more cost effective than acoustical ceilings or pre-manufactured ceiling systems. WCD is constantly offering value engineering suggestions such as this to help control costs on the builders end.
