This type of floor consists of a gridded metal framework or understructure of adjustable-height legs called pedestals, that provide support for individual floor panels which are usually 2×2 feet or 60×60cm in size. The height of the legs/pedestals is dictated by the volume of cables and other services provided beneath, but typically arranged for a clearance of at least six inches or 15cm.
Benefits and advantages
A raised floor (also raised flooring) is a type of floor used in office buildings with a high requirement for servicing, such as IT data centers, to carry cables, wiring, electrical supply and sometimes air conditioning or chilled water pipes. Additional structural support and lighting are often provided when a floor is raised enough for a person to crawl or even walk beneath.
