An immediately loadable ceiling, which permits any type of floor construction and simultaneously provides a visible quality ceiling ready for use, can be assembled in record time using the Profidecke. The high level of pre-assembly and the perfect fitting accuracy of the individual elements enable rapid laying on the building site. The short assembly time and easy of machining mean that the Profidecke element is a cost-effective, environmental alternative to conventional reinforced concrete ceilings and wooden beam ceilings.
