Presumably it sagged, and the ends came away from the sides? I've seen
that happen. Bad design -- either an inappropriate design for the
material, or an inappropraite material for the design, depending on
your point of view :-)

Manufacturers of computer room raised floors will disagree with that --
all the high-load ones I've ever coma across are made of particle board
(usually with a very thin metal cladding, which is to protect against
moisture and impacts, and to provide electrical continuity). Of
course, these are 35mm-45mm thick, not 15mm-18mm.
