Work surfaces for desks and tables in a data processing installation are formed of a laminated structure that has outer layers of a thin hard material and an inner core of a thermoplastic. The thermoplastic is in the form of plastic tubes or straws that extend from one outer layer to the other. It has been found that metal inserts can be located between the core and the outer surfaces and bonded to these layers. During the manufacturing process, flat pieces of sheet metal of suitable shapes are inserted on top of the thermoplastic core. A heated platen is lowered onto the core and the inserts and then heated, and pressure causes the straws of the core to deform around the inserts. The outer surface layers are then bonded to both sides of the core.
