A car floor for passenger or freight elevators with composite or sandwich construction contains in its core a lattice-like structure (3) of longitudinal (4) and lateral (5) slats which cross over each other, and which is irremovably joined to the baseplate (2) and the cover plate (1). A car floor of this type is resistant to bending and twisting and has a high resonant frequency. If the car floor is made of steel, the elements of the composite structure are joined together by means of plug welding.
