(57) The invention relates to a concrete element (10) delimited at least partially by planar side surfaces (11), wherein the side surfaces (11) meet along edges (12), and wherein the concrete element (10) comprises a metal frame (20) having edge profiles (21) extending along the edges (12), which are fixed to each other and cast into the concrete element (10). The invention also relates to process for producing a concrete element (10), wherein a formwork (100) is formed by:

- providing a metal frame (20) with edge profiles (21) fixed to each other, and

- releasably attached to the metal frame (20), from the outside of the metal frame (20), formwork elements (110) which together delimit a casting volume (200), thenpouring castable concrete into the casting volume (200), thereby casting the metal frame (20) into the concrete, and after the concrete has set, removing the formwork elements (110) from the metal frame (20) and leaving the metal frame (20) in the concrete element (10). The invention also relates to a formwork (100) for casting a concrete element (10) according to the invention.
