A reinforcing mesh element for embedding in a cement matrix of a building structure, preferably in a corner region or in a curved region. The reinforcing mesh element has a grid-shaped arrangement of fiber bundles that are embedded in a plastic matrix. The reinforcing mesh element has at least one rigid zone and at least one flexible zone. In the at least one flexible zone the plastic matrix consists of an elastomer plastic. The plastic matrix comprises in the at least one rigid zone a thermoset plastic. The flexible or rigid form of the reinforcing mesh element is thus obtained, due to the set-up of the plastic matrix. Additional stiffening bodies or stiffening elements that are connected with the grid-shaped arrangement can be omitted. The reinforcing mesh element can be adapted to the respective situation and simplifies handling when manufacturing a building structure.
