Abstract: Disclosed is a grid-shaped mat which is used especially for protecting floors or strengthening a floor cover. Said grid-shaped mat comprises a number of strip-shaped elements (1, 1?; 1?) which are bent several times, extend in a longitudinal direction (A), and form the grid structure of the mat (10). The lateral length (b) of the element (1, 1?; 1?) that is longer from a cross-sectional perspective runs perpendicular to the longitudinal direction of mat. At least two adjacent elements (1, 1?) are hingedly connected to each other with the aid of at least one pin (2) that extends in the longitudinal direction (A) of the elements, respectively. Such a mat is easy to produce while the floor cover that is applied to the mat coheres significantly better after drying and hardening than when a conventional wire grill is used.
