A wall facing panel includes a metal base and an outer layer with the thickness d1, on the front face of which there are elements making up a design with textured structure containing convex elements and concaves, with an interlayer with the thickness d2=0.005−300 mm; the textured design formed by the elements features convex elements with a maximum diameter of 0.01 mm to 25 mm and concaves with a width of 0.01 mm to 25 mm and a depth not exceeding 0.95 d1=0.02−5.0 mm; the textured design is formed in conformity with the condition where Sconv/Sconc=0.1−19.0 where Sconv is the combined area of the convex elements, and Sconc is the combined area of the concaves; the concaves can be filled with hardened material.
